Citizen Science Apps: Interaction, Interoperability, Innovation

handyhandbildNaturblick, a project of the Museum für Naturkunde Berlin and the European Citizen Science Association (ECSA) are co-organizing the workshop “Defining principles of mobile Apps and platforms development for best practice in citizen science: Interaction, Interoperability, Innovation” which will be held on the 13th and 14th of December in Berlin.

In Citizen Science new technological tools are being developed to efficiently gather information and manage the great amount of spatial and temporal databases generated by Citizen Science projects. These digital tools should be designed in a way that simplifies data gathering, enhance society participation and scientific understanding. Therefore a variety of fields need to be incorporated into the development process: e.g. technical development, science, data management, design, user interaction, education and outreach. Experience shows there are many pitfalls on the way to a successful product.

The workshop is aimed at actors with experience in Citizen Science Apps and platform development, Data, Tools and Technology, Best Practice, Education and Communication. Together we will identify principles to develop mobile Apps and platforms for environmental and biodiversity data management, with reference to the 10 Principles of Citizen Science (ECSA 2015).

In a two-day workshop we will have presentations on Citizen Science Data, App development and hear from projects about success and failure in development, engagement and user interaction. In working groups we will define principles building on different perspectives and bring them to live with rapid prototyping.

Leveraging AirBeam Data to Inform Policy Decisions

Leveraging AirBeam Data to Inform Policy Decisions

Carting Workers’ PM2.5 ExposuresAirbeam is a great example of the type of senor network platforms Rock 'n Renew helps implement for local communities, schools, and businesses. When these platforms are installed, it makes local municipalities existing systems much more efficient. Knowledge really is power!

New York City recently committed to implementing a “zoned” collection system for the commercial waste sector. By dividing the city into zones and having commercial carting companies bid to service each zone, the city’s study found that the number of miles traveled by private collection vehicles will be cut by an astounding 49 to 68 percent!  This is a win for both the private carting companies, which will be able to achieve dramatic efficiencies in operations, and everyday New Yorkers, who will have to contend with less noise and air pollution. 

AirCasting: Recording, mapping, and sharing health and environmental

Air Caster Crowd Sensing Platform
Air Caster Crowd Sensing Platform

As Rock ‘n Renew prepares to launch our biggest program yet, The EcoBlockchain, we are in the final stages of researching the best Internet Of Things technology for EdTech and Environmental Management. Air Caster is a fantastic example of the types of platforms we are bringing together under one easy-to-use framework.

AirCasting is a platform for recording, mapping, and sharing health and environmental data using your smartphone. Each AirCasting session lets you capture real-world measurements, annotate the data to tell your story, and share it via the CrowdMap.

Using the AirCasting Android app, AirCasters can record, map, and share:

  • Sound levels recorded by their phone microphone;
  • Temperature, humidity, and fine particulate matter (PM2.5) concentrations recorded by the Arduino-powered AirBeam;
  • Temperature, humidity, carbon monoxide (CO) and nitrogen dioxide (NO2) gas concentrations recorded by the Arduino-powered AirCasting Air Monitor;
  • Heart rate, heart rate variability, R to R, breathing rate, activity level, peak acceleration and core temperature measurements recorded by the Zephyr BioHarness 3; and
  • Heart rate measurements recorded by the Zephyr HxM.

Using AirCasting Luminescence, these sensor streams can also be represented using LED lights.

To start recording, mapping, and sharing sound level data for your neighborhood, simply download the Air­Casting app to your Android device and press record.  Want to record Air Quality data? Buy an AirBeam, download the AirCasting Air Monitor DIY guide, or build your own monitor and connect it to the AirCasting platform.

Who Uses AirCasting?

There are thousands of active changemakers currently using the AirCasting platform, including community-based organizations, schools, research institutions, and citizen scientists interested in health and environmental monitoring, electrical and mechanical engineering, design, rapid prototyping, and open source code. We are actively recruiting additional AirCasters to join our movement. We are seeking . . .

Instrument Makers interested in developing AirCasting compatible sensor packages for new environmental and physiological sensing applications. It’s simple to connect your own custom-designed sensor package to the AirCasting app to display and record measurements in real-time.

Educators & Community Leaders interested in applying science, technology, engineering, art & design, and mathematics to address urgent environmental issues where they live. Schools and community organizations are the vital link between our technology and its application to real world problems.

Open Source Coders to push the limits of what’s possible with the AirCasting platform – gamify, add social networking layers, improve instrument performance & communications – the possibilities are truly endless. Because sharing information freely empowers communities to develop their own best solutions, everything we do, from hardware to software, is open source.

Citizen Scientists from around the world to take measurements, contribute to the crowdmap, and make change! We live in a world where expert knowledge is no longer the exclusive province of experts, where citizens, armed with affordable and accessible instruments, can make unprecedented contributions to scientific understanding.

ATTN Hardware Developers

It’s simple to connect your own custom-designed sense device to the AirCasting app to display and record sen­sor measurements. Just do the following:

  • Download the AirCasting Arduino sketch, which controls the sensors and sends data to the app via Blue­tooth.
  • Alter the Arduino sketch to communicate your sensor data.
  • Use the AirCasting app to send your data to the AirCasting servers for display on the AirCasting website. Want to send the data to your own servers? Just specify the URL in the AirCasting app settings, “Menu” > “Settings” > “Backend settings”.

Open Source

AirCasting is an open source project. The AirCasting app and website code is on GitHub as is the AirBeam firmware and the electronic schematics for the AirBeam. The STL files for 3D printing the AirBeam & LiteBeam enclosures can be downloaded from Shapeways.

How to Use the AirCasting Maps

The health and environmental data collected by AirCasters can be filtered and displayed on the AirCasting website maps using one of two views: “CrowdMap” and “Sessions”. Use the tabs on the filter menu located on the right hand side of the screen to toggle between the two. The CrowdMap view is the default.

The CrowdMap displays AirCasting data from all contributors. Each square’s color corresponds to the average intensity of all the measurements recorded in that area.  Click on a square to view the underlying data. Refer to the “Heat Legend Units” to identify the intensity range for a square. For example, an orange square corresponds to an average sound level between 71 and 80 decibels. If no colors are displayed, there’s no data in that area.  Note that the relationship between measurement ranges and colors can be adjusted using the “Heat Legend Units” filter.  By default the CrowdMap displays sound level data from phone microphones. To view data from other sensors, use the “Parameter – Sensor” filter.  You can also filter the CrowdMap by “Location”, “Time Range”, “Tags”, or “Profile Names”. Increase the “CrowdMap Resolution” to display averages for smaller areas. Click “submit” to display your filter selections.

The Sessions map displays the routing and intensity information for AirCasting sessions.  To view a session, select a session from the “Sessions List” located on the left hand side of the page. A dot’s color corresponds to a measurement’s intensity at that location. Refer to the “Heat Legend Units” to identify the intensity range for a measurement. For example, a yellow dot corresponds to a sound level measurement between 61 and 70 decibels. Note that the relationship between measurement ranges and colors can be adjusted using the “Heat Legend Units” filter.  Hover your mouse over a dot to generate a tooltip with the exact measurement. Filter the AirCasting Sessions list by “Parameter – Sensor”, “Location”, “Time Range”, “Tags”, or “Profile Names”.  Click “submit” to refresh the Sessions list. To view multiple sessions at once, you must first select a “Parameter – Sensor”.  To graph the measurements from a single session, toggle the “Sessions Graph” arrow at the bottom of the screen.  Hover your mouse over the graph to see the corresponding location on the map along with the measurement for that time period.  Zoom in on the graph by clicking and dragging with your mouse or clicking the time frame buttons at the top of the graph.  When zoomed in, pan through the data using the slider at the bottom of the graph.

To get a better view of the map, hide page elements by toggling the arrow in the upper right hand corner. Generate and share a permalink using the permalink button in the upper right hand corner or simply copy and paste the address from the browser window.

AirCasting is a HabitatMap Project

HabitatMap is a non-profit environmental health justice organization whose goal is to raise awareness about the impact the environment has on human health. We build tools to support grassroots environmental organizing, including – our community mapping platform – and AirCasting.


There are dozens of people who contributed time and effort to make AirCasting a reality. In particular, we’d like to thank Marcin Kostrzewa and the Lunar Logic team for their work on the AirCasting software, Raymond Yap for prototyping AirCasting hardware and firmware, Tim Dye for advising on data quality, Chris Cosentino for designing the AirBeam and LiteBeam enclosures, Garrett Berg for designing the AirBeam PCB, Thomas Deckert for designing an early version of the AirBeam enclosure, Dave Young and Guan Yang for consulting on the AirBeam PCB design, Alex Besser for his work characterizing AirBeam performance, and Iem Heng, who is gone but not forgotten, for his work prototyping AirCasting hardware and firmware.


The AirCasting platform and the AirBeam would not have been possible without the generous support of our funders and the partnerships they’ve enabled. Support for AirCasting and the AirBeam have been provided by: Knight Foundation through a partnership between HabitatMap and Sonoma Technology; the New York State Dept. of Environmental Conservation through a partnership between HabitatMap and Newtown Creek Alliance and HabitatMap and UPROSE; the EPA through a partnership between HabitatMap and Sustainable South Bronx; the Hive Digital Media Learning Fund of the New York Community Trust through a partnership between HabitatMap and New York Hall of Science; the Mozilla Hive NYC Learning Network through a partnership between HabitatMap, Parsons the New School for Design, and New York Hall of Science; NIEHS, EPA, and HHS through a partnership between HabitatMap and researchers and engineers from New York University and Carnegie Mellon’s CREATE lab; New York State Pollution Prevention Institute through a partnership between HabitatMap and New York Hall of Science; the Grey Area Arts Foundation through a partnership between HabitatMap, Sonoma Technology, and AethLabs; and Google Earth Outreach.

Hans Rosling:Making Climate Statistics Exciting (so we will pay attention)

Distributing the burden and shouldering the solutions together to solve the population growth issues we are facing.
Distributing the burden and shouldering the solutions together to solve the population growth issues we are facing.

When handled with care – global statistics can help challenge common myths and misconceptions about the world, Rosling hopes. Chief among the myths still to be debunked, he says, is the idea that the world is split in two – with a developed world on one side and a developing world on the other. “We don’t have two types of countries any longer, we have four or five types … [and] the idea that the western world will be ahead of the rest for ever is wrong.”
This plays a particular role in the following video which shows how quickly things can shift.

Compost Tea

Ever wondered how to make compost tea?

“Compost tea is an effective, low-strength, natural fertilizer for seedlings and garden plants, and it can suppress fungal plant diseases. The tea-brewing process extracts, and in some cases grows and multiplies, nutrients and beneficial bacteria and fungi from compost and suspends them in water in a form that makes them quickly available to plants.”-Organic Gardening

Compost tea is great for your garden, and it is easy to make to! You can purchase bags of compost tea at the store, or you can just make your own.

compost tea

How to Make Compost Tea

There are two ways that you can do this.

1. You can place compost and water in a barrel or container with a 1 pound compost to 1 gallon water ratio. Stir your mixture with a stick for about 5 days. Strain the liquid from your mixture with cheesecloth or burlap.

2. You can also place your compost into a porous bag or nylons, using it as a tea bag. Place the bagged compost into a bucket of water and let it steep for several days.

Use the compost tea all over the garden. Your plants will love it!

Compost Tea Tips

1. When you brew compost tea, be sure to use mature, sweet, earthy-smelling compost. If your compost smells unpleasant, it could be anaerobic, and few beneficial microbes survive in this environment.

2. Don’t apply compost tea to any vegetable within 3 weeks of its planned harvest date.

3. You can add extra nutrients to your compost tea like molasses, seaweed, or fish emulsion.

Peas, Emerging From The Deep Freeze

By  published in The New York Times: April 30, 2014

Which cuisine do you think of when you think about peas? French, with petits pois aux laitues? Italian, which offers piselli con prosciutto? Indian, and its mutter paneer? British, with buttered peas with mint?

And when you reach for peas, are they frozen or fresh?

Worldwide, most peas are consumed straight from the deep freeze. Many would argue that frozen peas are the better choice, for quality. They certainly can’t be beat in terms of convenience, and they do taste good. I am not immune to their charms when pea season is still a ways off.

An Edible Education

Here at Rock ‘n Renew, we love engaging students in gardening and an edible education. Our students get to spend lessons outside in the fresh air getting their hands dirty. They are able to get in touch with the environment and our agricultural roots in cities where it is hard to find much green space, let alone vegetable gardens.

School gardening projects are sweeping across the nation. Those of us who spend time with children in the garden have seen firsthand anecdotal evidence of how much gardening positively influences the lives of our students. It provides them with hands on education in science, environment, and local food systems. Students need direct contact with nature and our planet to appreciate and value its conservation. Unfortunately, urban spaces tend to be riddled with litter, graffiti, pollution, and tend to lack green spaces and fresh produce. Gardening helps our students reconnect to the earth and become inspired to think about their daily choices and how it affects the environment and their health.

Plant-based activities, gardening, and environmental studies provide great opportunities for implementing National and State Science Education Standards. Such opportunities go far beyond the basic study of plants themselves to include life cycles, ecosystems, soil, weather, organisms, and many science process skills such as measuring, charting, collecting data, and reporting.

One of the key premises of contemporary school gardening advocates is that garden-based lessons…

  • Help students meet performance standards across disciplines
  • Appeal to different learning styles
  • Apply concepts through the contexts of real-world experiences
  • Provide rich activities and experiences for students of all learning abilities
  • Are student-centered

We just finished composing a Rock ‘n Renew School Garden Guide. It is a comprehensive detailed guide on how you can start a school garden! We have several versions based on the scope and scale of your vision. We also have a special Garden Guide that was created by our students, for other students. Email us to receive a free copy.
