The team, led by Ravi Sharma, a 2nd year Electrical Engineering student at Cooper Union, built the sensors using industrial components and micro-computing modules and open-source code.
The sensor units can be equipped to measure and log indoor and outdoor environmental conditions.
The components tested include sensors capable of measuring the airborne toxins Nitrogen Oxides (NOX), Volatile Organic Compounds (VOC), Particulate Matter (PM 1, PM 2.5, PM 4, PM 10), CO2, and environmental conditions Relative Humidity and Temperature (RH/T). Future upgrades for other sensor types are in the works.
The remote sensors are programmed to find and connect to their "mothership", a mini-computer hub that acts as a wifi router and VPN, which collects real-time data from sensors within range, and securely delivers the stats to our server at Loisaida, which records and graphs the data for public
display via the web. The networking architecture, design and implementation is done by our Senior Tech Team, led by Daniel Bell of Bell Technologies and Loisaida's Paul Garrin.
Operating next to our prototype is a professional air quality monitor provided to us by Thermo-Fisher Scientific. The Thermo-Scientific GM5000 acts as a reference source for calibrating our lab-built units. In an ideal world, we would deploy hundreds of GM5000's but that proves much too costly for a neighborhood non-profit -- so we took on the challenge to build smaller ones from parts in order to lower the cost and deploy them in large numbers around the Loisaida neighborhood.
ECOLIBRIUM's air quality monitoring network is part of a NY State Department of Environmental Conservation Environmental Justice Grant which supports our "Environmental Justice and Literacy through Community Science" program.
Our goal is to inspire and up-skill our community to take effective actions to improve the health and wellbeing of our neighbors, and to create a roadmap toward climate-adaptation, mitigation, and economic opportunities through coordinated, well-timed actions from reducing energy waste, to zero emissions.
On this 10th anniversary of Superstorm Sandy's devastation to New York City, we must emphasize that facing the CLIMATE EMERGENCY is everyone's job. There's a role and shared-responsibility for all of us. We're all in it together.
