Overview

Project Eclipse: a low-cost, accurate air quality sensing platform for cities

Poor air quality is something most urban residents experience regularly, but because it’s largely invisible and we lack sensors to help inform us it has become something of a “silent killer”. Linked to a number of serious health ailments, including heart and lung disease, as well as issues like asthma aggravation, the World Health Organization estimates that 91% of the world’s population live in places where air quality exceeds guideline limits. With Project Eclipse, the Urban Innovation Initiative presents a full stack -from sensors to analytics- air quality sensing platform for cities. The goal is a radical increase (10x – 100x) in the geographic granularity of environmental sensing in cities in support of a variety of public health scenarios.

 

Custom Hardware

Project Eclipse devices are custom designed, from the electrical engineering to the enclosure, and calibrated in our hardware lab at Microsoft Research in Redmond, WA. The sensors measure CO, NO2, SO2, and O3, as well as PM 1, PM 2.5, and PM 10, along with temperature and humidity. Data is transmitted via LTE-M direct to an Azure data stack. When taking hourly readings, each device should last about nine months on a single battery.

Full Azure Data Stack

Project Eclipse utilizes Azure to ingest, process, store, analyze, and visualize air quality data. Final raw data are available in JSON format via simple REST API, and the Urban Innovation team has developed custom R analytics, Power BI, and web visualizations to help customers monitor and get insight from the data.

Next Generation Sensors

The Urban Innovation team continues to work toward its goal of low cost, low-to-no power environmental sensors. Additional techniques under development include:

  1. Computer vision analytics for camera-based sensors
  2. Analogue colorimetric ink-based chemical sensors
  3. Hybrid electro-molecular sensors

 

Deployments

Project Eclipse is rolling out in partner cities. In Boston, for instance, Project Eclipse is partnering with the Beta Blocks program that is exploring the public value of technology in communities. In Miami, researchers on the Urban Innovation Initiative are working with local government and civic tech community members to identify pilot projects around low income housing and hyperlocal weather and pollution monitoring.

Green Citizens

Welcome to our FAQ Green Citizens!

 

What is it? This little leaf is an air quality monitor designed to measure the quality of Air or AQI (Air Quality Index)

What is it detecting? We can detect 4 gases: CO, NO2, SO2, and Ozone, in addition to particulate matter PM 1.0, 2.5, 10. We also measure temperature and humidity.

How often does it sample? It depends but anywhere between every 20 min to an hour.

Is it watching me? No, we have no cameras or mics installed.

How is it sending the data? We use an LTE cellular chip to send data to our Azure account that we share with the city.

What will you do with the data? We will work with the city to analyze and understand patterns of pollution over time. This data will be made public.
