A while ago, [Joshua Young] had a conversation with an environmental scientist. There aren’t many government-funded pollution monitoring stations around Texas, but there are a lot of well-off home owners associations in Houston that have the sensors to collect the data. Air quality monitoring is important, and more data is usually better, and without these HOA’s providing the data for free, these environmental scientists wouldn’t have the data to do their job.
[Joshua]’s project is taking the idea a few members of those HOA’s had and expanding it to the entire world. For his entry to the Hackaday Prize, he’s creating a system to share local pollution data with the entire Internet.
The system [Joshua] is building uses a suite of air quality sensors to measure sulfur dioxide, carbon monoxide, nitrogen oxides, ozone and particulate matter. These sensors connect to the Internet through either an ESP8266 WiFi module or a LoRa radio module, push the data onto the cloud, and let the entire world know what the air quality is.
Using tens of thousands of individual base stations to gather data has been done before; Weather Underground uses ten times as many weather stations than the National Weather Service to get better weather tracking resolution. Pollution sensors aren’t normally a part of a weather station, and with [Joshua]’s project, the environmental scientists tracking this data will hopefully get the data they need.
