CanAirIO

Citizen science project with mobile and fixed sensors for measuring air quality (PM 2.5) using low-cost sensors and smartphones. Built with a ESP32 module board and some dust sensor, like Sensirion, Panasonic, Honeywell and Samsung interfaced with an CanAirIO Android app.

This repo is a TTGO version of CanAirIO that supports two Air Quality sensors:

• [x] Panasonic PM Sensor
• [x] Bosch BME680 VOC sensor for IAQ.

Warnning: it is a alternative to CanAirIO firmware
