CanAirIO
Open-source firmware for ESP32-based air quality sensors, enabling citizen science monitoring of PM2.5 and CO2 levels.
What is CanAirIO?
CanAirIO Firmware is an open-source software package that transforms low-cost ESP32 microcontroller boards into functional air quality sensors. It reads data from attached PM2.5 or CO2 sensors and transmits it via WiFi or Bluetooth, enabling the creation of a distributed network for environmental monitoring. The project addresses the need for affordable, community-owned air quality data.
Citizen scientists, environmental activists, makers, and IoT developers interested in building or deploying low-cost, open-source air quality monitoring stations.
Developers choose CanAirIO for its strong focus on community, extensive hardware compatibility, and ease of use through features like a web installer and OTA updates. It provides a complete, ready-to-deploy solution that is more accessible and customizable than proprietary environmental monitoring systems.
Overview
CanAirIO is a citizen science initiative. We are developing a mobile application that is able to set a PM2.5 or CO2 sensors, and other related sensors, as a fixed station using WiFi or mobile station with an smartphone by using a Bluetooth connection.
