ESP32 Air Quality Sensor with PMSA003 + BME680 and 1.14" LCD
Air quality sensor integration board that couples together the following modules:
I use this to track the AQI in my home. This sensor measures within 1% of 3x different PurpleAir sensors scattered around my neighborhood. The PMSA003 particulate air sensor module in this build should be an improved version the PMS5003 found in the PurpleAir sensors.
Combined with Home Assistant, InfluxDB, and Grafana I can track the long term air quality inside and outside my home.
