Pollution is a problem that affects everyone, no matter where they live. Even if you reside in a rural area, you are still subject to many types of pollution, both outdoors and inside your home.
Today we will look at several air quality sensors that you can use with a microcontroller. We’ll test them out using both an ESP323 and an Arduino, and we’ll also compare the readings to a commercial air quality meter to see if there is any correlation between readings.
We’ll be taking a look at the following sensors:
- MQ Gas Sensors (various models).
- PMS5003 PM2.5 Particulate Matter Sensor.
- BME280 Temperature, Humidity & Air Pressure Sensor.
- BME680 Temperature, Humidity & Gas Sensor.
- AHT20 Precision Temperature & Humidity Sensor.
-CCS811 Air Quality Sensor.
- SGP30 Air Quality Sensor.
- SGP40 Air Quality Sensor.
We’ll see how they work and what parameters they can measure, and we’ll hook them up and run a demo.
Then we’ll put a bunch of sensors together on an ESP32 to make an environmental monitoring platform.
