The M5Stack CO2 Unit w/ Temperature & Humidity Sensor (SCD40) is a photoacoustic Carbon Dioxide (CO2) Unit that will tell you the CO2 PPM (parts-per-million) composition of ambient air.

With a built-in Sensirion SCD40 sensor, power by Buck converter circuitry, and I2C communication. It has a range of 400~2000 ppm with an accuracy of ± (50 ppm + 5% of reading). What’s more, it supports temperature and humidity measurement too. Perfect for environmental sensing, scientific experiments, air quality and ventilation studies, and more.

Applications

• Environmental sensing
• Air quality
• Ventilation studies
