The UNIT CO2 from M5Stack is a photoacoustic Carbon Dioxide (CO2) Unit that will tell you the CO2 PPM (parts-per-million) composition of ambient air.

The unit has a built-in Sensirion SCD40 sensor powered by buck converter circuitry and communication handled via I2C. It has a range of 400~2000 ppm with an accuracy of ±(50 ppm + 5% of reading).

It supports temperature and humidity measurements too - perfect for environmental sensing, scientific experiments, air quality and ventilation studies, and more.

Features

  • CO2 concentration detection
  • Temperature and humidity measurement
  • I2C communication (Add: 0x62)
  • Integrated 5V -> 3.3V Buck converter
  • 2x Brick holes
  • HY2.0 4-pin interface
