Unit CO2
Description
Unit CO2 is a digital air CO₂ concentration detection unit, built-in with Sensirion's SCD40 sensor and power step-down circuit, using I2C communication. This unit is suitable for air environment condition measurement, with a typical accuracy of ± (50 ppm + 5% of reading) for CO₂ measurement, and a range of 400 ppm ~ 2000 ppm, while also measuring ambient temperature and humidity.
