Module Specification
CO₂ Sensor
True NDIR CO₂ sensor with temperature and humidity, for indoor air-quality monitoring
Description
SCD40-based sensor that measures real CO₂ concentration (400–2000 ppm typical) using NDIR rather than estimating it. Temperature and humidity come along as calibration byproducts. Connects over I2C and reports on the sensor's native ~5s cadence.
