【SCD41 Gas Sensor Module】- This product has high precision and high cost performance. The module uses a 2.54mm pitch pin header interface to lead out the power supply and communication pins. On-chip temperature and humidity compensation is achieved through the built-in temperature and humidity sensor to measure humidity and temperature
【Adjust indoor ventilation systems】- SCD41 Gas Sensor Module can intelligently adjust indoor ventilation systems based on CO2 concentrations. Indoor air quality helps maintain a healthy and efficient environment at low CO2 concentrations over a period of time
【Product Parameters】- Benchmark accuracy, specified range: SD41: 400-5000PPM, supply voltage range: 2.4-5.5V, high accuracy: ±(40ppm + 5%), low power operation to 0.4mA, average value @5V, 1meas./5 minutes
【Note】- Please read the documentation first. By default it re-calibrates weekly, taking the lowest measurement as the reference. Depending on your environment, that may seldom go below 500-600ppm (or more)
【Pin Definition】- GND: negative power input port. VDD: positive power input port. SCL:12C clock port. SDA:12C data port
