SCD40 Gas Sensor Module 400-2000PPM CO2 Temperature Humidity Detection Module Air Quality Tester

Introduction:
- Carbon dioxide is a key indicator of indoor air quality. SCD40/SCD41 is a miniature carbon dioxide sensor with high precision and cost-effectiveness. The module uses a 2.54mm pitch pin interface to lead out power and communication pins. On chip temperature and humidity compensation is achieved through built-in temperature and humidity sensors to measure humidity and temperature. SCD40/SCD41 can intelligently regulate indoor ventilation systems based on carbon dioxide concentration, which helps maintain a healthy and efficient environment with low carbon dioxide concentration for a period of time.
