SCD40 Purple Gas Sensor Module for Carbon Dioxide Detection Temperature and Humidity in One IIC Communication
Description:
- Carbon dioxide is a key indicator of indoor air quality that impairs human cognitive ability and happiness. SCD40/SCD41 is the next generation of miniature carbon dioxide sensor for Sensirion. SCD40/SCD41 has high accuracy and high cost performance. The module leads out the power supply and communication pins with 2.54mm spacing pin interface. On-chip temperature and humidity compensation realizes humidity and temperature measurement through built-in temperature and humidity sensor. SCD40/SCD41 can realize intelligent adjustment of indoor ventilation system based on carbon dioxide concentration, and indoor air quality helps to maintain a healthy and efficient environment under low carbon dioxide concentration for a period of time.
