SCD40 Purple Gas Sensor Module for Carbon Dioxide Detection Temperature and Humidity in One IIC Communication

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.
