SCD40 SCD41 Gas Sensor Module Detect CO2 Carbon Dioxide Temperature and Humidity

DC 2.4-5.5 V SCD40 SCD41 Gas Sensor Module CO2 Carbon Dioxide Detection Temperature and Humidity 2 in 1 I2C Communication Board

Carbon dioxide is a key indicator of indoor air quality, damaging human cognitive ability and happiness. SCD40 is the next generation of micro carbon dioxide sensor of Sensirion. SCD40 has high precision and high cost performance. The module leads out the power supply and communication pins with a 2.54mm spacing pin interface. On chip temperature and humidity compensation realizes humidity and temperature measurement through built-in temperature and humidity sensor. SCD40 can realize intelligent regulation of indoor ventilation system according to carbon dioxide concentration. Indoor air quality helps to maintain a healthy and efficient environment under low carbon dioxide concentration for a period of time.
