SCD41 CO2 Gas Sensor module

Description : Carbon dioxide is a key indicator of indoor air quality, damaging human cognitive ability and happiness. SCD41 is the next generation of micro carbon dioxide sensor of Sensirion. SCD41 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. SCD41 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.
