2X SCD41 Gas Sensor Module Detects CO2,Carbon Dioxide,Temperature and Humidity in One Sensor leírása

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.
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 .
