SCD40/SCD41 Gas R Module Detects CO2, Carbon Dioxide, Temperature And Humidity In One R I2C Communication

Product introduction Carbon dioxide is a key indicator of indoor air quality, damaging human cognitive ability and happine. SCD40 is the generation of micro carbon dioxide r 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 temperature and humidity compensation realizes humidity and temperature measurement through built-in temperature and humidity r. SCD40 can realize intelligent regulation of indoor ventilation system according to carbon dioxide concentration. Indoor air quality helps to maintain a healthy and efficient envment under low carbon dioxide concentration for a period of time.
