SCD41 Gas Sensor Module CO2 Carbon Dioxide Temperature and Humidity Gas Sensor Module I2C Communication 2.4-5.5 V for Air Quality Monitoring (SCD41)

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 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.Features:Reference accuracy, specified rangeSCD40:400-2000 ppmSCD41:400-5000 ppmSupply voltage range: 2.4-5.5 VHigh accuracy: ± 5%Digital I2C interfaceIntegrated temperature and humidity sensorLow power operation to <0.4 Ma average @ 5 V, 1 meas/ 5 minutesBoard size: 13.4 × 21.6mmInterface:1.
