Scd41 Sensor Module Detects Co2,carbon Dioxide,temperature and Humidity In One Sensor

Carbon dioxide is a key indicator of indoor air quality, damaging human cognitive and happiness. SCD41 is generation of -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.featuresReference accuracy, specified range 400-2000 Supply voltage range: 2.4 - 5.5 VHigh accuracy: (40 + 5%)Digital I2C interfaceIntegrated temperature and humidity sensorLow power operation to Less than 0.4 Ma average @ 5 V, 1 meas\/ 5 minutesInterface definition:1.
