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

SCD41 Gas Sensor Module Detects CO2,Carbon Dioxide,Temperature and Humidity in One Description

Carbon dioxide is a key indicator of indoor air quality, damaging human cognitive ability and happiness. SCD41 is 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. features Reference accuracy, specified range 400-2000 ppm Supply voltage range: 2.4 - 5.5 V High accuracy: (40 ppm + 5%) Digital I2C interface Integrated temperature and humidity sensor Low power operation to Less than 0.4 Ma average @ 5 V, 1 meas/ 5 minutes Interface definition: 1.
