Description
SCD40 is a photoacoustic CO2 Sensor Module that it comes with integrated Temperatures and Humidity Sensing features as well. It is a industrial grade, highly accurate CO2 measurement sensor that is capable to detect CO2 0 to 40000ppm with an accuracy of +/-5% on 400-2000ppm range.
Product introduction Carbon dioxide is a key indicator of indoor air quality, damaging human cognitive ability and happiness. SCD40 is the next generation of micro carbon dioxide sensor 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 chip temperature and humidity compensation realizes humidity and temperature measurement through built-in temperature and humidity sensor. SCD40 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 < 0.4 Ma average @ 5 V, 1 meas/ 5 minutes Interface definition: 1. GND: negative input port of power supply 2. VDD: positive input port of power supply 3. SCL: I2C clock port 4. SDA: I2C data port
