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.

SCD41 can measure CO2 concentrations in the range from 400 to 5000 ppm. In addition to measuring CO2, the SCD41 can also measure temperature and humidity. The sensor communicates through an I2C address and can be powered from 2.4V up to 5.5V. You can connect it to both ESP32 or ESP8266 and duino Uno or Raspberry Pi. You can connect the module via a pin comb or our uŠup connector (JST-SH). The module itself also has its own pull-up resistors for the I2C bus. The module can be attached with 4 2.2x5mm screws.
