Product Description
Product Description
The Gravity: I2C SCD41 Infrared Carbon Dioxide / CO2 Sensor (400 - 5000 ppm) is a carbon dioxide sensor module from DFRobot based on the Sensirion SCD41. It is intended for CO2 measurement in indoor air and environmental monitoring applications and uses the photoacoustic NDIR sensing principle. The specified measuring range is 400 to 5000 ppm.
An integrated temperature and humidity sensor is used for on-chip signal compensation. Temperature and humidity data are also available as outputs from the module. Communication is provided through an I2C interface; the source data specifies I2C address 0x62 for the sensor. Supply voltage is 3.3 to 5 V, and the CO2 response time is 120 s.
