Gravity: I2C SCD41 Infrared CO2 Sensor (400 - 5000 ppm)
We have ✅ 1 available of the DF-SEN0536 in our Sydney warehouse. An extra 311 units available with a short lead time.
The Gravity SCD41 Infrared CO2 Sensor provides accurate carbon dioxide, temperature, and humidity measurements in a single compact module. Based on Sensirion's SCD41 sensor, it uses photoacoustic NDIR (non-dispersive infrared) sensing with patented PASens and CMOSens technology for high accuracy in a remarkably small form factor.
CO2 is a key indicator of indoor air quality — elevated levels can compromise cognitive performance and well-being. This sensor detects CO2 concentration by measuring infrared light absorption, with on-chip signal compensation from the built-in temperature and humidity sensor for reliable readings.
