SEN0678 · DFRobot
The Gravity: STCC4 Carbon Dioxide (CO2) Sensor is a highly accessible, 3-in-1 environmental monitoring module designed for rapid integration. Utilizing the Thermal Conductivity (TC) measurement principle, it delivers stable CO2 concentration readings (400 to 5,000 ppm) alongside precise ambient temperature and humidity data via an integrated SHT40 sensor.
