Gravity: STCC4 True Carbon Dioxide (CO2) Sensor (3-in-1 Air Quality Monitoring, 400 ~ 5000ppm)
The Gravity: STCC4 Carbon Dioxide (CO2) Sensor is a highly cost-effective, multi-functional air quality monitoring module designed for rapid hardware integration and scalable deployments. Utilizing the Sensirion STCC4 high-performance gas sensing chip based on the Thermal Conductivity (TC) measurement principle, this sensor delivers stable and reliable CO2 concentration readings. Its standout feature is the combination of extreme affordability with 3-in-1 measurement capabilities, integrating an onboard SHT40 sensor to provide simultaneous CO2 (with a measurement range of 400 to 5,000 ppm and an accuracy of ±[100 ppm + 10%]), ambient temperature, and humidity data.
Operating on a wide 3.3V to 5V voltage range and communicating via a standard I2C interface, it eliminates complex wiring and soldering. This makes the module highly suitable for deploying multi-node indoor air quality monitoring networks, building automation systems, smart home setups, and educational STEM projects where budget constraints, compact size, and ease of use are primary considerations.
