SEN0678

SEN0678 is a Gravity: STCC4 True Carbon Dioxide (CO2) sensor. This 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 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 5,000ppm and an accuracy of ±[100ppm + 10%]), ambient temperature, and humidity data. 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.

• Unmatched cost-effectiveness for scalable IoT networks
• 3-in-1 sensing with automatic compensation
• Seamless integration and plug-and-play design
• Low power consumption: suitable for battery-powered or always-on systems
• High measurement accuracy: based on the TC principle for stable and reliable data
• Compact size: easy to integrate into space-constrained and modular design
• Digital output: I2C interface with strong anti-interference capability
• Operating on a wide 3.3V to 5V voltage range
• Communicating via a standard I2C interface eliminates complex wiring and soldering
• Response time is 20s
