Gravity: Factory Calibrated Electrochemical Sulfur Dioxide (SO2) Sensor
The Gravity: Factory Calibrated Electrochemical SO2 Sensor is a high-accuracy gas detection module designed for reliable measurement of sulfur dioxide (SO2) concentration in industrial and environmental monitoring applications. Featuring a factory-calibrated electrochemical probe, the sensor enables fast deployment and precise readings without complex calibration procedures. It supports three output modes – Analog, I2C and UART, ensuring flexible integration with popular development platforms such as Arduino, ESP32 and Raspberry Pi. With excellent anti-interference capability, high sensitivity and strong long-term stability, this sensor is well suited for continuous monitoring in challenging environments.
The sensor incorporates an integrated temperature compensation algorithm, configurable threshold alarm function and 32 selectable I2C addresses, making it ideal for intelligent, multi-sensor systems. With a service life of up to two years, it offers dependable performance for industrial safety systems, environmental protection equipment and air quality monitoring solutions. The Gravity plug-and-play interface, along with ready-to-use sample code, allows developers to quickly build a robust sulfur dioxide detection system with minimal effort.
