Gravity SO2 Sulfur Dioxide Sensor I2C and UART

The Gravity SO2 Sulfur Dioxide Sensor is a highly precise instrument based on electrochemical principle, used for measuring SO2 concentration in the air. With a measurement range of 0-20ppm, this sensor is ideal for environmental monitoring, industrial applications and air quality monitoring. The sensor is factory calibrated, enabling fast and accurate measurement. Support for I2C and UART outputs makes it easy to integrate the sensor into existing systems. The robust construction and a long lifespan of over two years make it a reliable tool for continuous measurements. With its high stability and sensitivity, the sensor offers a strong anti-interference ability against other gases.
