DFRobot Gravity SO2 sulphur dioxide sensor I2C and UART

The Gravity SO2 Sulfur Dioxide Sensor is a high-precision instrument based on electrochemical principles, designed to measure the SO2 concentration in the air. With a measurement range of 0-20 ppm, this sensor is ideal for environmental monitoring, industrial applications, and air quality assessment. The sensor is factory calibrated, allowing for quick and accurate measurements. Thanks to support for I2C and UART outputs, the sensor can be easily integrated into existing systems. Its robust design and long lifespan of over two years make it a reliable tool for continuous measurements. With its high stability and sensitivity, the sensor offers strong anti-interference capabilities against other gases.

Features:

• High precision and fast response time.
