DFRobot Gravity H2S Sensor (Calibrated) - I2C & UART

• Gravity H2S Sensor (Calibrated) by DFRobot
• Supports three output modes: analog, I2C, and UART
• Offers high stability and high sensitivity
• Detects hydrogen sulfide concentration
• Strong anti-interference ability
• Detection Gas: Hydrogen sulfide (H2S)

The DFRobot Gravity H2S Sensor (Calibrated) - I2C & UART detects hydrogen sulfide concentration and supports three output modes: analog, I2C, and UART. The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of hydrogen sulfide in the environment. It can be widely used in the detection of hydrogen sulfide in industrial, underground, and environmental protection fields.

The probe adopts the electrochemical principle, has the characteristics of strong anti-interference ability, high stability, high sensitivity, etc., and the service life is as long as two years. The sensor has 32 modifiable I2C addresses, an integrated temperature compensation algorithm, and a threshold alarm function.

It has good compatibility with mainstream main control devices such as Arduino, ESP32, and Raspberry Pi. The easy-to-use Gravity interface, coupled with the sample code, can quickly build a hydrogen sulfide concentration detector.
