Gravity: H2S Sensor (Calibrated) - I2C & UART SF_Seismograph and general purpose input pinsThis is a sensor that 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. 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
