Hydrogen Sulfide (H2S) Sensor Module

The Hydrogen Sulfide (H₂S) sensor uses electrochemical sensing technology with a four-electrode design to detect and measure H₂S concentrations in ambient air. Hydrogen sulfide gas diffuses into the sensor and undergoes electrochemical oxidation at the sensing electrode, generating an electrical current proportional to the H₂S concentration. The additional electrodes compensate for environmental influences and help maintain measurement stability under varying ambient conditions. This signal is measured and converted into concentration values, enabling accurate real-time monitoring of hydrogen sulfide levels.
