Introduction

The S-H2S-01 sensor module uses a sensor chip imported from Germany to measure hydrogen sulfide concentration, air temperature, and humidity. It outputs data via RS485 Modbus RTU protocol with fast response time, anti-interference technology, and supports accuracy calibration. The device is powered by 5V DC and can be easily integrated into larger systems without complex installation. Solid polymer electrochemical technology is an innovative gas detection method based on electrochemical catalytic reactions, generating electrical signals proportional to gas concentration. The sensor module consists of three catalytic electrodes, a solid electrolyte, and gas diffusion apertures. Gas reaches the working electrode through the diffusion apertures, where electrochemical redox reactions occur on the porous micro-surface of the electrode. The solid electrolyte conducts electron transfer, and the resulting current signal characterizes the gas concentration.
