Product Overview
The S-H2S-01 is an H2S sensor module designed for low-power IoT applications. It features a sleep-type design, an intelligent algorithm for improved environmental adaptability, accurate detection, and a stable zero point. The sensor offers good resistance to toxicity, a long lifespan of up to 5 years or more, and a new micro-circuit design for strong anti-electromagnetic interference. It provides fast response and return-to-zero times, plug-and-play functionality, and independent digital output for temperature and humidity. This module is the smallest and lowest power consumption in the electrochemical field, and is RoHS Compliant.
