Fermion MEMS Odor Gas Detection Sensor Module – H2S Ethanol Acetone 0.5–50ppm

The Fermion MEMS Odor/Smell Gas Detection Sensor is a high-precision, ultra-compact module designed for detecting environmental pollutants and odors including Hydrogen Sulfide (H2S), Ethanol (EtOH), and Acetone. Leveraging advanced MEMS (Micro-Electro-Mechanical System) technology, it offers a tiny 13×13 mm footprint, low power consumption under 20 mA, and a lifespan exceeding 5 years in clean air. With a simple 3-pin analog interface, it integrates seamlessly with Arduino, ESP32, Raspberry Pi, and other microcontrollers — ideal for portable detectors, smart home air quality systems, and industrial gas monitoring.
