DFRobot Fermion MEMS VOC Gas Sensor Module 1–500ppm – Ethanol Formaldehyde Toluene

The DFRobot Fermion MEMS VOC Gas Sensor is a state-of-the-art detection module designed for qualitative monitoring of Volatile Organic Compounds (VOCs) including Ethanol, Formaldehyde, and Toluene. Utilizing advanced MEMS technology, it delivers high sensitivity across a 1–500 ppm range in an ultra-compact 13×13 mm footprint with low heat generation, rapid preheating, and a lifespan of ≥5 years in normal air conditions. Operating at under 20 mA, it is ideal for battery-powered environmental monitors, indoor air quality systems, industrial safety, and health tech applications.
