Product Description
The DFRobot Fermion: MEMS Multi-Gas Detector - CO/CH4/Ethanol Sensor (1-1000ppm, Breakout) is a compact gas sensor module built around the MiCS-5524 MEMS sensing element. The module provides a 0-5V analog output and is intended for detection of multiple combustible and hazardous gases, including carbon monoxide, methane, and ethanol. It operates from 5V DC with a stated power consumption of approximately 0.45W.
This module is suitable for industrial and laboratory monitoring tasks where simple analog interfacing to microcontrollers, data acquisition systems, or PLC-adjacent electronics is required. According to the source data, the module covers 1-1000ppm for CO, 10-500ppm for ethanol, and concentrations above 1000ppm for CH4. Hydrogen, ammonia, and hydrogen sulfide are also listed in the source material. Due to the sensing principle and cross-sensitivity of multi-gas semiconductor sensors, the module should be treated as a detector element that requires application-specific calibration.
