The Fermion MEMS Carbon Monoxide Sensor uses micro-electromechanical system (MEMS) technology to detect CO gas concentrations from 5 to 5,000 ppm. Its compact size, low power consumption, short preheat time, and fast response make it well suited for carbon monoxide leak alarms and portable CO detectors.

The sensor outputs an analogue voltage proportional to CO concentration and operates at 3.3–5V, making it easy to interface with Arduino and other microcontrollers.
