## Description

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. Key Features MEMS Technology – Compact, low-power, fast response and recovery 5–5,000 ppm Range – Qualitative CO concentration measurement Analogue Output – Simple voltage-based reading 3.3–5V Operation – Compatible with Arduino, ESP32, Raspberry Pi, etc. Ultra-Compact – Just 13 × 13 × 2.5 mm Low Power – <20 mA operating current Long Lifespan – ≥5 years in air Specifications Gas Detected – CO (Carbon Monoxide) Detection Range – 5–5,000 ppm Operating Voltage – 3.3–5V Operating Current – <20 mA Output Signal – Analogue voltage Sensitivity – R₀ (air) / Rs (150 ppm CO) ≥ 3 Operating Temperature – -10°C to 50°C Operating Humidity – 15–90% RH (non-condensing) Dimensions – 13 × 13 × 2.5 mm Warning: This sensor provides qualitative measurements only. Do not use it in systems involving personal safety. Avoid exposure to volatile silicon compounds, corrosive gases, alkalis, and prolonged extreme environments. Remove the protective film before use. After extended storage, preheat for at least 24 hours. Ideal For Carbon monoxide leak alarms Portable CO detectors Industrial CO monitoring Environmental air quality projects Package Contents 1× Fermion MEMS Carbon Monoxide CO Sensor (Breakout) 1× 2.54 mm pitch header pin Resources Product Wiki
