## Description

The Fermion MEMS Ethanol (EtOH) Gas Detection Sensor uses micro-electromechanical system (MEMS) technology for compact, low-power ethanol gas detection. With a detection range of 1–500 ppm, it provides qualitative measurement of ethanol concentration via an analogue voltage output. The MEMS design delivers a small footprint (13 × 13 × 2.5 mm), low power consumption (<20 mA), minimal heat generation, short preheating time, and fast response recovery. It operates at 3.3–5 V, making it compatible with Arduino and other common microcontrollers. Note: This sensor provides qualitative measurements only (detecting presence and relative concentration). For quantitative measurements, a factory-calibrated electrochemical sensor is required. Key Features MEMS Technology – Compact, low power, fast response and recovery 1–500 ppm Detection Range – Suitable for ethanol gas leak detection Analogue Voltage Output – Simple integration with any ADC-equipped microcontroller 3.3–5 V Operating Voltage – Arduino and Raspberry Pi compatible Low Power – Operating current <20 mA Long Lifespan – ≥5 years in air Specifications Gas Detected – Ethanol (EtOH) Detection Range – 1–500 ppm Operating Voltage – 3.3–5 V Operating Current – <20 mA Output Signal – Analogue voltage Sensitivity – R0(air) / Rs(150 ppm EtOH) ≥ 3 Operating Temperature – −10 to 50 °C Operating Humidity – 15–90% RH (non-condensing) Lifespan – ≥5 years (in air) Dimensions – 13 × 13 × 2.5 mm Precautions Remove the protective film before use Avoid exposure to volatile silicon compounds (silicone adhesive, hair gel, silicone rubber) Avoid high concentrations of corrosive gases (H₂S, SOx, Cl₂, HCl) Prevent contamination from alkalis, alkali metal salts, and halogens Avoid contact with water, condensation, or freezing conditions After extended storage, preheat for at least 24 hours before use Do not use in safety-critical or life-support systems Ideal For Breathalyser prototypes and alcohol detection Indoor air quality monitoring (VOC detection) Food quality and shelf-life assessment Ethanol gas leak detection Package Contents 1× Fermion MEMS Ethanol (EtOH) Gas Sensor (breakout) 1× 2.54 mm pitch header pin Resources Product Wiki (DFRobot)
