With a detection range of 1–500 ppm, it provides qualitative measurement of ethanol concentration via an analogue voltage output.\n\nThe 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.\n\n\nNote: This sensor provides qualitative measurements only (detecting presence and relative concentration). For quantitative measurements, a factory-calibrated electrochemical sensor is required.\n\n\nKey Features\n\n\nMEMS Technology – Compact, low power, fast response and recovery\n\n1–500 ppm Detection Range – Suitable for ethanol gas leak detection\n\nAnalogue Voltage Output – Simple integration with any ADC-equipped microcontroller\n\n3.3–5 V Operating Voltage – Arduino and Raspberry Pi compatible\n\nLow Power – Operating current <20 mA\n\nLong Lifespan – ≥5 years in air\n\n\nSpecifications\n\n\nGas Detected – Ethanol (EtOH)\n\nDetection Range – 1–500 ppm\n\nOperating Voltage – 3.3–5 V\n\nOperating Current – <20 mA\n\nOutput Signal – Analogue voltage\n\nSensitivity – R0(air) / Rs(150 ppm EtOH) ≥ 3\n\nOperating Temperature – −10 to 50 °C\n\nOperating Humidity – 15–90% RH (non-condensing)\n\nLifespan – ≥5 years (in air)\n\nDimensions – 13 × 13 × 2.5 mm\n\n\nPrecautions\n\nRemove the protective film before use\nAvoid exposure to volatile silicon compounds (silicone adhesive, hair gel, silicone rubber)\nAvoid high concentrations of corrosive gases (H₂S, SOx, Cl₂, HCl)\nPrevent contamination from alkalis, alkali metal salts, and halogens\nAvoid contact with water, condensation, or freezing conditions\nAfter extended storage, preheat for at least 24 hours before use\nDo not use in safety-critical or life-support systems\n\n\nIdeal For\n\nBreathalyser prototypes and alcohol detection\nIndoor air quality monitoring (VOC detection)\nFood quality and shelf-life assessment\nEthanol gas leak detection\n\n\nPackage Contents\n\n1× Fermion MEMS Ethanol (EtOH) Gas Sensor (breakout)\n1× 2.54 mm pitch header pin\n\n\nResources\n\nProduct Wiki (DFRobot)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1485,"title":"Default Title","sku":"DF-SEN0569","price":7.8,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":231,"option1":"Default Title"}]}
