Fermion: MEMS Ethanol EtOH Gas Detection Sensor (Breakout, 1-500ppm)

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
