## Description

A compact MEMS gas sensor breakout based on the MiCS-5524, capable of detecting concentrations of multiple gases including carbon monoxide (CO), methane (CH4), ethanol (C2H5OH), propane (C3H8), butane (C4H10), hydrogen (H2), hydrogen sulfide (H2S), and ammonia (NH3). The breakout provides analog voltage output and includes a power enable/disable pin for low-power applications. Compatible with 3.3–5.5 V controllers, with sample code that integrates concentration conversion formulas for each supported gas. Key Features Multi-Gas Detection – CO, CH4, C2H5OH, C3H8, C4H10, H2, H2S, and NH3 MEMS Technology – Compact, reliable sensing element Low Power Mode – Enable/disable pin for power management Analog Output – Simple integration with any microcontroller ADC 3.3–5.5 V Compatible – Works with a wide range of controllers Built-In Formulas – Sample code includes gas concentration calculations Specifications Sensor: MiCS-5524 Operating Voltage: 4.9–5.1 V DC Power Dissipation: 0.45 W Output: Analog voltage Measuring Ranges: CO: 1–1000 ppm C2H5OH: 10–500 ppm H2: 1–1000 ppm NH3: 1–500 ppm CH4: >1000 ppm Operating Temperature: −30 °C to 85 °C Operating Humidity: 5–95% RH (no condensation) Lifespan: >2 years (in air) Board Size: 12 × 16 mm Mounting Holes: 2 mm inner / 4 mm outer diameter Ideal For Gas leak detection systems Air quality monitoring Gas safety equipment Environmental sensing projects Package Contents 1× Fermion MEMS Gas Sensor – MiCS-5524 Breakout 1× 3-Pin Black Header Resources Product Wiki MiCS-5524 Datasheet (PDF) Schematic (PDF) Dimensions & Component Layout (PDF)
