Adafruit MiCS5524 CO, Alcohol and VOC Gas Sensor Breakout
The Adafruit MiCS-5524 Gas Sensor Breakout is a robust MEMS sensor from SGX Sensortech for detecting carbon monoxide, natural gas leaks, alcohol, and volatile organic compounds (VOCs). It provides a simple analogue voltage output that increases in proportion to the concentration of detected gas — just power it at 5V and read the analogue pin.
The sensor is suitable for indoor air quality monitoring, breath checking, and early fire detection applications. Note that while it detects multiple gas types, it cannot differentiate between them.
Key Features
- Multi-Gas Detection – Sensitive to CO (~1–1000 ppm), Ammonia (~1–500 ppm), Ethanol (~10–500 ppm), H2 (~1–1000 ppm), and Methane/Propane/Iso-Butane (~1000+ ppm)
- Analogue Output – Voltage increases proportionally with detected gas concentration
- 5V Operation – Simple power and read interface
- Enable Pin – Pull high to power off the heater and conserve energy
- Low Heater Current – 25–35 mA when active
- MEMS Technology – Robust and compact sensor element
Ideal For
- Indoor air quality monitoring projects
- Gas leak detection experiments
- Educational sensor projects
- Environmental monitoring prototypes
Package Contents
- 1× Adafruit MiCS-5524 Gas Sensor Breakout (assembled and tested)
- 1× Header pin strip
