MICS-5524 CO H2 CH4 Gas Sensor Detection Module

The MiCS-5524 Gas Sensor Module is a compact MEMS-based gas sensor designed for detecting carbon monoxide, hydrogen, methane, alcohol vapours and other combustible gases. It is commonly used for indoor air quality monitoring and gas-leak detection experiments.

This sensor outputs an analog voltage signal that changes according to the concentration of detected gas. It operates from a 5V DC supply, and the onboard heater element ensures stable sensing performance. The MiCS-5524 is ideal for hobby, learning and research projects using Arduino, ESP32, Raspberry Pi and other microcontrollers.

⚠ This sensor is not suitable for safety-critical applications and cannot identify which gas is detected — it only indicates the presence of one or more gases.

⭐ Gas Sensitivity Range

This sensor can respond to the following gases approximately:

• Carbon Monoxide (CO): ~1 to 1000 ppm

• Ammonia (NH₃): ~1 to 500 ppm

• Ethanol: ~10 to 500 ppm

• Hydrogen (H₂): ~1 to 1000 ppm

• Methane / Propane / Iso-Butane: ~1000+ ppm

(Calibration recommended for accurate measurement.)
