MICS-4514 Air Quality Gas Sensor Module - CO, NO2, NH3, CH4 Concentration Detection, 5V Dual Channel Analog Output for MCU Development

Professional MICS-4514 Gas Sensor Module for Air Quality Monitoring

Build highly reliable environmental monitoring systems with this compact MICS-4514 Gas Sensor Module.this sensor provides precise concentration detection of various toxic and flammable gases in the atmosphere.

Dual-Channel Detection Capability

the MICS-4514 features a dual-sensor architecture:

• Sensor 1 (RED): Optimized for reducing gases such as Carbon Monoxide (CO), Hydrogen (H2), Ammonia (NH3), Methane (CH4), and Ethanol.
• Sensor 2 (OX): Specifically optimized for oxidizing gases, primarily Nitrogen Dioxide (NO2).

Easy Hardware Integration

The module is mounted on a durable PCB with standard pin headers. By supplying a steady 5V DC, the module outputs analog voltage signals proportional to the gas concentration, making it exceptionally easy to integrate with the ADC pins of your custom development board.
