MICS-4514 Air Quality Gas Sensor Module - CO, NO2, NH3, CH4 Concentration Detection, 5V Dual Channel Analog Output for MCU Development
- [Advanced Dual-Sensor Technology] Equipped with the highly sensitive MICS-4514 chip, which integrates two independent sensing elements on one package. Designed to detect both reducing gases (like Carbon Monoxide) and oxidizing gases (like Nitrogen Dioxide) simultaneously.
- [Comprehensive Gas Detection] Highly responsive to a wide range of hazardous and environmental gases, including CO (1-1000ppm), NO2 (0.05-10ppm), NH3 (Ammonia), CH4 (Methane), and Ethanol. Ideal for indoor air quality monitoring.
- [Universal MCU Compatibility] Operates on a standard 5V DC power supply. Outputs dual-channel analog voltage signals (AOUT1 / AOUT2) that can be easily read by the ADC (Analog-to-Digital Converter) of any 8-bit or 32-bit Microcontroller (MCU, 8051, ARM, PIC).
- [Rapid Response & Stability] Features a built-in heating element to maintain optimum sensing temperature. Delivers fast response times, high sensitivity, and excellent long-term stability for continuous environmental monitoring projects.
- [Broad Application Scenarios] The perfect electronic component for DIY smart home ventilation systems, industrial leak detection alarms, air purifier upgrades, and environmental science engineering projects.

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.
