MICS6814 Multi-Gas Sensor Module — CO, NO2, NH3 Detection
The MICS6814 is a compact multi-gas sensor from SGX Sensortech that simultaneously detects three different gases: Carbon Monoxide (CO), Nitrogen Dioxide (NO2), and Ammonia (NH3). It contains three independent sensing elements on a single chip, each with its own analog output — making it ideal for comprehensive air quality monitoring, industrial safety, and smart city applications with Arduino or ESP32.
