Gravity: MICS-4514 MEMS Gas Concentration Detection Sensor
SKU: SEN0377
This MEMS gas concentration sensor supports 3.3 V / 5 V systems and can detect multiple gases, including CO, C₂H₅OH (alcohol), H₂, NO₂, and NH₃. The onboard processing integrates gas-specific conversion formulas, allowing direct output of concentration values without complex calibration. With I²C communication and a wide 3.3–5.5 V input range, the sensor is fully compatible with Arduino, ESP32, Raspberry Pi, and other mainstream controllers, making it suitable for environmental monitoring, air-quality assessment, and IoT applications.
