Product Description
Product Overview
The MiCS-4514 is a compact MOS sensor featuring two fully independent sensing elements within a single package. Designed as a robust MEMS sensor, it is specifically engineered for the detection of pollution from automobile exhausts. Its key advantages include the smallest footprint for compact designs (5 x 7 x 1.55 mm), suitability for harsh environments, and high-volume manufacturing for cost-effective applications with short lead-times. The sensor is capable of detecting Carbon monoxide (CO), Nitrogen dioxide (NO2), Ethanol (C2H5OH), Hydrogen (H2), Ammonia (NH3), and Methane (CH4).
