Product Description
Product Overview
The MiCS-6814 is a compact MOS sensor featuring three independent sensing elements within a single package. Designed with a robust MEMS structure, it is ideal for detecting pollution from automobile exhausts and for agricultural and industrial odor monitoring. Its small footprint (5 x 7 x 1.55 mm) makes it suitable for compact designs, while its high-volume manufacturing ensures cost-effectiveness for large-scale applications. The sensor offers short lead times and is built for harsh environments.

Notes:
- 1. Sensing resistance in air R0 is measured under controlled ambient conditions.
- 2. Sensitivity factor for CO is defined as Rs in air divided by Rs at 60 ppm CO.
- 3. Sensitivity factor for NO2 is defined as Rs at 0.25 ppm NO2, divided by Rs in air.
- 4. Sensitivity factor for NH3 is defined as Rs in air divided by Rs at 1 ppm of NH3.
