Description

MEMS VOC (Volatile Organic Compounds) sensors are micro-electromechanical systems designed to detect the presence of volatile organic compounds in the air. These sensors are small, highly sensitive, and often used in applications such as air quality monitoring, environmental sensing, and indoor air quality control.

VOCs-4 is a miniature metal oxide semiconductor gas sensor based on MEMS micro hotplate technology for detection a wide rang of VOCs gas in air. Sensor production combined with silicon substrate MEMS technology, thin film technology, thick film technology and ceramic packaging technology. The gas sensitive layer is deposited at the top of the hotplate and interdigitated electrodes, resulting in a conductivity dependent on the concentration of harmful gases.
