OPS (Seat Occupancy Sensor) is a piezoresistive sensor that determines whether a seat is occupied or not by sensing changes in surface pressure. It can set thresholds and filters to avoid jolts and false triggering by objects. OPS features high sensitivity and anti-interference design, fast response, low power consumption, and ease of integration (supporting multiple interfaces and protocols).

It is widely used in automotive safety systems (such as controlling airbags and reminding about seat belts), motorcycle safety systems (preventing accidental throttle control during riding), seat monitoring in offices and public places (for statistics and optimizing space utilization), and smart home scenarios (smart toilets, sofa-linked lights/accommodation) and so on.
