Car seat pressure sensor application case

The car seat sensor is a thin-film contact sensor. The contacts of the sensor are evenly distributed on the force-bearing surface of the seat, and a trigger signal is generated when the seat is subjected to external pressure. Used in car seat occupant perception systems, such as seat belt alarm sensors, automatic taxi fares, airbag sensing and driver departure, for example, with this device, it can sense whether there is a person in the seat, if there is no one, the airbag Will not open. When the driver leaves the seat, it will automatically return to neutral. It can design the shape of the sensor and the sensitivity of the contact according to the shape, hardness and tightness of the car seat.
