When someone is sitting on a car seat, The car seat surface is subjected to a pressure, This pressure makes the upper and lower circuit layers of the seat sensor contact each other, Thus, the circuit loop is turned on conductive to generate a signal to other devices, Showing someone is sitting on the car seat, and other systems in the car will use this signal to work, For example, the seatbelt warning system will detect if the person on the car seat whether put a seat belt on himself.
