Product Introduction

Vmanx child safety seat sensor is a membrane contact sensor.Sensor contacts are evenly distributed on the force receiving surface of the seat, and trigger signals are generated when external forces an external force acts on the seat. It can be applied to the child safety seat occupant perception system to prevent children from being forgotten in the car, avoid unexpected accidents etc. For example, with this device, the pressure sensor can detect whether the child is riding on it, and the signal of the sensor is detected by MCU. Then, MCU control can send signals to mobile phones or automotive related terminals as a reminder to prevent unexpected discoveries. It can also design the size of the sensor and the sensitivity of the contacts according to the shape and hardness of the seat.
