PURPOSE: A vehicle height sensor device of PWM method, capable of simple design and wiring for vehicle height, is provided to reduce the connector pins of a controller by connecting the vehicle height sensing parts and controllers using one wire. CONSTITUTION: A vehicle height sensor device of PWM method comprises a vehicle height sensing part(1) and a controller(2). The vehicle height sensing part senses vehicle height and outputs to a PWM signal. The vehicle height sensing part is connected with an input port of the controller using one wire(3). The vehicle height sensing part comprises a plurality of PWM method vehicle height sensing parts. The controller receives the PWM signal of the vehicle height sensing part through one input port. The PWM signal comprises ID of vehicle height sensing part and a vehicle height sensing value. ID of vehicle height sensing part has the PWM signal pulse width, which is differently set in each vehicle height sensing part.
