We have designed and constructed a vehicular detector. The detector sensing mechanism is based on the ultrasonic waves at frequency 42 kHz. The detector counts and classifies the passing vehicles of the lane over which it is fixed and mounted. The ultrasonic sensor emits ultrasonic pulses and receives the scattered waves from the ceiling of moving vehicles. Classification is done according to the vehicle’s height. Three classes are identified: normal vehicle, van and bus/trailer. Signals of the reflected waves are detected and then analysed by an electronic hardware. The output data are transmitted on a wireless basis to a neighbouring PC on the ground with the help of two radio modules
