The Design of Speed Detector Based on Wireless Sensor Network

An ultrasound velocimetry system based on single-chip CC2530 was designed, this combined the transit-time velocimetry and Doppler velocimetry, achieving the monitoring of wireless sensor network to the speed of the car. The Proteus software simulates the hardware circuits of the ultrasonic transmitter and receiver module. An ultrasound velocimetry system measures high-speed by the ultrasonic Doppler principle, it measures low-speed through the transit-time principle, the speedometer system was verified by the simulation technology. The design has a low complexity, low power, low cost, small error, application and so on.
