DISTANCE MEASUREMENT USING ULTRASONIC SENSOR AND FPGA

Abstract: Navigation of an object is widely used for target detection. In such systems the nearest objects are detected by distance measurement. The distance measured and choice of sensor depends on type of application and also surrounding environmental issues like temperature, humidity, fog etc. For short distance measurement ultrasonic sensor is used. The ultrasonic sensor output is used to measure the distance. The computation, processing, control and display units are implemented on FPGA. The Xilinx synthesis tool is used for implementing the design on FPGA. FPGAs have faster processing capability, low power consumption and are easily reconfigurable for the necessary applications. The measured distance is displayed on segment displays.
