Design and Development of Microcontroller based Distance Meter using Ultrasonic Sensors
Abstract
In the modern industrial life, different devices are manufactured for different purposes. But we have implemented a low cost distance meter using ultrasonic sensors. This suggested device uses commonly available ultrasonic sensor to measure the distance from the solid object of one to one and a half meters. This system is implemented on AT89C2051 microcontroller, name of specified locations are programmed on microcontroller. In this circuit, the microcontroller 89C2051 emits a series of pulses to the transmitter part of the transducer pair. The receiver part of transducer pair captures the signal which is reflected from the object that we desire to measure the distance. After processing the captured signal, the 89C2051 calculates the distance between the object and transducer pair by using the time of flight of ultrasonic signal and the distance is displayed on seven segment displays. This system is designed for a battery-powered model. This design is focused on low power consumption, small in size, lighter in weight, less time consuming process and easy manipulation.
