Ultrasonic range finder using 8051 datasheet


Mar 30, 2017 · Here we are using a high precision HCSR-04 ultrasonic sensor module for the arduino based distance measurement. HC-SR04 ultrasonic sensor. An hc sr04 ultrasonic module is a non-contact range measuring device consist of an ultrasonic transceiver unit (transmitter and receiver section) and a control circuit. Aug 12, 2014 · Interfacing HC-SR04 Ultrasonic Distance Sensor with PIC Microcontroller PIC 16F877A is the heart of this circuit. VDD and VSS of PIC Microcontroller is connected to +5V and GND respectively which will provide necessary power for its operation. This article explains you how to measure the distance using 8051 microcontroller. This ultrasonic range finder system measures the distance up to 2.5 meters at accuracy of 1 cm. Circuit Principle: Generally, the distance can be measured using pulse echo and phase measurement method. Here, the distance can be measured using pulse echo method. system using the speed of sound in the medium. The measured distance is then displayed using a Sharp® Memory LCD BoosterPack Plug-in Module in inches with an accuracy of ±1 inch. The minimum distance that this system can measure is 6 inches and is limited by the ultrasonic transmitter’s settling-time. Dec 10, 2017 · Ultrasonic range finder using 8051 mictrocontroller has been already published by me in this website. This time it is an ultrasonic range finder using arduino. HC-SR04 ultrasonic range finder module is used as the sensor here. The display consists of a three digit multiplexed seven segment display.
