P.Ramesh, Sai Sudheera, D.Vinay Reddy 03 2 The paper is designed to develop distance measurement system using ultrasonic waves and interfaced with arduino We know that human audible range is 20hz to 20khz We can utilize these frequency range waves through ultrasonic sensor HCSR04The advantages of this sensor when interfaced with arduino which is a control and sensing system a pro per distance measurement can be made with new techniques As large amounts are spent for hundreds of inflexible circuit boards the arduino will allow business to bring many more unique devices This distance measurement system can be widely used as range meters and as proximity detectors in industries The hardware part of ultrasonic sensor is interfaced with arduino This method of measurement is efficient way to measure small distances precisely The distance of an obstacle from the sensor is measured through ultrasonic sensor After knowing the speed of sound the distance can be calculated Designed to develop distance measurement system using ultrasonic waves and interfaced with arduino We know that human audible range is 20hz to 20khz We can utilize these frequency range waves through ultrasonic sensor HCSR04The advantages of this sensor when interfaced with arduino which is a control and sensing system a pro per distance measurement can be made with new techniques As large amounts are spent for hundreds of inflexible circuit boards the arduino will allow business to bring many more unique devices This distance measurement system can be widely used as range meters and as proximity detectors in industries The hardware part of ultrasonic sensor is interfaced with arduino This method of measurement is efficient way to measure small distances precisely The distance of an obstacle from the sensor is measured through ultrasonic sensor After knowing the speed of sound the distance can be calculated Copyright (c) World Journal of Pharmaceutical Seiences.
