ultrasonic sensor using distance measurements mini project pdf
Everyone uses arduino uno or mega to make projects as they are easy to use and the code for arduino is easily available on the arduino forums and no one uses atmel,philips or other microcontroller to make such projects as the coding is somewhat difficult . In this project of mine i have used philips nxp microcontroller and embedded c language to write the code and this is my first contribution to instructables. The total cost of the project was under 25$.
A simple distance measurement and obstacle detection using NXP 89v51rd2fn and ultrasonic sensor HC-SR04 is presented in this article. This ultrasonic rangefinder can measure distances up to 4.0 meters at an accuracy of 1 centimeter. NXP89v51rd2 microcontroller and the ultrasonic transducer module HC-SR04 forms the basis of this circuit. The ultrasonic module sends a signal to the object, then picks up its echo and outputs a wave form whose time period is proportional to the distance. The microcontroller accepts this signal, performs necessary processing and displays the corresponding distance on the 16x2 lcd display. This circuit finds a lot of application in projects like automotive parking sensors, obstacle warning systems, terrain monitoring robots, industrial distance measurements etc.
Ultrasonic sensors are great tools to measure distance without actual contact and used at several places like water level measurement, distance measurement etc. This is an efficient way to measure small distances precisely. In this project we have used an Ultrasonic Sensor to determine the distance of an obstacle from the sensor. Basic principal of ultrasonic distance measurement is based on ECHO. When sound waves are transmitted in environment then waves are return back to origin as ECHO after striking on the obstacle. So we only need to calculate the travelling time of both sounds means outgoing time and returning time to origin after striking on the obstacle. As speed of the sound is known to us, after some calculation we can calculate the distance.

Ultrasonic Sensor Module
Ultrasonic sensor HC-SR04 is used here to measure distance in range of 2cm-400cm with accuracy of 3mm. The sensor module consists of ultrasonic transmitter, receiver and the control circuit. The working principle of ultrasonic sensor is as follows:
High level signal is sent for 10us using Trigger.
The module sends eight 40 KHz signals automatically, and then detects whether pulse is received or not.
If the signal is received, then it is through high level. The time of high duration is the time gap between sending and receiving the signal.
Ultrasonic range finder using 8051 .
A simple ultrasonic range finder using 8051 microcontroller is presented in this article. This ultrasonic rangefinder can measure distances up to 2.5 meters at an accuracy of 1 centi meter. AT89s51 microcontroller and the ultrasonic transducer module HC-SR04 forms the basis of this circuit. The ultrasonic module sends a signal to the object, then picks up its echo and outputs a wave form whose time period is proportional to the distance. The microcontroller accepts this signal, performs necessary processing and displays the corresponding distance on the 3 digit seven segment display. This circuit finds a lot of application in projects like automotive parking sensors, obstacle warning systems, terrain monitoring robots, industrial distance measurements etc.
HC-SR04 ultrasonic module.
HC-SR04 is an ultrasonic ranging module designed for embedded system projects like this. It has a resolution of 0.3cm and the ranging distance is from 2cm to 500cm. It operates from a 5V DC supply and the standby current is less than 2mA. The module transmits an ultrasonic signal, picks up its echo, measures the time elapsed between the two events and outputs a waveform whose high time is modulated by the measured time which is proportional to the distance.
This report details the implementation of distance measurement system using ultrasonic waves. As the human ear audible range is in between 20 Hz to 20 kHz, it is insensitive to ultrasonic waves that falls beyond that range, and hence, the ultrasound waves can be used for applications in industries or vehicles without hindering human activity.
They are widely used as range meters and proximity detectors in industries and also in the parking assistance systems. The distance can be measured using pulse-echo and phase-measurement method. In this project, the pulse-echo method is used. The measurement unit uses pulses over continuous signal in the transmission frequency range of ultrasonic transducers. The signal is transmitted by an ultrasonic transducer, reflected by an obstacle and received by another transducer wherein the signal is detected. The time delay of the transmitted and the received signal corresponds to the distance between the system and the obstacle.
The techniques of distance measurement using ultrasonic in air include continuous-wave and pulse-echo technique. In the pulse-echo method, a burst of pulses is sent through the transmission medium and is reflected by an object kept at a specified distance. The time taken for the pulse to propagate from the transmitter to the receiver is proportional to the distance of the object.
In this project, an ultrasonic module is interfaced to the microcontroller, and an ultrasonic transducer comprising of a transmitter and receiver are also used. The transmitted waves are reflected back from the object and received by the transducer. The total time taken from sending the waves to the receiving end is calculated by taking into consideration the velocity of the sound. Then, the distance is calculated by a program running on the microcontroller and displayed on an LCD screen interfaced to the microcontroller.
The power supply consists of a step-down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter, and it is then regulated to +5V using a voltage regulator 7805, which is required for the operation of the microcontroller and other components.
