Ultrasonic Radar using Pi

Published on 20 May 2022. Written by Naveen Lakkundi

Ultrasonic sensor is used as a range finder or a distance calculator, It generates sound waves and waits for the echo and depending on the timing of the echo It calculates the distance between the sensor and the object. In this project you will be using the ultrasonic sensor to find the objects coming in the range, this project is somewhat similar to the radar, so the utrasonic sensor constantly sends sound pulses and if the sound waves are received back then there is aobject in in front of the sensor. You can create a GUI to show the area of the coverage of the sensor and if there is any object infront of the sensor you can also show the position of the object.

Project Description:

Raspberry Pi 3 B: Raspberry Pi is a Microprocessor which has 40 pins with 27 GPIO pins, it has a 1 Giga Bytes of RAM and a SD card slot for the storage or the ROM,it can be used as a mini computer for low computing operations, it has a dual band LAN, faster Ethernet, Bluetooth, it also has USB and HDMI ports for connecting devices. This device can be used as a server which we are doing in this project.
Micro SD card: You will need a minimum of 8 gigabytes SD card for this project, this SD card is used as the ROM of the raspberry pi. Use 32 Gigabyte or 64 Gigabytes of
Display: You can use any kind of display for the project, like monitors, TV or any size display that fits your requirement to configure the Pi.
Power Supply: Raspberry Pi needs a power supply of 5V and 2A Micro USB type.
Mouse and keyboard: You will need this to control, monitor, and to configure the Pi.
Ultrasonic sensor: Ultrasonic sensor is device which can measure the distance of an object by using sound waves. This sensor has a transmitter and a receiver that sends and receives only ultrasonic sound waves, the sound wave of a particular frequency is used by this device.
Stepper Motor Stepper motors or the stepping motors are brushless DC motors which divides ful rotation into equal different steps. The motor's position can then be commanded to move and hold at one of these steps without any position sensor or feedback

Project Implementation:

Install the Raspbian OS into the SD card, and boot the Raspberry Pi.
Connect your Display with the HDMI cable. Plug in the keyboard and mouse to navigate and configure the raspberry pi.
Write a Python program with which you can find the objects in front of the sensor and also the distance between the object and the sensor.
The object in the range also should be ploted so that the distance and the exact position of the object can be seen in the plot or the range of the ultrasonic range finder or the radar.
The stepper motor also should sweep the area to be scanned for the obstacles coming in the range, and then it should be plotted to keep track of the obstacle in the range.

Project Brief:The Raspberry Pi when configured and all the required software has been installed then the Pi is ready to be used as a Ultrasonic range finder.

Software requirements:

Raspbian OS(Debian Linux): Raspbian operating systems are based on Linux, Raspberry pi are also compatible with Windows and IOS but prefer any Linux based OS, Raspbmc is an XBMC based open source Media center where yu can convert your raspberry pi to a TV.
Python IDE 3: Python IDE 3 is compiler where you can write and compile python program.

Programing Language:

Linux (terminal commands)
Python
