This document describes how to build a DIY parking sensor using an ultrasonic sensor, LED, and buzzer to detect minimum distances and warn drivers. The parking sensor is designed to measure distances with its ultrasonic sensor and light the LED and ring the buzzer when an object gets within 200cm to alert the user of a potential collision. It can be used to help prevent collisions while parking or in tight spaces.

3.  Develop our own DIY parking sensor, for
detecting minimum distances and warning
the driver of the car about it.

5.  LED
 Buzzer
 ultrasonic sensor
 jumper wires
 breadboard

6.  To check its working, try placing your hand or any
other object, with minimum distance of 200 cm. As
soon as you reach the minimum limit of distance, the
buzzer will ring and the LED will also light up. We can
use it for detecting collision, we can warn the user
that after this limit the collision may happen. We can
use it on parking places, as well as in the cars or
automobiles. Sensors can detect and prevent any sort
of collision with any object.
 We used the ultrasonic sensor that takes the distance
as input or as sensed by it and gives the output on
the serial monitor. We then used the led and buzzer
to warn the user that the limit of minimum distance
has been reached.
