Collision Detector

Published on 18 Apr 2022. Written by Jagmohan

As per a survey, nearly 1.2 million people die in road accidents every year. In this project you will use piezoelectric sensor to detect collision. Then, system will send an SMS to any nearby hospital. The SMS will contain the location of the victim and personal details. As soon as they receive the SMS, they will send the AMBULANCE.

By implementing this project, you will try to save some lives. You will use Arduino UNO as the brain of the system. A GPS module to get the exact coordinates of the place of impact. A GSM module to send the SMS to the nearest hospital.

You will place the whole setup on a two-tyre vehicle. The system will run on the battery of vehicle, by use of voltage regulator. Test the project in controlled and safe environment. Kindly do not take any kind of risk to test this project.

Project implementation:

Piezoelectric sensor: It converts mechanical energy into electrical energy. It is made up of substrates such as quartz crystal. Also, ceramics are used such as zinc oxide. You will use it as the input of the system.

GSM module: Nowadays, almost every mobile phone contains an in-build GSM module. It allows the user to make calls and send SMS. In this project, you will use it to send an SMS in case of an impact.

GPS module: It records the exact coordinates of vehicle. These coordinates will be send to the hospital. This will make it easier for the ambulance to find the victim. It needs minimum 4 satellites to give accurate location.

Arduino UNO: It is a microcontroller board that contains ATMEGA328P IC. You will interface the piezoelectric sensor, GSM module and GPS module with it. It contains 6 analog pins and 14 digital pins. A 16 MHz quartz crystal provides clock pulses. It can run one operation at a time. You will use Arduino IDE to program your Arduino UNO.

Arduino IDE: It is an open-source Arduino environment. It allows the user to program the Arduino board for a specific operation. It uses C++ as the programming language. It contains many libraries that includes almost all the sensors available.

Project implementation:

1. Use single pin wires to interface the piezoelectric sensor to the Arduino UNO.
2. Interface the GSM module and the GPS module with the Arduino UNO.
3. Type the code for reading the input by the piezoelectric sensor.
4. Type the code for detecting the exact coordinates using GPS module.
5. Type the code for sending an SMS in case of collision, using GSM module.
6. Place the whole setup on a two tyre vehicle.
7. Provide some impact to test the project.
8. Verify the location sent as an SMS.
