Vehicle Accident Alert System With ADXL335 Sensor

INTRODUCTION

In this article, you learn how to design an Impout-based GPS tracking system. when the coordinates of the ADXL-335 sensor find out the impact and which side the car will impact.

If the impact crosses the threshold value, then the GSM is ready to send the text message with the GPS coordinates. The Accident location of sent in the form of a Google map link. derived from the latitude and longitude of the GPS Module.

COMPONENT

• Arduino Nano
• Sim 800l module
• GPS Neo 6M Module
• ADXL-335 Sentor
• LM2596 Step Down Converter

Arduino Nano

Here we used the Arduino Nano, which is a low-cost microcontroller and easy to available in any market Arduino Nano is built so many protocols like I2C, SPI, UART  I2C, and ADC The GSM module and GPS modules are connected to the UART Protocol require only four-wire, Rx, Tx, Vcc & GND.

Sim 800l Module

• The sim 800l GSM module is small & very low-cost
• The sim 800l  GSM module is operated in a very low voltage 3.7v to 4v power supply.

GPS Neo-6M Module

• The GPS Neo-6m Module works on UART Protocol and its operating voltage is 5v.
• The Module will connected to directly with Arduino nano microcontroller.

ADXL-335 Sentor

• This module can be used to sense motion (in the case of non-moving) in 3 axes. This is the latest in a long, proven line of Analog Sensors- the holy grail of accelerometers.

• The ADXl-335 Sensor work of ADC requires a total of 5 wires to be connected with the Arduino nano microcontroller.
• The Operating voltage is 5v and you directly attach it to the Arduino Nano Board.

LM2596 Step Down Converter

• LM2596 DC-DC Buck Converter Adjustable Step-Down Power Supply Module is this project we used the provide proper 3.7v to sim800l GSM Module.
