Vehicle Accident Alert System Using Arduino


In This, Article You Learn How To Interface with The ADXL-335 Sensor With Arduino And I will Show you how you Clabite The ADXL-335 sensor.

ADXL-335 An accelerometer is an electromechanical device that will measure acceleration forces in the form of  The Analog Value And provide output In the Form Of X, Y, And Z directions. with the help of all directions, you create so many Projects.

ADXL-335 Sensor

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.

Block Diagram

Here I Show The Block Diagram In this Project, On the Input Side I connected to the ADXL-335 Sensor and on the Output Side, I connected To The GSM Sim800l And GPS Neo-6m Module.

If any Movement is detected The ADXL-335 Sensor Crosses the Threshold Value And GSM Send The Text Message.

Circuit Diagram

Now I will Explain the Pin Whare I connected all components, the ADXL-335 Sensor IS connected To The Pin Number:-

  • VCC         5v 
  • GND        GND
  • X-Axis      A0
  • Y-Axis      A1
  • Z-Axis      A2

GSM SI800l Module Will be connected To The Pin Number:-

  • VCC      3.7v
  • GND     GND
  • Tx         D2
  • Rx         D3

GPS Neo-6m Module Will be connected To The Pin Number:-

  • VCC        5v
  • GND      GND
  • Tx         D10
  • Rx         D11
