Ignition System Using Fingerprint And Alcohol Sensor

Step-by-Step Guide:Ignition System Using Fingerprint

Introduction

In this article, we will Explain how to create a bike ignition system using the Fingerprint R307 sensor, And MQ3 Alcohol sensor, With Arduino. This system Controls the car or bike irrigation system if the fingerprint will match then the iration system will start otherwise is not start.

Overview

  • The project aims to protect the bike and cars to avoid accidents.
  • This Project is soo many features, the system Will ensure that only authorized users who have valid fingerprints and are not Drink alcohol can start the bike.
  • The project is various hardware and software components included in making the project. The hardware components are Arduino Nano, an R-307 fingerprint sensor module, an MQ-3 alcohol sensor, a 5v one-channel relay module, LEDs, and Push buttons.
  • The Arduino Nano board controller and the R-307 fingerprint sensor module captures and verifies fingerprints. The MQ-3 alcohol sensor Find out the alcohol in the vicinity of the bike.

Fingerprint R307 Sensor

  • VCC: Connect 5V to the Arduino.
  • GND: Connect to GND to the Arduino.
  • RX: Connect digital pin 2 to the Arduino.
  • TX: Connect digital pin 3 to the Arduino.
  • INT: Not connected.
  • RST: Not connected.

MQ3 Alcohol Sensor

  • VCC: Connect 5V to the Arduino.
  • GND: Connect to GND to the Arduino.
  • AO: Connect analog input A0 to the Arduino.
  • DO: Not used in the provided code.

16×2 LCD Display with I2C

  • Connect the I2C data (SDA) and clock (SCL) lines to the corresponding A4 and A5 pins on the Arduino Nano board.
  • The I2C backpack usually includes pull-up resistors, so external resistors are not required.

Other Components

  • Connect the pins enroll Push Button (4), delPush Button (5), up Push Button(6), down Push Button(7), openLed(8), closeLed (9), redled (10), relay Module (11), and Alcohol Sensor (A0) to the respective digital and analog pins on the Arduino Nano board.
