detecting sensor in vehicle for safe driving system of vehicle for drunk and driving cases, which senses and detects alcohol particles and send messages if alcohol . In this process GSM and GPS modules are connected to microcontroller for controlling purpose . GPS module get the position of vehicle with longitude and latitude and it send message to authorized person. We have also provided the security system for vehicle that ensuring the driver is engaged the helmet
When the alcohol presence is detected by the system an SMS will be sent to the authorized person . The said SMS will be containing the current location of the driver
2. SYSTEM DESIGN System consists of force sensor, Alcohol detection part, GPS and GSM . Force is used to check whether the driver is engaged the seat belt or not . Alcohol detection will be done using MQ3 sensor. If the alcohol presence is detected the message containing current location will be sent to the family or friends
Key Words: Alcohol, Driver, Hazardous, GSM, GPS, Alcohol Sensor
1. INTRODUCTION
2.1 BLOCK DIAGRAM
This system senses the content of alcohol in breath. This system uses LCD display, MQ3 sensor, force sensor and GPS and GSM techniques. The output of the sensor is directly proportional to the content of alcohol consumed. This type of sensors in cars is a great safety factor which can be embedded in steering of the cars. When the driver starts the ignition, sensor detect the presence of the alcohol in his breath and if the alcohol detected then automatically it will stop the ignition of the car. Thus we can reduce accident rate due to drunk and drive. The system also check whether the driver is engaged the seat belt or not. By using GSM send a SMS to the authorized person. And by using GPS we can send the location of the vehicle at that instant. Hence the system reduces the road accidents and fatalities due to drunk driving in future. Microcontroller is the heart of our project. Microcontroller gets the coordinates from GPS modem and then it sends this information to user in text SMS through GSM.
A. Arduino ATMEGA328 ATmega328 Arduino Uno microcontroller board is used in the designed system. 14 pins are present in the unit, which allows outflow and inflow of feeding, a Universal Serial Bus port, 6 continuous signals with time changing quantity, an on-board voltage regulator, 16 Mega Hertz electronic oscillator, a power connector, ICSP header, and a reset button. The Atmega328 microcontroller has 32 Kilo Bytes flash memory, 1 Kilo Bytes EEPROM and 2 Kilo Bytes SRAM.
1.1 Alcohol Detection Alcohol consumption of the driver will be detected by using a MQ3 sensor. If driver consumed alcohol, then alcohol level inside the vehicle will be higher than a threshold value. When alcohol consumption detected, then the vehicle immediately stops to avoid risk of accident..
B. Alcohol MQ-3 Sensor Tin Dioxide (SnO2) sensitive layer is used to made sensor. Itis having less sensitivity to Benzene and more sensitivity to alcohol. It has a circuit with improved stability, good lifetime and quick response. Analog interface type design is used in the sensor. Sensor pins represents 1-output, 2- ground and 3-power supply. The
1.2 Seat Belt Detection Using the force sensor we will be detecting whether the seat belt is engaged or not. If the seat belt is not engaged the vehicle will fail to start .
