Nowadays, the number of vehicles is increasing significantly every year. Many accidents are occurring because of the alcohol consumption of the driver. After drinking alcohol, driving is the most reason for accidents in almost all countries all over the world. Therefore, alcohol detection system and automatic finding car accident place using GSM modem and GPS are presented in this paper. The combination purpose of alcohol detection and car accident detection systems is to save human life. If the car driver drinks alcohol, the alcohol sensor will sense alcohol concentration, will display it on the LCD and will turn off the car engine. In the accident detection system, the vibration sensor senses vibration when an accident occurs. If the sensor senses the car accident, the vibration sensor will give the digital output to the microcontroller. By using the GPS module, the latitude and longitude of the place where the accident happened are sent by message to the assigned phone number through the SIM900 GSM Modem. By implementation of this system, human beings can be protected from harm and other non-desirable outcomes on road accidents.
