Alcohol detection system with vehicle tracking

Computer Engineering

Our proposed system would be repetitively monitoring the driver breath by placing it on the driver wheel or somewhere the drivers breath can be constantly monitored by it. So if a driver is drunk and tries to drive the system detects alcohol presence in his/her breathe and locks the engine so that the vehicle fails to start. And sends vehicle details to the owner In another case if the driver is not drunk while he starts the vehicle and engine is started but he/she drinks while driving the sensor still detects alcohol in his breath and stops the engine so that the car would not accelerate any further and driver can steer it to roadside. In this system we use an Aurdino uno, Gps module, Gsm module with an alcohol sensor along with an dc motor to determine the concept. So here the alcohol sensor is used to monitor users breath and constantly sends signals to the microcontroller. The microcontroller on encountering high alcohol signal from the alcohol sensor stops the dc motor to demonstrate as engine locking. Once engine is locked then the microcontroller sends the signal to the gsm module now the gsm module sends signal to gps module to obtain latitude and longitude value obtained by the Gps module .these value is send to the car owner by the Gsm module sends the message of the car details and registration number . If alcohol is detected at the time of starting the engine the engine does not start at all. If alcohol is detected after engine initial, the system locks the engine at that time
