With the increasing vehicles and their movement on the roads, accidents are also steadily increasing. It has become difficult for the authorities to prevent or reduce such fatal accidents on the road and all their efforts are in vain. So our idea is to design a module which can detect the vehicle position whenever driver drives the vehicle above permissible speed limit and transmit the data with live GPS location to the concerned authority’s mobile phone in the form of SMS.
RPM (speed) of wheel of vehicle is detected using inductive proximity sensor. We are using a DC fan with potentiometer to vary speed. The sensor is interfaced with Arduino uno development board which has Atmega328 microcontroller. The status is displayed on 16×2 LCD. Arduino board is interfaced with GSM to send alert SMS. GPS gets latitude and longitude data from the satellite which can be used for live location tracking. We are using LEDs to roughly indicate the speed of the vehicle for the vehicle driver convenience. Buzzer gives alert sound whenever RPM crosses specific threshold value. Regulated power supply is given for all the units. We can use a battery dc power source in a vehicle.
