An Android Application for Driver Assistance and Event Alert System Using Ultrasonic Sensor and Heart Rate Sensor

With the increase in number of vehicles being used over the globe, we hereby look into some of the problems being faced by the drivers today. The problems that are in the lime light in this paper include Fuel quantity measurement, fuel theft detection, driver drowsiness, air pressure sensing in vehicle tyres etc. The Fuel quantity measurement and air pressure measurement is done using HCSR04 ultrasonic sensors. Output from both the sensors is sent to Raspberry pi and is further stored into firebase. Further android application retrieves data from firebase, displays the output on screen and generates the alert message in case of undesired events for eg: low fuel quantity, low air pressure in tyres. Drowsiness is detected using Heartbeat rate sensor which senses the heartbeat rate of the driver and sends the output to Arduino. Further through bluetooth technology, the data is shared with Android application and driver is notified incase of a positive drowsiness detection.
