Abstract
In this paper A mobile application has been developed that can fetch various information about a car through various sensors interfaced with a microcontroller NodeMCU and the collected data uploaded to the cloud through raspberry pi server. NodeMCU sends signals to Raspberry pi to store the data in the cloud so that the mobile application developed may receive all these sensory signals and alert the passengers and driver. The proposed model also includes a feature to detect an accident and send the location of the accident to the user assigned person and local police station as a mobile message. In addition, the mobile application shall alert the driver to keep away from high speed vehicles coming from the rear side, present location of the car through google API, identify the road condition through pi camera interfacing and advise the upper speed limit, spray liquid nitrogen to reduce the temperature of tyres in the safe range of temperature, detect the driver status of drowsiness or alcoholic, detect the air quality about the harmful gas levels inside the car.
