Parameter Monitoring and Functionality Control in Automobiles Using Raspberry pi

Abstract

In the current scenario where the world is moving towards modernization and automation, personal cars have become an integral part of people’s lives. This project focuses on improving a car from ordinary to smart by constantly monitoring parameters such as pressure of the car tyre and fuel level. The prototype also communicates to the owner of the car through SMS alerts and audio output to intimate reduced fuel levels, nearby gas stations and low car tyre pressure. This project is also incorporated with features like rain sensing wipers and theft alert at reduced costs. In addition to these, in situations where the owner loses his car keys or the keys are accidentally locked inside the car, the owner can unlock the car using his smart phone through a Bluetooth module and the output is shown using a gear motor. Raspberry Pi controller coordinates with different sensors like rain drop sensor, water level sensor, pressure sensor and vibration sensor to facilitate the features included in this project. To enhance the security of the car, a vibration sensor is included in the prototype and abnormal vibrations from the car door will be recorded as a robbery or a force open and alert is sent to the owner through a GSM module as SMS alert.
