A tire pressure monitoring and speed control system.

Abstract

The tire pressure monitoring and speed control system is a microcontroller based system that notifies the driver of the amount of tire pressure in the vehicle tires. This system is able to control speed of the vehicle depending on the amount of pressure in the tires. If the tire pressure drops 15% below the recommended then system notifies the driver of this loss with a beeping and then mitigates the car speed to less than 60km/hr. There cases where some drivers inflate car tires to that which is above the threshold tire pressure for a given vehicle, so this system is also able to notify the driver with a beeping sound then controls speed to less than 60km/hr. The tire pressure monitoring system is placed inside the tire with a cell as the power source then the system is protected with a rubber casing to prevent damage. The speed control system is connected to the engine so as to control speed for cases of low and high pressures. The two modules communicate wirelessly using radio frequency where the transmitter circuit is in the tire and the receiver circuit inside the car system. The user interface is the liquid crystal display where the tire pressure is displayed in real time
