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
