TYRE PRESSURE MONITORING SYSTEM (CONTROLLER AND DISPLAY)

Maintaining the correct tyre pressure for a vehicle is the variable on how much load
its tyres can safely drive. The correct tyre pressure can carry the weight without a
problem. Too little tyre pressure will eventually cause tyre failure that can lead to
many unpleasant accidents. This project requires students to study the existing system
of TPMS and to come up with depth research on how to design the system from
scratch and prepare the model of this system. This project is the initial background
work for the development of the miniature pressure sensor and controller unit for
TPMS. This main purpose of these systems is to warn the driver if their tyres are
loosing air pressure, leaving the tyres under inflated and dangerous. The systems
attach a pressure sensor together with transmitter to the vehicle's wheel inside the
tyre's air chamber. This project is performed by two students, the author and Mr
Khairul Asyraff. Mr Khairul Asyraff did the sensor and transmitter part while the
author did the microcontroller and the display part and finally both parts are being
merged and integrated. The final objective of the project is to design circuit consist of
pressure sensor, microcontroller (PIC), transmitter and receiver. The pressure sensor
used is a microelectronic device. This system will read a pressure inside a tyre and
transmit it to the receiver which can produce the output (display). This report
represents approaches to the scope of developing microcontroller and LCD display to
warn the driver that the tyre pressure is not sufficient. Input from pressure sensor is
required before a transmitter transmits data to receiver and the signal will be transmit
to microcontroller to convert the signal from analogue to digital before the value
being display. Mostly the related information is collected from reference books and
from the internet. As for conclusion, tyre pressure monitoring system is an interesting
area and important to make sure the safety of the driver and everyone inside the car.
