1.1 Project Introduction
This project is to design a device used to monitor the tire pressure and verify an inflated tire. This system continuously monitors the pressure sensors located in the tire.
The information collect by the sensors will transmit to on-board processor that interprets the sensor signals and warns the driver when the pressure is below the
minimum acceptable level by illuminating a warning lamp or show the value of tire pressure.
This device consists of two basic components which is tire Sensors which screw onto the valve stems of the tires, and a Monitor. The Sensors transmit a coded RF signal
and can alert if pressure drops. The Monitor displays each tire‘s pressure and can send an audible alert if tire pressures drop. During an alert, the low tire location light flashes
on the Monitor, the current pressure reading for that tire flashes, and an audible alert
sounds.

Problem Statement
Now days, most of accidents on the road were caused by tires. This is because the driver cannot monitor the tire pressure while their driving. Under inflated tires
typically result in increased tire wear, decreased vehicle performance, and compromise the ability of the tires to maintain a safe interface with the road. There are some reasons
to always properly inflate:
Vehicle Safety - Proper tire inflation greatly reduces the potential of a tire
blowout.
Improved Fuel Economy - Under-inflated tires increase the rolling resistance of vehicles and, correspondingly, decrease their fuel economy.
Enhanced Vehicle Performance - through proper tire inflation, will allow
optimum performance of vehicle with greater stability.
Increased Tire Tread Life - When a tire is under-inflated, more pressure is
placed on the tire, causing the tread to wear more rapidly than it would if the tire
were inflated to the proper pressure.
