Design and construction of a tire pressure monitoring system.

Abstract

Tire pressure monitoring systems are modules introduced in vehicles to monitor and analyse the tire pressure condition at any time. In this report two approaches were analysed that is direct and indirect tire pressure monitoring systems. Direct tire pressure monitoring systems refers to the use of a pressure sensor directly mounted on the wheels or tires of a vehicle. The pressure inside the tire is measured using a pressure transducer with the pressure information being subsequently sent to the vehicle to warn the driver of under or over inflation of a tire. Indirect Tire Pressure Monitoring Systems are the systems that do not have air pressure sensors inside the tires. Rather, they detect a low tire by comparing relative wheel speeds via the Anti-lock Brake System wheel speed sensors. When a tire loses air, its diameter decreases slightly. This project is majored on direct tire pressure monitoring system as it shows more accuracy as compared to the direct tire pressure monitoring system. The system was simulated using Proteus software that employs code using Arduino IDE and results were acquired and system tested before construction
