Development of a Frugal Onboard Tire Pressure Monitoring Control System

Abstract Tires, the bridge between vehicles and roads, play an unparalleled role in both performance and safety. In everyday use, the tire health is often neglected, with factors such as tread depth, inflation pressure, and tire damage overlooked by most users, leading to $$\sim$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mo>∼</mml:mo> </mml:math> 30% of cars in developed nations, operating with underinflated tires, a situation exacerbated in developing nations. Hence, innovations such as tire Pressure Monitoring Systems have become imperative. The objective of the current work is to develop an economical, direct, on-board tire pressure monitor for automotive tire health upkeep. This is achieved through the integration of a pressure sensor and transmitter with an Arduino, and wireless transmission of the data to the dashboard display. While the initial model, tested on a bicycle, effectively displayed tire pressure on the handlebar-mounted LCD screen with an accompanying LED indicating deviations from the standard pressure, the current design has lot of scope for improvement by the utilization of a wireless technologies for the pressure sensors for continuous monitoring of tire pressures in a range of vehicles from two-wheelers to heavy vehicles.
