<p>This system proposes a method to continuously monitor the tyre pressure using a simple rotary potentiometer. As tyre pressure is a contributing factor for speed, fuel economy, and traction in an automobile it is necessary for the driver to be intimated about any abnormality. The current system consists of a mechanical assembly with a rotary potentiometer. The potentiometer measures the angular displacement of the assembly and indicates the approximate tyre condition. The system can distinguish six different categories - Over pressure, Normal, 25% deflation, 50% deflation, 75% deflation & Full deflation. The system uses an 8-bit microcontroller to process the voltage from the potentiometers and indicates the result on an LCD display on the dashboard. This system can be a very simple and cheap replacement for both direct and indirect existing tyre pressure monitoring systems.</p> |
