Abstract

The present disclosure discloses a system and method for monitoring tire pressure. The system includes a sensor, configured to sense a tire pressure over known time intervals, and generate corresponding pressure signals. Further, a controller, connected to the sensor receives the pressure signals over the known time intervals, subsequently converting the pressure signals into a compatible format, further processing and storing the processed signals in a memory. The controller is configured to include a calculating module, which is in turn configured to calculate a rate of change of the tire pressure and display the rate of change in tire pressure through a feedback interface connected to the controller.
