Abstract
A system for displaying dynamic readings of a motor vehicle's tire pressure, temperature and tire ride efficiency comprises individual integrated units that are removably attached to each valve stem. Each unit comprises a pressure sensor and a temperature sensor coupled to a microcontroller which activates a transmitter/receiver set with a measured signal. The signal is received by a transmitter/receiver set in a passenger compartment mounted display which feeds a signal through a microcontroller to the display unit. In operation, theft prevention serial numbers of the remote sensors are entered in the display unit. Each individual sensor may then be queried sequentially with the appropriate serial number to provide a pressure and temperature reading for a particular tire as well as battery condition. The readings and warning signals are activated in the display unit.
