This document describes a solar-powered tire pressure monitoring system (TPMS) that can wirelessly monitor and display the tire pressure and temperature of four wheels in real-time on a single screen. The system uses external sensors that are easy to install without tire balancing and can operate for up to two months on a single charge from its solar panel. It provides alerts for abnormal pressure or temperature readings and is designed to work for cars with tire pressures between 20 to 50 PSI.
