**Product Description:**
The TW501 is a high-performance Wireless Tire Pressure Monitoring System (TPMS) that connects via OBD and Bluetooth to your smartphone. This device allows you to monitor tire pressure and temperature in real-time through a dedicated mobile app. When the tire pressure or temperature is too high or too low, it alerts you using a human voice alarm in either Chinese or English.
With this system, you can easily configure your tire pressure settings directly from your phone, including matching tires or changing their positions. The external sensors are designed for easy installation and provide accurate readings across all four tires simultaneously.
This TPMS supports both Android and iOS systems and offers flexible units such as PSI and BAR. It also includes configurable alert settings for pressure and temperature, giving you full control over your vehicle's tire conditions.
