Intelligent wireless tire pressure monitoring system, cigarette butt power supply with built-in display lithium battery, power cord extension in a variety of ways, 22 anti-collision replaceable battery external sensor, with special screw anti-disassembly design. Keep the tire balance to prevent sudden traffic accidents, reduce tire wear, save fuel, and prolong tire service life. The receiver screen shows the tire pressure and temperature of a certain tire, which can be switched by pressing the select button. The sensor is equipped with an external antenna to strengthen the reception of signals and effectively extend the receiving distance. When the tire pressure and temperature exceed the standard set value, buzzer alarm and flash screen. PSI, BAR two pressure unit options, ? Two temperature unit options. Each sensor has an independent ID code, which has been paired and installed directly before leaving the factory. Infineon chip solution for TPMS, imported battery, long-lasting power, more accurate monitoring data, real-time monitoring of tires to ensure driving safety. When the tire is normal, the sensor updates the data every 5 minutes. When the tire pressure and temperature are abnormal, a buzzer warning and a flashing screen are quickly issued.
