Feature 1Tyre pressure that is too high or too low will cause tire wear. TPMS helps reduce tire wear, prevent tire explosions, save fuel, and maintain good car maintenance. 2With the help of TPMS, we can keep the tire pressure and temperature within the specified range at any time to reduce tire damage and ensure driving safety. 3Solar charging + USB charging, no need to connect the car cigarette lighter to charge, high power transmission and high performance, wireless connection with the sensor, easy to install. 4The color LCD digital display can clearly display the tire information during the day and night, and monitor the pressure and temperature of the 4 tires in real time. 5Low air pressure/high temperature alarm; high temperature/leak/low battery alarm; smart shockproof cover when the car is driving, no need to open/close. 6Over 40% of traffic accidents on highways are caused by abnormal tire pressures. In order to reduce such accidents, a tire pressure monitoring system (TPMS) must be installed.Item Type: Tire Pressure Monitor .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Material: PC + Nylon Fiber + Copper Air NozzleHost Parameters:Built-In Lithium Battery: Capacity 500mAh Model 402040Display: Pressure, Temperature, Air Leakage AlarmFrequency: 433.92MHz20.00MHzWorking Temperature: -20-80Storage Temperature: -30-85Charging Method: USB+SolarCharging Voltage: DC 5VFactory Default High and Low Pressure Values: 3.0Bar-2.0BarWorking Current: 5MAFactory Default Temperature Value: 68Installation Location: Center ConsoleSensor Parameters:Button Battery: Capacity 60mAh Model CR1632 (Included)Waterproof and Dustproof Rating: IP67Frequency: 433.92MHz20.00MHzSensor Pressure Range: 0-3.5BARStorage Temperature: -30-86Accurate Pressure: +/-0.1BarAccurate Temperature: +/-3External Working Temperature: -20-80Built-In Working Temperature: -40 - +120Instructions for Use: Plug and PlayHow to Install:1.
