Feature 1External sensor, tire pressure, tire temperature of four wheel can display at the same time. 22color ambient light design, the blue light is on when the tire pressure is normal, and the red light is on when the tire pressure is abnormal. 3The original car battery voltage detection can effectively prevent the original car battery from igniting and starting the vehicle when the voltage is low. 4A variety of power supply methods, USB 5V power supply, direct USB power supply, can also be connected to other USB ports on the car 12V battery power supply. 5Digital clock display, effectively reducing the driver to look down at the watch or mobile phone. 6Monitoring temperature inside the car, the temperature inside the car is clear at a glance, easy to install, no need to remove the tires.Item Type: Car Tire Pressure Monitor SystemMaterial: ABS + MetalDescription: Many traffic accidents are caused by flat tires on highways. As a car owner, safe driving is the number one priority. In order to reduce the occurrence of such accidents, it is necessary to install a tire pressure monitoring system (TPMS). Through TPMS, we can make the tires work at any time within the specified pressure and temperature range to reduce tire damage and ensure safe driving.Fitment:The system is widely applicable to vehicles with 4 tires, the maximum pressure of the tires is 8.0 bar, such as commercial vehicles, jeeps, off-road vehicles, vans, cars, etc. with for Android displaysReceiverTransmission Frequency: 433.92MHzPower Supply: USB 5V / ACC 12V / OBD 12VOperating Voltage: DC 5V- 12V InputPressure Unit: Bar / PsiTemperature Unit: / Operating Temperature: -20-85 Storage Temperature: -40-125SensorTransmission Frequency: 433.92MHzPressure Range: 0-8 Bar / 0-116 PsiLow Pressure Alarm Value: 1.8 BarHigh Pressure Alarm Value: 3.0 BarAccuracy of Measurement: 0.1 Bar / 1.5 PsiOperating Voltage: DC+2.0-3.6VOperating Temperature: -20-85 Storage Temperature: -40-125Waterproof: IP67Battery: Built-in CR1632 Button Battery(Support Removable and Replaceable by yourself)Battery Life: 1.5-2 Years .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; }Package List1 x Host4 x Sensor2x PowerCable1 x OBD Power Supply4 x Nut1 x Wrench1 x Tape1 x Manual
