Bullet Points: 1Practical in Use: The tire preure auto alarm sensor is suitable for APP compatible with Android DVD navigation. And the voice alarm will be triggered when abnormal tire preure appears.2Easy to Use: Just plug and play, the sensor set features easy installation. And the sensor can display preure or temperature of 4 tires at the same time.3Powerful Function: The tire preure monitoring system (TPMS) can monitor tire preure and temperature status in real time. It will transmit real-time voice alerts and flash alarms to remind the driver of vehicle comfort and driving safety.4Varied Modes: The system features the adjustable high and low tire preure alarm value. The tire matching mode makes it easy to rematch new sensors. And the tire change mode makes it easy to change any two tires.5Wide Application: The system is widely applicable to vehicles with 4 tires, the maximum preure of the tire is 8.0 bar, such as commercial vehicles, off-road vehicles, minibuses and cars.Advantages:Manyaccidentsarecausedbytireleaksonthehighway.Asacarowner,drivingsafelyisatoppriority.Toreducesuchaccidents,atirepreuremonitoringsystem(TPMS)mustbeinstalled.WithTPMS,wecankeepthetireswithinthespecifiedpreureandtemperaturerangeatanytimetoreducetiredamageandensuresafedrive.PowerfulTPMS:1.Tirepreuremonitoringsystem(TPMS)canmonitortirepreureandtemperaturestatusinrealtime,anditwilltransmitreal-timevoicealertsandflashsirenstoreminddriversofvehiclecomfortanddrivingsafety.2.Displaytirepreureandtemperatureatthesametime.3.Leakagewarning,lowpreurewarning,highpreurewarning.4.Hightemperaturewarning,lowbatterywarning,nosignalwarning.Wideapplication:Thissystemiswidelyapplicabletovehicleswith4tires,themaximumtirepreureis8.0bar,suchascommercialvehicles,off-roadvehicles,minibusesandcars.4PCSsensors:Weoffer4sensorsaresuitableforuseinrainyweather.Inaddition,theyhavehighsensitivityandgoodaccuracyinmeasuringpreureandtemperature.Specifications:Internalsensor:Workingpreure:0-51psi/0-3.5barPreureaccuracy:plusorminus1.5psiTransmiionfrequency:433.92MHzWorkingtemperature:minus20-85degreesCelsiusStoragetemperature:minus40-plus125degreesWorkingvoltage:2.0-3.6VWaterproofIP67Battery:built-inCR2050buttoncellBatteryservicelife:2-5yearsExternalsensor:Workingpreure:0-51psi/0-3.5barPreureaccuracy:+/-1.5psiWorkingfrequency:433.92MHzWorkingvoltage:2.0-3.6VWaterproofIP67Workingtemperature:minus40-85degreesCelsiusStoragetemperature:minus40-plus125degreesBattery:Built-inCR1632120mAhbuttoncellBatteryservicelife:1-2years(canreplacethebattery)PackingList:1*TPMSReceiver4*ExternalSensor1*Wrench4*Anti-theftNut1*RubberPad1*Manual 1*USBCardReader
