•Tire Pressure Monitoring System(TPMS), which lets the driver get the real-time tire pressure data, temperature data and status, always keeping an eye on your car's performance •Support shows four wheels's tire pressure and temperature simultaneously,high/low tire pressure alarm, high temperature alarm and air leakage condition alarm •Real-time notification of the tire pressure condition of each tire, the driver can guarantee the pressure balance of the four tires according to the tire pressure value, so as to achieve smoother running •After fix the sensor on the four tires, the receiver can be sitting on any surface of the car. When the vehicle is started, the built-in displacement sensor of the host computer automatically starts the host without manual startup •When a tire tire pressure is too high or too low when the host issued an alarm sound and display the tire pressure value, and locate the tire tire pressure is not normal to quickly find the problem of tires •When a tire temperature is too high, the host alarm sounds and displays the real-time tire temperature value, and locates the tire with too high temperature so that the driver can make corresponding treatment •Combining with the solar energy display, there is no need to connect the power cord and it saves precious on-board power supply ports Specification: •Display screen:LCD •Operating temperature: -20℃ ~ 70℃ •Working voltage: 5V •Daytime operating current/Night operating current/Standby current:＜15mA/＜4mA/＜50uA •Transmission frequency:433.92MHZ+/-20KHZ •Transmission mode:FSK •Pressure unit: BAR/PSI •Charging ways:Solar energy/USB •Battery:1*303450 3.7V 500mAh •Monitor size: Approx.9.5*8.5cm/ Package included: •1 x Tire pressure tester •4 x Sensors •4 x Anti-lost Nuts •1 x Portable Tool •1 x Charging Cable •1 x User Manuall(English) •Other things not included
