Solar Wireless Car Tire Pressure Monitoring System with 4 External Sensors

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\u0027s performance. Support shows four wheels\u0027 tire pressure and temperature simultaneously,highCelsiuslow tire pressure alarm,high temperature alarm and 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.
