Solar charging, no need to connect the car cigarette lighter to charge, wireless connection through the sensor, easy to install. 2. LCD digital display, clear tire information, easy to observe, beautiful and compact, 3. The tire pressure unit Psi and Bar can be switched arbitrarily and can be used universally all over the world. 4. A more complete and fully sealed rain-proof and dust-proof design can cope with various complex environments. 5. Two tests can be performed simultaneously and displayed on the same screen, real-time monitoring of the pressure and temperature of 4 tires 6. The external sensor using Freescale chip, through the radio frequency technology, real-time data transmission, always accurately monitor the tire pressure, the signal receiving distance is long, the signal is stable. Applicable to almost 98% of cars on the market. 7. With low air pressure, high tire pressure, high temperature alarm, sensor battery low alarm 8. Intelligent switch, automatic sleep after parking for more than 10 minutes, and automatically turn on when vibration is detected, which is more convenient.
