Description
External tire pressure sensor is installed in the car hub and automatically monitors tire pressure, temperature, and battery level.The built-in sensor and the external sensor are installed in different positions, but because the external sensor is directly installed on the gas mouth, the accuracy of the tire pressure measurement will not be affected. In the measurement of tire temperature, the external sensor will have an error of 1-2 degrees compared with the built-in one.
The external tire pressure sensor uses a wireless transmitter to send pressure information from the outside of the tire to the central receiver module, and then displays the pressure data of each tire. When the tire pressure is too low or the air leaks, the system will automatically alarm.The transmitter system consists of the following parts: electronic part (including tire pressure module, crystal oscillator, antenna, RF module, low-frequency module, battery) and structural part (shell, strap).
