RS232 TTL uart can bus tpms Internal 6 tires bus truck tpms wireless tire pressure monitoring system for truck bus trailer
The TPMS include 6 to 22pcs internal sensors, repeater and receiver. It is used to monitor the pressure and temperature data of the tires. After collecting the pressure and temperature data, the sensors send the data to the repeater and receiver by wireless, then the repeater send the data to the receiver. The receiver send the data to RS232 port, The instrument or other display device collect all tire data and display from can network. When the pressure or temperature over or under warning valve value, the instrument will warn automatically to remind the users pay attention to the tires’ situation. You can set tire number from 2 to 22, and you can select 6 tires or more, we will sensor 6 sensor if you not tell us how many pcs sensor would you like.


1.Support rs232 port
2.Support 1 to 22 tires
3.With the functions of ID learning/ID query/pressure and temperature measurement
4. send the tires data to instrument or other display device by RS232
2. All imports car-standard material, long life, high stability and strong anti-interference ability
3. Air pressure and temperature can be measured and monitored simultaneously, and have self-test and tire leakage monitoring function
4. Bandage sensor is only apply to all vacuum tire, external sensor is apply to all tire
5. Adopt IP67 protection grade, but the external sensor is IP69
Repeater(Model:RP04)
1. Transfer data, intelligent pull
2. Support trailer exchange function
3. When far distance and weak signal, can increase the signal strength to make sure the transferred signal reception reliability
4. Full thread fixing type, adopt IPX6 anti-water testing standard
5. Interior integration RF emit and receive function, high sensitive data receiving
6. Trailer sensors and receiver data transmission
7. Sole corresponding ID code, prevent data collision
