RS232 Module External Sensors Car TPMS UART
RS232 Car Tire Pressure Sensors TPMS with DVD External Sensors,RS232 Platform
Car application Drive recorder TPMS internal external sensors optional,
better quality competitive price directly from a professional manufacturer
Main Features;
1)with UART Communication technology,then DVD Monitor will show the tire pressure,temperature and alarming.
2)External Sensor or Internal Sensor Optional
3)4 tyre pressure and temperature can be shown on the car dvd player at the same time.
4)The data will be updated every 4 minutes normally,otherwise the monitor will alarm.
5) Using the special value chip,high efficiently prevent tyre explosion;
save fuel,foresee air leakage,reduce tire wearout and balance tire pressure.
6)RF Wireless technology support alarm automatically in case of abnormal on tyre pressure and temperature.
7)With UART Communication,easily connect to other system.
