RS232 Interface TPMS Solution External Cap Sensor for buses,trucks,GPS,GPS Tracker and other RX TX Wires Telematics Integration
The Development Kit is supplied with a RS232 circuit board for connection to PC, and power supply, Details of the communication protocols are provided to enable it to be integrated with existing instrumentation, telematics or security applications.
Application
The system requires engineering expertise to programme it into the host system, so it is appropriate for equipment manufacturer applications. It is not supported for individual retail customers.
Wireless direct tire pressure gauge and monitoring system for large off-road vehicles such as mining & construction,earthmover,container & cargo handling equipment and transit systems.
The innovative Tire Pressure Monitoring System ensure and help decrease your downtime and reduce your operating costs by giving you accurate tire pressure data.It also help you improve fuel efficiency,increase tire life and keep you moving.
