Vehicle Fuel Monitoring Device with BLE 5.0

Vehicle fuel monitoring device UM770 is an advanced GPS tracker with advanced features that no other device include. With BLE 5.0 module, it can connect with wireless bluetooth sensors, including BLE door sensor, BLE temperature monitoring sensor, BLE driver identification button, BLE tire pressure monitoring and BLE wireless relay. Both BLE temperature monitoring sensor and wireless relay can work also without connecting with GPS tracker UM770.

With Charged Advanced and User friendly GPS web tracking software, the vehicle fuel monitoring device UM770 can support 2 tanks fuel monitoring at same time, by connecting with ultrasonic fuel sensor with analog voltage input, and the other with RS232 input.
