A customer required a remote river level monitoring system to measure water levels from 0 to 15 meters and transmit the data to a control station located 11 km away.The monitoring site is located in a remote river area where no cellular signal is available, while the control center in the city has a stable network connection. The customer also requested that the system support multiple communication options, such as GSM, WiFi, or LAN port, and asked whether a camera could be integrated for video monitoring.

In addition, the system must operate reliably in outdoor environments and provide stable water level data for river monitoring.
