/* Testing MODBUS functionality
This code initializes a Modbus client, sets minimum and maximum water levels,
reads the current water level, and logs the results.
You can set the zero point and the 2m point for water level in lines 32 and 38.
This code initializes a Modbus client, sets the zero point and the 2m point for water level,
and reads the water level in both meters and millimeters.
It uses the Zephyr RTOS and its Modbus library to communicate with a Modbus server.
