+/*******************************************************************************************************
+  Program Operation - The program reads a single DS18B20 temperature sensor and prints the result to the
+  serial monitor.
+
+  The program also has the option of using a logic pin to control the power to the lora and SD card
+  devices, which can save power in sleep mode. If the hardware is fitted to your board then these devices are
+  assumed to be powered on by setting the VCCPOWER pin low. If your board does not have this feature set
+  VCCPOWER to -1.
+
+  Serial monitor baud rate is set at 9600
