Graph Window
Temperature data and RF signal strength (RSSI) for all nodes can be plotted in a graph (see
).
The signal strength is displayed as a percentage. The last 60 transmissions are stored and displayed.
Only 24 hours worth of data can be displayed.

COM Port Selection
By default, the application selects and opens the first available MSP430 Application UART and refreshes
the drop down whenever a new COM port is available. This means it is rarely necessary to use the COM
port selection list unless multiple MSP430 Applications UARTs are available on the PC.
4.2.3.5
Configurations
Settings for the Sensor Monitor application can be changed in the configurations window. The default
temperature unit can be modified as well as the time required before a node is removed if a packet has
not been received in a while.
