4.4. Sensors Data and Battery Level Indication
WSN activity is observed in two ways:

Node State
Standby
Searching for network
Joined to network
Sleeping (end device only)
If you power ON the coordinator, it switches to an active state, even though no child node
is present. This is normal, it means that the coordinator is ready and child nodes can join
the network with coordinator’s PAN ID.
By default, coordinator uses predefined PAN ID valued as D170, which is recognized by
all routers.
NOTES:
If coordinator is absent or it has not been turned on, the routers are staying in the network
search mode. In this mode, routers are scanning the selected frequency channels in
search for a network with the selected PAN ID.
In rare cases, if radio channel is busy on the selected frequency the coordinator node is
staying in the network searching mode. If this happens, you should switch it to other
channel by changing the channel mask in WSN Monitor.
Each of the boards measures temperature, light and its own battery level. They send the
data values to coordinator and, further to the PC. The WSN Monitor displays the readings
from onboard sensor’s next to a node icon along with visualization (see Section 4.5).
Temperature sensor measures ambient temperature. The sensor data is depicted in the
WSN Monitor charts with resolution of 1 °C, but the actual sensor accuracy is better. Light
sensor measures ambient illumination in Lux. The battery voltage is indicated with typical
accuracy of about 0.1 V, which is enough for most applications and self-monitoring tasks.
NOTES:
In case the board is powered via USB port, the battery level might be shown improperly.
Typically, it is shown as 0.6 V due to power protection circuitry. However, if batteries had
been installed into the battery compartment, when the board is connected to the USB, the
battery level indication is correct.
In case the board is powered via USB port, the heating voltage regulator, which is located
next to the temperature sensor, can distort the sensor readings. Use battery-powered
boards for more accurate measurements.
