Figure 4.19 Sensor Parameters
Sensor Name: Name of this End Device.
Update (seconds): How often this sensor is sending its data to the Coordinator.
Offset: Since the sensing technology in an End Device is solid state electronics, there is
no need for calibration. If it is determined that the readings are slightly off, the user can
manually assign numerical values to adjust the readings for temperature (in degree C) ,
humidity (in percentage), and barometric pressure (in mbar). The offset value can either
be a positive or a negative number with one decimal point
Update: Saves changes
Reset Value: Ignores changes and puts to previous values back in the fields.
Cancel: Ignores all the changes and goes back to the “Sensor Setup” page.
Reset Sensor: Reset the End Device readings and status. If the End Device is not on
the network, the data will be cleared after about 3 minutes. Otherwise, the End Device
will reset itself and re-join the network.
Identify: INACTIVE: End device is in running mode and sending data to the Coordinator
periodically. ACTIVE: End device is in identify mode and it keeps its blue LED on solid
so that operator can identify the corresponding sensor easily.

Update rate is closely
related to the lifetime of
the battery.
Since the End Device is in low
power consumption (sleep mode)
when idle, a longer update rate will
cause less energy usage and
prolong the life of the battery.
On the other hand, a faster update
rate shortens the battery life and
results in a busy network, which will
increase the chance of signal
interference.
As a general rule of thumb,
minimum update rate should be
proportional to the number of
sensors in the network.
