If the user has calibrated the sensor, the Calibrate Active field is set False (0)
and the sensor is operating inside the Min and Max Thresholds, the bits look
like 00000000 ? this is represented as 0.
If the sensor is using factory calibrations and it is outside the threshold, the bit
values are 00010010 and it is represented as 18 (16 + 2 because both the bit
in the 16 value is set and the bit in the 2 value is set).
Settings View
To edit the operational settings for a sensor, choose the Sensor option in
the main navigation menu and then select the Settings Tab to access the
configuration page. See Figure 8.
A. Sensor Name is the unique name you give the
sensor to easily identify it in a list along with any
notifications.
B. The Heartbeat Interval is how often the sensor
communicates with the server if no activity is
recorded.
C. Aware State Heartbeat is how often the sensor
communicates with the server while in an Aware
State.
D. Assessments per Heartbeat is how many times
between heartbeats a sensor will check its
measurements against its thresholds to determine
whether it will enter an Aware State.
E. Below is the minimum reading the sensor should
record before entering an Aware State.
F. Above is the maximum reading the sensor should
record before entering an Aware State.
G. The Aware State Buffer prevents the sensor
from bouncing between Standard Operation and
Aware State when the assessments are very close
to a threshold. For example, if a Maximum Threshold
is set to 90° and the buffer is 1°, then once the
sensor takes an assessment of 90.1° it will remain in
an Aware State until dropping to 89.0°. Similarly at
the Minimum Threshold the temperature will have to
rise a degree above the threshold to return to
Standard Operation.
H. In small sensor networks, the sensors can be set
to synchronize their communications. The default
setting ?Off?allows the sensors to randomize their
communications, maximizing communication
robustness. Setting this will synchronize the
communication of the sensors.
