Changing Default Thresholds
The default thresholds are the initial threshold values that automatically
apply to numeric environmental sensors. These values are configured on
a sensor type basis, which include:

Temperature sensors

Humidity sensors (both relative and absolute humidity)

Air pressure sensors

Air flow sensors

Vibration sensors
Note that changing the default thresholds re-determine the initial
thresholds applying to the environmental sensors that are added or
detected later on.
In addition, changing the default thresholds also change the thresholds
of those environmental sensors where the default thresholds have been
selected as their threshold option. See
Configuring Environmental
Sensors or Actuators
(on page 246).
To change the default threshold settings:
1. Click Peripheral Devices in the EMX Explorer pane, and the
Peripheral Devices page opens in the right pane.
2. Click Default Thresholds Setup on the Peripheral Devices page. A
dialog appears, showing a list of all numeric environmental sensor
types.
3. Select the desired sensor type.
4. Click Edit or double-click that sensor type to adjust its threshold
settings, deassertion hysteresis or assertion timeout.
 To enable any threshold, select the corresponding checkbox. To
disable a threshold, deselect the checkbox.
 After any threshold is enabled, type an appropriate numeric value
in the accompanying text box.
 To set the deassertion hysteresis, type a numeric value in the
Deassertion Hysteresis field. See
"To De-assert" and
Deassertion Hysteresis
(on page 534).
 To set the assertion timeout, type a numeric value in the
Assertion Timeout (samples) field. See
"To Assert" and
Assertion Timeout
(on page 532).
5. Repeat the above step to modify the threshold settings of other
numeric sensor types.
