4.
For Battery Low and Sensor Failure alarms:
a.
Under Device, select the Battery Low and/or Sensor
Failure checkboxes.
b.
Select how you want to be notified when these alarms
trip: by email or text. Enter the appropriate addresses
and then select “Send on Clear Also” if you want an
email or text when these alarms clear as well.
5.
Click Add Action if you want multiple actions to be taken
when the alarm trips (for example send an email and a
text).
6.
Click Save. Changes will take effect the next time the station
connects to HOBOlink.
Red alarm symbols will appear in HOBOlink when these alarms
trip (if enabled).
Sensor Alarms
To add a sensor alarm:
1.
In HOBOlink, click Devices and then RX Devices, and find the
station you want to configure. Click the arrow next to
and select Alarm Configuration.
2.
Click Add a Sensor Alarm.
3.
Set up the Sensor Condition for the alarm.
a.
Select the sensor.
b.
For rain gauge sensors:
This is based on accumulated
rainfall in inches or mm (depending on the units set in
HOBOlink) over a period of minutes or hours (up to 24).
Enter the number of minutes or hours you want the
rainfall to be accumulated over, and the amount of rain
in inches or mm you want to trigger the alarm.
c.
For all other sensors and channels:
Select whether the
alarm should trip above or below a value or outside a
range. Enter the sensor reading(s) for the alarm
threshold. Enter the number of logged data points you
want the station to record before the alarm trips.
Note:
If you are setting up a sensor alarm for a water flow
channel that is using a stage-discharge table, be sure the
alarm limits are within the range of the stage-discharge
values you are using.
d.
If you selected the alarm to trip above or below a
specific reading, then select when the alarm should
clear: above or below the same value or a different
value. Enter the value if necessary.
4.
Select the action to be taken when the alarm trips: send an
email or text. Enter the details and then select “Send on
Clear Also” if you want an email or text when the alarm
clears as well.
Important:
Standard data fees and text messaging rates
may apply when using text notifications. Onset does not
charge a fee or guarantee delivery of text alerts, which is
subject to your carrier’s service and location. See the
HOBOlink Help for additional details on alarm
notifications.
5.
Click Add Action if you want multiple actions to be taken
when the alarm trips (for example, send an email and a
text).
6.
Add any optional notes for this alarm.
7.
Click Save. Changes will take effect the next time the station
connects to HOBOlink.
8.
Repeat steps 2 through 7 for each additional sensor alarm
you want to add.
Note:
There is a limit of eight alarms
allowed for all water level sensor channels (this includes
barometric pressure, water pressure, differential pressure,
water temperature, water level, and water flow).
If an alarm trips on a smart sensor or water level sensor
channel, the station will automatically connect to HOBOlink to
report the tripped alarm. A red alarm symbol appears next to
that sensor in HOBOlink when it trips. An alarm symbol will also
appear on the LCD.
Note that for water level and flow alarms, HOBOlink calculates
the corresponding differential pressure value so that this can
trigger an alarm by the station the same as other sensors, and
trigger an immediate connection if there is an alarm condition.
Alarms for HOBOlink calculated channels (such as dew point)
are checked at the connection interval for the station. This is
because calculated channels are generated from data uploaded
at each connection interval.
Accumulated rain alarms are triggered by the station as soon as
the alarm conditions are met. The alarm will remain tripped for
one accumulation interval after the trip. For example, if you set
the alarm to trip for 2 inches of rainfall accumulated in 4 hours,
then it will be 4 hours before an alarm clear message is sent
after the alarm is triggered--unless enough rain has continued
to accumulate that causes the alarm to trip again.
Setting up Water Level and Water Flow
Channels in HOBOlink (RX2103 and
RX2104 Models)
RX2103 and RX2104 models support a water level sensor.
When installed, the station will automatically log four
measurement channels:
•
Barometric pressure
•
Water pressure
•
Differential pressure
•
Water temperature
In addition, you can set up two additional channels in
HOBOlink:
•
Water level
•
Water flow
These derived channels are only available once enabled in
HOBOlink. The data for these two channels are calculated at
each logging interval based on the measurements from the
pressure and temperature channels and the settings and values
you enter in HOBOlink.
