XW-110™ WiFi Temperature Sensor Users Manual
Web Server
Module Description
This text will appear in email messages when email alerts are enabled as well as on the Control Page.
This field may be up to 35 characters long.
Temperature Update Interval
The XW-110 normally operates in a low power sleep mode and is programmed to periodically awaken
and measure the temperature. This setting selects how often this occurs. Depending on how emails are
configured an email may or may not be sent. When operating from a DC wall power supply this setting
can be set to most any value. Realize that every measurement requires energy from the battery. To
obtain the best battery life set the update for as long as possible for your application. For example, when
monitoring the temperature of a freezer use 15 minutes or so, for outdoor temperature which changes
slowly use a longer interval such as 30 minutes or more.
While the control page is open, this setting is temporarily ignored and every three seconds the browser
requests the state.xml along with a command to update the temperature and battery information. The
same is not true when just the state.xml is requested.
To save power in
Slave
mode the XW-110 normally disconnects from the access point. If the sleep
interval is less than 35-seconds the XW-110 remains connected since the energy required to re-connect
is greater than the energy saved by disconnecting.
Units
This allows the user to select between the temperature units of
Fahrenheit
and
Celsius
. All settings
entered and displayed on subsequent pages will be in the units selected.
Logging (XW-110-
Plus
only)
When this option is set to
Yes
, XW-110-
Plus
will record temperature data as configured on this page
(see
Section 5.2: Log File.)
The default setting for this option is
No.
Daily Email Log Send Time (XW-110-
Plus
only)
If logging is enabled, this setting determines the time each day when the data file is emailed.
Log Email Address (XW-110-
Plus
only)
If logging is enabled, this setting determines what Email addresses the daily data log is sent to. For
Email notification to work, the XW-110-
Plus
must have a properly configured network connection and a
SMTP server must be defined.
SENSOR 1-3
Up to three sensors can be connected to the XW-110-
Plus.
Separate setup fields for each sensor are
provided.
Sensor Description
The text in this field appears to the left of the corresponding temperature reading on the Control Page of
the XW
-110-Plus
and as the header of the XW-110. This text also appears in the email status message
when email is enabled. This field can be up to 14 characters in length. The default text in this field is
“Sensor #” for the XW
-110-Plus
and XW-110 for the XW-110
.
Sensor Address (XW-110-
Plus
only)
Each sensor connected to the XW-110-
Plus
should be associated (or assigned) to a sensor number.
This identifies the name, location, and function of the sensor. Every temperature sensor comes from the
factory with a unique, non-changeable address. When the sensors tab is selected (or the Refresh List
button is pressed), the XW-110 scans the bus for sensors. The addresses of the sensors that are found
on the bus are listed in the drop-down list. For each sensor number (Sensor 1... Sensor 3), select the
address of the appropriate sensor from the drop-down list.
