XW-110™ WiFi Temperature Sensor Users Manual
Installation and Setup
Freezer Temperature Example
Your want to monitor the temperature of a walk-in freezer and receive an email if the temperature is too
high. The freezer is within range of a WiFi access point. The HTTP web server is disabled to provide
long battery life.
Mount the XW-110 on a wall next to the freezer. Use an X-DTS-S3C temperature probe to monitor the
temperature inside the freezer. The XW-110 will not work inside the freezer because the WiFi radio
signal will not propagate thru the metal walls and the low temperature would severely diminish the
battery capacity. In this application, the XW-110 is workable with batteries because transmissions are
infrequent and the HTTP web server is disabled
For this application, configure the XW-110 as a stand-alone device with the internal HTTP web server
disabled. Configure the XW-110 to connect to your WiFi network as explained the previous examples.
Navigate to the sensor tab. Enter the period with which the XW-110 should monitor the temperature as
well as the temperature threshold for the alarm. To prolong the battery life set the update interval to 30
minutes or more. On the
Email Option
setting, select
Send email on High Alarm.
Click the submit button
at the bottom of the page.
Navigate to the email tab and enter the SMTP server settings as well as the username and password (if
required). You may need to contact your email provider for the exact settings to use. To provide
assurance the XW-110 is working, enable the
Weekly Status Email
option.
Once all the appropriate settings have been applied, click on the
Reboot
button, the XW-110 will then
reboot and begin low power operation. The XW-110 will no longer broadcast an SSID and the web page
will no longer be accessible. The XW-110 will periodically awaken, measure the temperature and check
for an alarm condition. If an alarm occurs it will connect to your WiFi access point and send an email.
Once each week the XW-110 will send an email with temperature and battery information.
