WiFi Temperature Monitoring

  • XW-110P,XW-110P+PS5VW1.0-2.5MM

The XW-110™ is a drop-in temperature sensor with a built-in web server. It’s capable of monitoring up to three 1-Wire sensors. (One 1m sensor is included.)
1 Temperature Sensor

  • WiFi-Enabled (802.11 b/g/n)

The XW-110 is easy to use and can quickly be mounted to a wall or other workable surface. It can run on battery power and can be configured to send out a notification in the event of a power loss. As a self-contained device, no additional servers or software are required to provide live, real-time temperature status through a standard web browser.

XW-110 Features

  • Temperature Logging
  • Email Notifications
  • AC Power Failure Notification
  • Temperature probe Range: -67°F to 257°F (-55°C to +125°C)
  • Temperature Probe Accuracy: ±0.5°C (from -10°C to +85°C)

Wireless Temperature Sensor Applications

As a standalone device, the XW-110 excels in a wide variety of applications where it can be used as a drop-in solution where hard wiring isn’t practical or convenient. Some examples include:

  • Refrigeration/Freezer systems
  • Commercial properties
  • Water treatment plants
  • Chemical plants
  • Pharmacies
  • Laboratories
  • Greenhouses
  • Weather stations
  • Attics
  • Wine cellars
  • Server rooms
  • Cold storage rooms
  • Storage facilities
    … and many more!

Once connected to a network, you can access the temperature sensor’s setup and control pages on a web browser where you can adjust the settings, or view the current temperature on the XW-110’s control page.
