Wireless freezer monitoring and logging with ControlByWeb's XW-110 Plus Wireless Temperature Sensor.

Temperature sensor probe connected to the XW-110 Plus to monitor and log freezer temperatures.

Walk-in Freezer Monitoring Example

In this example above, a temperature sensor probe is connected to the XW-110 Plus module. The XW-110 Plus then communicates with a local network. You can access its built-in web pages by connecting a computer to the same local network and you can remotely monitor the temperatures from those web pages.

Text/Email Temperature Alerts

Sends a text message or email alert if the high/low temperature threshold is reached.

Log Temperature Data

Periodically log temperature data which can be sent daily via email. Perfect for maintaining compliance with FDA requirements to maintain food temperatures in coolers and freezers. No more manually logging temperature data by hand!

Free Mobile App

You can also use our free, CBW-Mobile app to access the XW-110 Plus and any other devices on one central control panel.

No Cloud Services or Monthly Fees
