Walk-in Freezer Monitoring Example
In this example above, a temperature sensor probe is connected to the FridgeAlert. The FridgeAlert 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!
