Screen display

I didn't get out for a walk today, with storm Barra roaring, so hear is one of a few photos that I took of this screen on one of our new freezers, in preparation for validating it. It's very clever - it records the temperature every minute, and uploads the data to the cloud via a Wifi connection. With an app on my phone, I can check the temperature, view the same graph as in the photo, and receive alarm notifications if the temperature goes outside the set limits.
