Library Utilisation Trends

The Montagu Street Library has 4 doors, each equipped with a Sensor that reports the status of the door, open or closed, the status of the battery in it, and the status of it's WiFi connection (on-line or offline) which goes down between actuations to maximise battery lifetime.
