Power Modes
The Cirrus Loop Logger can operate in one of two power configurations.
Mains powered - in this mode the logger can be continuously connected to the server allowing for the streaming
of live data.
Battery powered - The Cirrus Loop logger uses standard 'D' Cell alkaline batteries that will last several years
depending on the operation. In this mode, the logger will 'wakeup' (adjustable - normally 6 hourly) and upload its
recorded data to a remote database.
External 12V (8-15V) 2A supply - in this mode the logger can be continuously connected to the server allowing for
the streaming of live data. Batteries can be fitted and the logger will automatically switch to battery mode should
the power fail.
