7.4. Energy requirements of your system
In the Annex you will find some notes on current requirement. The current
consumption adds up from the continuous requirements for the logger,
interfaces and permanently supplied sensors on the one hand, and periodical
requirements for the actual measurements. The following graph shows the
current consumption [µA] in dependence to measurement rate. The
consumption rises considerably when the scan interval is less than 5 seconds.
The additional consumption that the interface needs during data read-out is not
considered. You can neglect this consumption if you don’t use the interface
more than 1 hour per month in long-term operation.

If you have a current consumption of 1 mA, the capacity of the internal batteries
is approx. 400...500 days. The life of the batteries decreases by up to 50% in
temperatures that are continuously below - 20°C.
