+This plugin collects the value of the available sensors in an
+I<AquaeroE<nbsp>5> board. AquaeroE<nbsp>5 is a water-cooling controller board,
+manufactured by Aqua Computer GmbH L<http://www.aquacomputer.de/>, with a USB2
+connection for monitoring and configuration. The board can handle multiple
+temperature sensors, fans, water pumps and water level sensors and adjust the
+output settings such as fan voltage or power used by the water pump based on
+the available inputs using a configurable controller included in the board.
+This plugin collects all the available inputs as well as some of the output
