Duty Cycling
Duty cycling allows for a longer deployment time, saving battery during inactive periods (when
hydrophones are not recording). To make the most out of your smart recorder duty cycling choose a
period and active time that works best for your project. This is a trade between the length of the
deployment, the battery power and memory capability of your system. Use the excel sheet provided on
the USB with the Gordon Smart Recorder to help choose the settings that will provide the most useful
data from your deployment.
The Gordon Smart Recorder will turn the power to the hydrophones on and off. This allows for longer
deployments. The duty cycle is a period of sleeping (inactivity) and a wake period (activity) where the
hydrophone is recording.
Period: The total time of the cycle (active and inactive time).
Active: The time where the hydrophones are recording.
