    HydroMoth is a variant of the standard AudioMoth specifically designed to be deployed in the underwater case.

    HydroMoth is the latest product from the AudioMoth range and offers everything needed to start recording underwater sound for extended periods of time at depths of 30-60m. HydroMoth hardware is directly compatible with all AudioMoth firmware, meaning you can use the device in any number of underwater applications, from scheduled recording in coral reefs, to triggering recordings by amplitude or frequency in freshwater ponds. HydroMoth has improved LED visibility and more accurate time keeping for long deployments. It also has an in-built magnetic reed switch, which enables recordings to be started and stopped in wet conditions without opening the case. HydroMoth is sold with the AudioMoth Underwater Case as standard, with the option to add a waterproof magnetic key chain fob to make use of the magnetic reed switch.

    Applications in freshwater sound surveys, coral reef soundscape monitoring, cetacean underwater acoustic studies, or boat noise monitoring.

    • Re-positioned LEDs for improved visibility in the underwater case.
