It continues to be difficult to source microcontrollers due to global supply chain issues, but Open Acoustic Devices have managed to source a small supply for an initial group purchase campaign of HydroMoth; a variant of AudioMoth intended for making underwater recordings.
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. HydroMoth will be ready to ship immediately after the campaign close date. Click here to find out more.
