Belize project

Hi @Andy, you mentioned in your post above that you hardcoded recording schedules into the firmware.

Could you please explain the procedure to hardcode recording times for every selected days in the firmware (ie which files to modify https://github.com/OpenAcousticDevices)?

I believe that the Audiomoth does not memorise the actual recording times but merely keeps track of the time to the next recording period (https://github.com/OpenAcousticDevices/AudioMoth-Firmware-Basic/blob/master/main.c). If that's right, I can't see how to hardcode times for every single days.

I'd like to hardcode sunrise/sunset times. I believe this option will be available in the next Audiomoth version (the one with the external mic option)?

Many thanks

EDIT: although not about hardcoding different recording times for every single days, this post deals with hardcoding a specific starting date for recording.

Hi all,

I'm also interested in recording poaching activity for a tapir conservation project. I would like to use customized programming using the algorithms already developed for gunshot detection. Can someone please point me out where the code is available and tell me a little bit more about this programming?

Thanks Andy! Next round (if and when round 6 happens)...could we order audio moths with the extra power connection PCB soldered on?

Hi Matthew, We used 6V lantern batteries for the Belize deployment, they are 26Ah which gave us about 400 days deployment period. For this deployment we changed the firmware quite significantly, changing the processor clock frequency and the way AudioMoth deals with audio samples to save energy. We also use the time setter app for all of our detection deployments, with recording schedules hardcoded into the firmware. Water proofing worked well, we used a coupling drain pipe (see image below). For this you need a separate PCB to be manufactured, this connects the PCB to the battery terminals. Andy

Hi Andy, I was wondering if you could share some of the details about how you modified your AudioMoths for the Belize deployments. Specifically - you modified your audio-moths to use d-cell batteries right? Did you have to use 3 batteries? How many Ah did that provide and for your consumption rate, how long a deployment period did you get? Was the power consumption consistent across our survey period...ie. did the consumption estimate from the app hold up for your long deployment period? How did you like your waterproofing solution after retrieving your devices? Sorry to pepper you with these questions...and please point me elsewhere if you have published these details elsewhere. Very excited to hear more. Matthew

Thanks Andy I look forward to reading it, Are you able to provide us with anything resembling a training database of the gun shots or even the raw audio files?

Hi Jenna,

Just incase you haven't seen yet, we published a recent Methods in Ecology and Evolution paper covering this project in a bit more detail. The Belize project is still ongoing, the Open Acoustic Devices team will be there next month to continue the work, so unfortunately the code won't be ready for release until later this year. If you have any more questions that the paper doesn't answer let me know.

Thanks Andy
