We have deployed four Audiomoths on Bird Island, South Georgia. The Audiomoths were programmed to record for 10 sec each five minutes but none of them are working correctly. Most of them record a single 10 sec clip before gradually dropping in size over the rest of the deployment 7-8 second (450-500kb), then dropping to 3-4 second (180-250kb) after a couple of days.
On attempting to transfer what files there are onto the hard drive there is an error code pops up (error code 0x80070052) ticking the ‘do this for all current items’ and skip files results in no files being transferred to the hard drive. This occurs with all the Audiomoths. Yet, the recordings do play straight off the micro SD inserted into the computer.
Any advice would be much appreciated!
Hi Rachel, Thanks for the message.
The first problem, looks like a low battery issue. Could you check the comments on the WAV files? You can see what voltage the batteries are at in the comments. These can be accessed using Audacity, Edit->Metadata...
What type of batteries are you using?
For the hard drive issue, this appears to be related to formatting. How are the SD cards formatted, and how is the external hard drive formatted?
