Connecting Audio Moth to Raspberry pi zero

Hello,

I want to connect Audio moth to a raspberry pi zero with Audio moth USB microphone firmware cause I need to control it and transfer files remotely. Raspberry should power it through USB port. I want to record the data with python and pyaudio. I need your help for some questions.

1 - I don't know if I should remove the internal batteries. If Audio moth has its internal battery and it is connected to Raspberry with usb port, it will be powered by the USB or the batteries ?

2 - Can I change the Audio moth configuration with the app installed on the Raspberry remotely (without needing to change any switch on the board) ?

3 - What is the maximum power consumtion of the board ?

4 - can I install Audio moth configuration usb app on the raspberry pi zero

Thank you

Hello Alex. A more basic question is how to wire up a RPi to collect and analyze the data it receives from an Aquarian hydrophone? Is there a Application note for using AM USB Microphone? Thanks, Mike

The full list of applications notes is here: https://www.openacousticdevices.info/application-notes This one describe the hardware and firmware and how to use Python and arecord on a Raspberry Pi to make recording. https://github.com/OpenAcousticDevices/Application-Notes/blob/master/Using_the_AudioMoth_USB_Microphone_Firmware_and_Hardware/Using_the_AudioMoth_USB_Microphone_Firmware_and_Hardware.pdf This one describes AudioMoth-Live which has a command line variant that works really well on Raspberry Pi to make fixed length recordings in the background. https://github.com/OpenAcousticDevices/Application-Notes/blob/master/Using_the_AudioMoth_Live_App_with_the_AudioMoth_USB_Microphone/Using_the_AudioMoth_Live_App_with_the_AudioMoth_USB_Microphone.pdf Depending on the application, I thnk the easiest route is to use AudioMoth-Live from the command line to make recordings into a folder, and then have an analysis script that reads, analyses and maybe also forwards them onwards.

Hi,

You can remove the batteries - the AudioMoth will be powered from the USB port.
No, with the current firmware you cannot reconfigure the AudioMoth USB Microphone when it has enumerated as a microphone - you need to switch back to USB/OFF mode.
The AudioMoth will use about 20mA when running as a USB microphone.
You cannot install the binaries directly, but you can install Node of the Raspberry Pi and build the same application from the GitHub repository.

If this use case takes off, we'll look at building some simple configuration tools for Raspberry Pi.

Hi Anahita, you aren't by any chance working on a system to automatically upload audiomoth data from the field are you?

HI Alec,

Well I would like to do it but it depends on the company I work for. As it needs time and develipement , I'm not sure if they want to investigate. Are you working on it ?
