Monitoring in real time across larger distances

2 comments

I am sorry if this has come up before but is it possible to link audiomoth to something else that can transmit what audiomoth hears in real time to a central computer? Where I would need to do this is remote but has 3G and I would be focussing solely on a single sound of interest - a rifle shot. This is early in my thinking...I know that this has been done to detect shotgun fire, but not as far as I can tell in realtime. In essence, I would like to use this as a realtime antipoaching measure. I am very open to collaboration here and have access to a field site that is perfect for developing this.

Hi, It's possible to use AudioMoth as the sensor for this. You would need to develop the sensor platform with the 3G modem as a standalone device, and then AudioMoth could communicate with this using the GPIO pins on the top surface of current PCB. The firmware would also need to be extended to implement this functionality. We've done this in Belize in a few trials using LoRa radio. Our development plan for AudioMoth 2 includes the idea of developing a 'dev board' version of AudioMoth that can easily be added onto another sensor platform to implement this type of functionality.

Thanks Alex. I'm not too tech-savvy but I think I get how this could work. I don't know much about LoRa but if could handle the data in real time then it sounds ideal. I also think it should be possible to use the timing of spearated devices in in detecting the shot to triangulate the position of the shooter reasonably accurately, which would be very useful. I guess my problem is that I know what the sysyem woulld need to do and I have a load of ideas about what would be great, but I don't have the knoweldge to know what is possible or how to get it to work! I do however have a perfect test site to determine whether it is possible to set up a simple, cheap and effective real-time monitoring network for firearms-based poaching, in this case rhino poaching in South Africa. So...if anyone is out there who could help please drop me an email :) ahart@glos.ac.uk

  • Hi, in all my recordings there's a "clicking" noise (26-28kHz). This is an issue that I had before with some recordings but now the noise is louder and it is present in all recordings. The batteries are Energizer AA (new) and the SD card is the SanDisk Extreme 32GB. Is there Anything I can do to make the "clicking" noise disappear?
  • Amazing work! https://www.openacousticdevices.info/mmoth Clearly it is early days, but obviously so many questions pop into mind ... - Off board Lithium ion battery, with a onboad connecter? (So you can choose any size LiOn? or LiPo? like - https://hobbyking.com/en_us/turnigy-2000mah-1s-1c-lipoly-w-2-pin-jst-ph-connector.html ?) - Any Battery life / runtime estimates vs AM1.1? - Cost? Double side so more expensive? - etc, etc, etc ... Anything else to share with us yet??
  • Hi, I'm attempting to modify the basic firmware, and I'm progressing quite well however there are a couple of sneaky scenarios which require a lower level debugging capability. Can you please advise how you debug the firmware, on the device? I've modified the firmware to call 'AudioMoth_setupSWOForPrint' at the end of AudioMoth_initialise() and added a couple of debug statements such as printf("Debugging enabled"); Throughout the code, being executed. These changes, along with my other alterations were then successfully flashed to the AudioMoth device. I've then connected my J-Link debug probe https://www.segger.com/products/debug-probes/j-link/ , which appears to support the EFM32WG980F256 chip. https://www.segger.com/downloads/supported-devices.php 1. PC -> USB -> AudioMoth USB plug (normal USB connection for an AudioMoth) 2. PC -> USB -> JLink Debug Probe -> SWD via Dupont Connectors -> AudioMoth Debug pads Here's a couple of photos to highlight what I'm doing. Sure, those connections are soldered a little rough but have been verified to be fine. As a simple dump, here's what I'm using. I'm expecting you're doing something similar when modifying the firmware.

J-Link> SWORead 0 bytes read (0 bytes in host buffer) J-Link> SWOView Receiving SWO data @ 4000 kHz. Data from stimulus port 0: ----------------------------------------------- Occasionally I'll get SWO output, but its all garbled and meaningless. On other hardware I would think this was a mismatch of the receiving clock (4000 kHz), but maybe I'm attacking this incorrectly. I appreciate this is getting down into the lower levels of core programming on the device but I suspect other users may wish to also understand these debugging aspects when modifying the firmware to suit their needs also. Without a device level debugging capability the only way to check out changes is to flash the device with extra LED flashes to highlight state changes, or log to the microSD via the AudioMoth_appendFile operation. Which SWO debug probe do you use to validate changes to the base firmware? What code changes do you make to enable debugging? Are there Simplicity Studio changes which you utilise to support debugging on the device? Are you debugging the code off the device instead, on a PC using a 32-bit ARM emulator or 32-bit x86 target toolchain? Are you implementing Unit Testing on your version of the firmware?
