Wildlife Monitors


AudioMoth as a Wildlife Monitor

The AudioMoth is a standalone wildlife audio capturing device. This example shows a device setup for measuring the audio levels of wildlife as a metric to capture changes in the ecology of a chosen site.

The unit works by recording audio to an SD card for manual collection by site management staff. Data can then be downloaded to a computer for processing or storage of data.

As per Hardware Management this hardware will follow the following setup:

Step 1. Device Setup

Devices purchased against client request would need the following information recorded:

  • Device Information
    • Device Model Number: AudioMoth
    • Device Serial Number: <The devices EUI Number>
    • Device Firmware Version: <Taken from the devices CoC or Board certification>
  • Measurement Information
    • Metric 1: MEMS microphone recording with accuracy of (-38 ±3 dBV/Pa @ 94dB Sound Pressure Level @ 1kHz); user specified sampling rate.
  • Calibration Information
    • Standard Used: None provided by manufacturer.

Step 2. Calibration

Calibration of this device requires the use of post processing offsets once the data has arrived. No manufacturer guidance provided so a note of the offset per individual device will be required.

Step 3. Hardware Deployment

  1. The AudioMoth is configured before deployment.
  2. the AudioMoth’s position is chosen on a map and general notes on the following taken:
    • Note on habitat,
    • Note on general positioning.

Step 4. Data Security

Data is recorded onto an SD card. The devices are deployed in remote locations so as to not be noticable. The chance of maliscious effect are seen to be extremly low.
