Set up your AudioMoth

A note on AudioMoths

AudioMoths are an affordable and effective survey tool. However due to their low cost they are also fragile and need to be handled with care.

In particular, the white slider switch can be broken, the glue which holds the circuit board to the battery holder can come unstuck, and the weatherproof mesh on the case can come loose. To help keep your AudioMoth in working order:

  • Be gentle when inserting and removing the AudioMoth from the weatherproof case. The foam insert is a snug fit around the switch of older versions of the AudioMoth. Newer versions have a new indented switch.
  • Slide the switch gently.
  • When removing or inserting batteries, hold the battery holder, not the circuit board.
  • When inserting or removing the SD card hold the circuit board, not the the battery holder.
  • Transport the Audiomoth and weatherproof case inside the padded envelope you received it in.

To set up your AudioMoth

To set up your AudioMoth use the 'chime' which plays when you press the button below. The recording settings for the survey are embedded in the chime. When the AudioMoth hears the chime it applies the correct settings.

  1. Set the switch to USB/OFF.
  2. Insert a blank microSD card. The SD card should be inserted print facing down.
  3. Insert three AA batteries. Fresh lithium AA batteries will last four nights before they need to be replaced. Fresh alkaline AA batteries will last for three nights. Please do not use rechargeable batteries as they will cause the AudioMoth to fail.
  4. Open this webpage on a device that can play a sound, such as a computer with speakers, a laptop, tablet or smartphone (currently the chime only works on Android smartphones, not iPhones). Check that your device is not set to silent.
  5. Move the switch on the AudioMoth to DEFAULT. The green LED will flash every two seconds while it waits for the chime.
  6. Click the button below to play the chime.
  7. If the configuration has been successful the green LED will stay on continuously. You may need to experiment with different distances and volume settings until the green LED stays on. You can push the 'play chime' button as many times as you need.
  8. Once the AudioMoth has been successfully configured, move the switch to USB/OFF to switch the AudioMoth off.

Important note - If the batteries are removed or dislodged the AudioMoth will lose its setting, indicated by the red LED flashing (if the red LED is lit continuously this is not an error, it indicates the AudioMoth is recording). If this happens the AudioMoth will need to be reconfigured following the steps above.
