AudioMoth is a low-cost, full-spectrum acoustic logger, based on the Silicon Labs Gecko processor range. Just like its namesake, AudioMoth can listen for sound from audible frequencies, well into ultrasonic frequencies. It is capable of recording uncompressed audio to micro SD card at up to 192,000 samples per second.

AudioMoth is an output from a research project at the University of Southampton and the University of Oxford to develop low-cost acoustic sensors for environmental and biodiversity monitoring. The hardware design, and all associated software, is open-source and freely available. Note that AudioMoth is a prototype research tool, and is not a commercial product. As such, it comes with no warranty or guarantee that it is fit for purpose.

This Group Buy was created by Alasdair Davies of the Arribada Initiative in response to requests from a large number of individuals all wishing to individually acquire an AudioMoth device. The individual price of devices from CircuitHub varies with their current component stock levels and the number of devices ordered. We have chosen a fixed price to cover this variation in cost and to support users. This cost does not include taxes and duties. This margin will be used to purchase additional AudioMoth devices to be held in a common spares pool and to provide trial devices to interested parties. The Arribada Initiative actively supports both the conservation community and the developers of conservation technology, and is exploring how open tools can help the developers of conservation technologies to distribute, support and maintain the devices they design into the future.
