AudioMoth Temperature Measurement


The AudioMoth micro-controller contains a factory-calibrated temperature sensor. This sensor has not  been used in previous versions of the AudioMoth firmware. However, version 1.4.0 adds a temperature measurement at the start of each recording with the results written to the comments section of the WAV file header.

Using AudioMoth with Filtering and Amplitude Threshold Recording


The most recent versions of the AudioMoth firmware (version 1.4.0) and configuration app (version 1.3.0) introduce two new functionalities: the ability to apply low-pass, band-pass or high-pass filters on the device, and the ability to reduce recorded file size by applying an amplitude threshold.

An injection moulded case for AudioMoth


While lightweight ziplock bags can be used to deploy AudioMoth for short periods of time in mild conditions there is a clear need for a more robust solution for long-term deployments. To address this need we have developed a waterproof injection moulded case specifically designed for AudioMoth.
