My evening has been spent programming AudioMoths for passive monitoring of birds in the Port Hills of Ōtautahi-Christchurch, NZ. When I swap over the units tomorrow it will mark 12 months of recording across 14 sites, from Ahuriri Bush in the west to Jollies Bush […] [Original post on mastodon.nz]

Our prototype NanoMoths are going out for field trials this week. Weighs just 6g including a 150 mAh Li-Ion battery and not much bigger than a micro SD card. Supports all the features of standard AudioMoth up to 192 kHz sampling rate.

#AudioMoth early ambitions of remote low-cost alerts has come closer to reality within a NatGeo funded project led by @jlahoz.bsky.social, integrating low-cost @arribada-i.bsky.social SMD Modules and Kinéis nanosatellites for real-time alerts from any location. #Tech4Wildlife @wildlabs.bsky.social

The left image shows an Open Acoustic Devices team member testing the first version of AudioMoth 1.0.0 with Lora radio integration in a Belize tropical forest. The AudioMoth is housed in an early prototype enclosure consisting of layers of clear acrylic laser cut sheets. Initial findings in 2018 indicated a wireless range of less than 50 metres.

The right image depicts the same team member testing the integration of satellite communication on AudioMoth Dev for real-time alerts and status updates on a remote location on the Isle of Wight, UK. The AudioMoth Dev is housed inside an AudioMoth Dev Case with an AudioMoth external microphone installed on the bottom left of the case with deac-cat windshield.
