Internet of Bats
summary
Describes a wildlife-monitoring system using infrared light barriers (initial 48-sensor array then redesigned with multiplexed shift-registers and a custom PCB), 250 kHz ultrasonic recorders and occasional camera sync to detect bats. Covers practical issues: off‑the‑shelf ultrasonic capsules (~€250), unreliable UMTS sticks, many sensor failures and some deployments never coming online, plus prototype SDR triangulation (on hold). Also notes implemented data logging, VPN and simple web logging and that open build instructions are published.
