The GSM-batcorder is based on the batcorder 3.1.. In addition it already contains the control unit of the wind turbine extension. Thus, the GSM-batcorder can not only directly send the daily status message per SMS, but can also be programmed using SMS commands. Just message and it will obey. Used first in 2017 it has established a new way of monitoring bats at wind turbines.
It also features an USB port to connect a computer. This again allows for a multitude of usage scenarios - most prominent the remote data access. Connect the GSM-batcorder to a computer and bring your data anywhere.
Utilizing an USB connector the GSM-batcorder can be connected to any computer. We have established a simple script-based backup system running on a Raspberry Pi. This automatically backups newly recorded bat sounds on an external memory connected to the Raspberry Pi using rsync. Practically that is a USB memory stick with capacities of 128 GB or more. If the Raspberry is connected to the internet a status message is sent daily as well informing about successful backup and the backup available space.
For remote access the Raspberry Pi must be connected to the internet (fixed IP at the router) and the turbine internet router needs to forward a port to the Raspberry for SSH. That has to be established by the turbine owner. If setup correctly you can connect via SFTP and download recordings to your office.
The GSM-batcorder can be equipped in such a way that it allows monitoring at height of lower blade tip from within the turbine mast. This is especially useful when working at modern turbines with large rotor diameters thus allowing inly partial acoustic detection from the nacelle. With our mast microphone, the first of its kind, you can easily monitor from within the mast. Of course, a small whole needs to be drilled.
