Bat Acoustic Data Logger Predicts Seasonal Changes of Bat Species

eTradeWire News/10658453
CLEVELAND - eTradeWire -- Grouse Mountain Environmental Consultants deployed the dataTaker DT82i with a Wildlife Acoustics bat recorder to capture and transmit survey data. The bat recorder captures ultrasonic bat calls, which Grouse Mountain processes to determine species presence on a monthly basis. Collecting this information is recommended for two years prior to development of wind energy per the US Fish and Wildlife Land-based Wind Energy Guidelines. Bat acoustic data indicates the presence and seasonal changes in species occurrence, which is then used to provide a prediction of the potential risk of bat fatalities resulting from future development.

Installation

A key component in the system is the Wildlife Acoustics SM4BAT FS Ultrasonic Recorder. It's specifically designed to capture and record the ultrasonic "chirps" made by bats. The SM4BAT is housed in a weatherproof enclosure and in this application is externally powered to allow continuous operation for an extended period of time.

A dataTaker DT82I data logger was used to capture and record the statics via this RS-232 interface. While the logger has an internal rechargeable battery, a 10-watt pole-mounted solar panel with Sunsaver charge controller and a 12V 10 A-hr. battery were used to provide continuous power year-round.

Usage

In this application, the customer was most interested in the daily statistics so the logger was programmed to read information from the SM4BAT once a day via the RS-232 port. It also read its own internal battery voltage and the voltage of the external battery to help provide data to help manage the system. This data was stored in the logger's internal memory providing a backup in case there was ever an issue with the data upload via the modem.

A key to the operation of this system was minimizing power consumption to allow continuous operation off just the solar panel. The logger was programmed to go into a sleep state whenever it was not taking a measurement or sending data.

Benefits

The key benefit of this setup is that the data is sent automatically, so the customer doesn't have to visit the site. The battery voltage data allows remote diagnostics for potential issues like dirt on the solar panel. This daily check-in provides the operational status of the SM4BAT recorder, which is in an area of Montana subject to harsh winter conditions. Grouse Mountain sincerely appreciated the responsive and professional tech support from CAS during the development and deployment of the dataTaker solution to resolve any issues while the staff was on-site.
