	Wind Data Logger The Wind Data Logger is designed to provide an affordable and easy-to-use solution to wind site evaluation and monitoring wind generator performance. It records wind speed, gust, and direction, time and date, temperature, battery voltage, and other important wind parameters. The Wind Data logger easily supports both simple and complex monitoring applications. The data logger can be used to record wind speed from a single anemometer, or it can be used for complex studies involving multiple wind instruments and other sensors. The Wind Data Logger records directly to a Secure Digital (SD™) card. No special computer interface cables are required and the software can easily be viewed and analyzed using standard spreadsheet software. Using custom and off the shelf hardware and software, APRS World can build whatever data logging system you need. We supply simple systems for wind site analysis and complex data logging systems with many sensors and live data streaming to the Internet.
	APO3: Automatic Power Off Device APO3 is a black box designed to prevent a vehicle battery from being discharged and damaged by a DC load. Typically, it is used to switch a radio transceiver off 10 minutes after the vehicle is shut off. This is for use with mobile APRS stations. It allows the radio to transmit a few position reports after the vehicle is shut off and then it turns off the radio and GPS to reduce clutter on the APRS channel and prevent the vehicle battery from discharging.
	Wind Monitor II The Wind Monitor II is a basic wind speed display and data logger for a single anemometer. It is designed for wind generator monitoring and site analysis. It features an easy-to-read green LED display that shows the wind speed. When used as a data logger, it can record up to 32,768 instantaneous wind speeds to its non-volatile memory. For programmers and hardware hackers, the source code is available under the GNU GPL license.
	Sensors and Sensor Accessories We offer a variety of sensors including: Anemometer used by the Wind Data Logger, Wind Monitor II, and WrenDAQ Wind Vane used by the Wind Data Logger, Wind Monitor II, and WrenDAQ Temperature used by and included with the Wind Data Logger Temperature, Relative Humidity, and Light used by the Wind Data Logger and WrenDAQ Sensor accessories include: Tee used with the anemometer and wind vane Mounting Arm used with anemometer, wind vane, and tee PVC Bracket used with anemometer, wind vane, and tee RJ-45 Breakout Board used with all of our sensors RJ-45 Splitter used with all of our sensors
	WrenDAQ The WrenDAQ is a compact, turbine top data acquisition unit. It is designed to collect critical performance data for small turbine developers and testers. The WrenDAQ uses a license free 900 MHz data modem to transfer data to your PC. Because the WrenDAQ is powered by the DC voltage from your turbine, there are no additional cables to run; this allows adding data acquisition without adding additional slip rings for the signals. The WrenDAQ was developed to meet the needs of one of our customers. We can produce a custom or semi-custom WrenDAQ to meet your exact needs. Please call or e-mail and we will be happy to discuss your needs and give you a quote. We are also pleased to offer you with the WrenDAQ schematic, mechanical information, embedded software, and other technical information so that may make the modifications you need - or even make your own WrenDAQ.
	Wind2DB Wind2DB is free software for monitoring, logging, and broadcasting data from you Wind Data Logger or WrenDAQ. The software is written in Java and can run on Windows, Linux, Unix, or Macintosh computers.
