Products

Many of our products are available for purchase directly through our sister website. Just look for this symbol in the product description:

	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. Not only can the data logger be used to record wind speed from a single anemometer, it can also 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. The Wind Data Logger is available in modules and packages and in self-contained systems for outdoor use.
	ThermokSolar The ThermokSolar-4A is a solar heating differential temperature controller for PV and DC powered applications. It is configured with four temperature sensor channels, an LCD display for real-time view and easy programming, and two solid state DC relay outputs. Designed to run directly from a PV panel, the ThermokSolar-4A is unique in the industry in that it requires no outside power.
	ThermokLogger The ThermokLogger-4A is designed to provide an affordable and easy-to-use differential temperature controller for solar heating systems. It is a four channel 10K thermistor display and data logger with programmable solid state relay outputs.
	Production Logger The Production Logger is an integrated data logging system for measuring grid tied renewable energy system input and output. An anemometer or solar radiation sensor alone can measure your available input resource. A kilowatt meter can measure system output. But only when you combine your available resource and your actual produced energy do you get the whole picture. Add the optional Internet module and you can view your system performance with just a web browser. Just plug in an Ethernet cable and your data will automatically appear on our website: data.aprsworld.com. Standard web displays are available or we can customize your website to meet your exact needs.
	Crane Wind Logger Data logger records wind speed, wind gust, and average wind speed at one minute intervals. Data is downloaded wirelessly from a laptop computer running the supplied software. Logger and anemometer mount on crane boom. No cables to run.
	Sensors and Sensor Accessories Weather Sensors: Anemometer -- a sturdy sensor for cost conscious measurement. Anemometer, #40R -- an improved version of the industry standard #40 anemometer. Wind Vane Temperature Temperature and Relative Humidity -- low cost and accurate. Solar Insolation -- light intensity sensor for weather stations and solar site survey. Rain Gauge Sensor Mounting Accessories: Mounting Arm used with anemometer, wind vane, and tee PVC Bracket used with anemometer, wind vane, and tee Wiring Accessories: RJ-45 Breakout Board used with all of our sensors RJ-45 Breakout Board to Screw Terminals, DIN Mountable used with all of our sensors RJ-45 Splitter used with all of our sensors Anemometer and Wind Vane Splitter Board allows up to three anemometers and a wind vane to be connected to the Wind Data Logger using normal CAT5 cables. Electrical Sensors: Wind Turbine Speed Sensing Circuit for extracting 0 to 5 volt frequency from high voltage AC generator output. Masts and Booms: Masts Booms
	DL300: Dump Controller and Load APRS World's DL300 series dump controller and load is an integrated solution designed to prevent 12 or 24 batteries from overcharging. It is designed to be used with small wind, solar, or hydro system. the DL300 is compact and easy to install. It incorporates a 300 watt resistor / heater for easy installation.
	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 ideal 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.
	WrenDAQ3 The WrenDAQ3 is a compact, turbine top data acquisition unit. It is designed to collect critical performance data for small turbine developers and testers. The WrenDAQ2 uses a license free 2.4 GHz Zigbee (802.15.4) data modem to transfer data directly to the Internet or your PC. Because the WrenDAQ3 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. For educational and demonstration projects we are pleased to offer a combination of Chinook 200 Wind Turbine + WrenDAQ3 that is pre-wired and ready to go. This is the ultimate small wind teaching tool. A micro wind generator that is easy to understand and see operating. And fully instrumented so you can measure and observe exactly what it is doing. 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.
	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.
	XBee-PRO RF Modem with USB Interface Digi International makes a wonderful line of 802.15.4 XBee modems. They are fast, power, and reliable short range modems. The only downside to the modems is that they aren't readily available. Often the lead times are 6 weeks or more. Faced with too long of lead time and a short-deadline project, APRS World designed our own external USB modem that uses a Digi XBee-PRO modem. This production functionally similar to Digi's XBee-PRO PKG modem package. Our XBee-PRO modem is perfectly compatible with Digi's -- because we use a Digi RF modem module. USB interface is provided by an FTDI FT232RL USB to serial converter IC.
	DC LED A beautiful white LED light for 12, 24, and 48 volt DC applications. 3.5" diameter anodized aluminum and frosted glass body looks great in home and industrial applications alike. Perfect for under counter lighting, but also great for task and room lighting.
	Books Our favorite books about wind power. For anyone who is interested in a wind project these are required reads.
