The sensor package of OpenWind includes: AWA /  AWS, compass and pitch / roll. In Addition to that, our application calculates COG, SOG, VMG, AWD, TWD, TWS, TWA and rotating mast angle compensation. The SOG and COG are calculated from the phone’s GPS and used in formulas such as TWS.

Yes you can mount it directly on the mast. OpenWind is designed to never run out of battery, you only switch the power button ON once and the device is self sufficient. We use bluetooth low energy  technology and has a range up to 50 meters with no connection problem.

OpenWind is compatible with NMEA protocol via our NMEA kit device.

The usual half sphere cup anemometer measures differently depending on the angle of heel. The design of the blades from the OpenWind anemometer can measure more precisely with angle variation. In addition to the integrated 9 axis sensor we also correct any small decimal variations. The innovative wind cup design is used under license from SailTimer Inc. www.SailTimer.co

OpenWind only connects via Bluetooth, as it is designed to be a low power consumption device and Wifi demands a lot of energy to run.

The “open” mean it is open to most smart devices available on the market, so sailors that have no marine displays or a battery on board can still have wind information by simply using a smartwatch, tablet, or smartphone. We have a developers kit for whoever wants to program your own system (in a raspberry pi for example). 

We have a solution for rotating mast angle compensation. OpenWind has an in-built compass and our application takes in consideration the compass variation between phone and the OpenWind to give you the correct heading and wind direction. For it to work properly, the phone needs to be mounted on the boat aligned with it’s heading.

The NMEAki™ with in-built compass can also compensate mast rotation.

Restart the application and try to connect within 50 meters.

If the device blinks red when switching it on, but it is not blinking blue every 10 seconds it means the battery is low. Leave it on the sun until it blinks blue, then try to connect it again.
