It happened many times - we are in the saloon, either in a marina or on anchor, and then someone asks: how strong is the wind? And I have to go to the cockpit, switch on an instrument and read the display. In order to simplify this and get all the boat data in the display of my smartphone, I developed Nmea2Wifi. I am selling this module on Ebay, You can buy it through Ebay by clicking in the following animated image or you can contact me directly by email (see the Home Page).
The module allows you to display your boat and navigation information on your smartphone, tablet or laptop computer though wifi. The system has 2 opto-isolated full Nmea 0183 compatible input ports.
One port is used to receive all the instrument data at the rate of 4.800 or 9.600 baud. The other port has an adjustable baud rate of 4.800 up to 38.400 baud (and so it can receive AIS data). The 2 streams of data are combined and transmitted over wifi to connected receivers. In addition the module can also send data through an output serial port with selectable baud rate. You can use this module in different ways. You can use it to transmit your boat data to a PC running navigation software such as OpenCPN or you can use it with several free apps for Android or Ios. One possibility is to use it with SeaWi to get a backup of the information available at the main chart-plotter and with Navionics Boating HD to get Sonar Chart Live maps. Here is a video by Navionics:
