This repo describes the modification of a Ventus W132 replacement wind sensor, so it can send the NMEA 0813 information wirelessly or the NMEA 2000 via a CAN BUS.
The original sensor for the angle gets replaced by an AS5600 magnetic orientation sensor to achieve a better resolution.
The computing an wireless transmission of the NMEA Datagrams as well as the web interface is done with an ESP32.
The NMEA 2000 data can be send via an SN65HVD230.
The modification reuses as many of the original components as possible, so that, theoretically, only a few parts are needed:
- an ESP32
- an AS5600
- a chamfered 5mm spring pin
And, for NMEA 2000,
- an SN65HVD230
- fur jumper wires
All the other components are taken from the original sensor. That reduces the overall costs to approximately 40€.
The firmware can either work standalone, where the sensor creates an access point that can be used to display the data on a tablet or phone without any further hardware, or be integrated in an existing setup.
This project is a continuation of the NMEA0182-Windsensor-project.
The firmware can either connect the sensor to an existing network or create an access point. It has a graphical display of the data and a settings page in English and German.
