Wind Sensors

[BellaX]

Hi all,

I've been searching a lot for a wind sensor that I can use with OP. It appears that the Tindie decoder for the Peet Bros sensor isn't available anymore (although I'm not sure I want a Peet Bros sensor).

What is everyone else using? Anyone tried an ultrasonic sensor? Are sensors like those that come from Davis robust enough to be used on the masthead?

Hi abarrow,

have you seen this one?

It uses the Peet Bros principle, a rotating magnet, metal shield and two hall sensors. The plastic parts can be 3d printed.
He uses a ESP8266 for the processing and wlan to send the wind data to OP. I have got one of his prototypes for just
25 EUR.

One very clever idea is to reuse the existing cable for the anchor light. The white led will not light below seven volts.
If you put six volts to the anchor light it powers the wind sensor with 6-12V -> 3.3V regulator placed inside the anchor light 
housing. If you enable the anchor light the leds get 12 V and start lighting. The wind sensor keeps running.

I have built a windvane around four years ago. It uses a BLE112 bluetooth module from Bluegiga. I have connected a
four quadrant magnetic sensor that measures the angular position of a diametral magnet. The angle is sent via BLE
advertising packet to the RPi. This means there is no permanent connection needed and the power consumption is
very low. A CR2032 battery lasts three to four months at one reading per second. I am using node-red to receive the
data and convert it to a nmea string. It then goes via UDP to the OP port and can be displayed using the standard
dashboard for the wind vane.
