RE: Wind sensor alternatives to FineOffset. Any ideas?
Is there any interest in support for Lacrosse wind sensors (I happen to have some). I notice that John Geek from New Zealand has fully reverse engineered the interface and protocol.
https://www.john.geek.nz/2011/07/la-cros...-protocol/

Adding support for devices which have its own RF transmitter system it's difficult, each one use it's own frequency, or modulation mode, which may not be compatible with WeatherDuino Pro2 receiver.

The Lacrosse uses a wired serial path between its wind sensors and it's outside sensor unit. The only issue seems to be decoding and parsing the serial data blocks (probably beyond my capabilities though).

I am about to order some wind sensors. I conclude that the best high end solution for wind measurements seems to be the VORTEX 8-Pulse High Resolution Anemometer, and the Inspeed E-VANE2 Electronic Wind Direction Sensor, does anyone have any information to the contrary?

I just can say they are really good, and they work with the WeatherDuino Pro2 system. I'm using them since one or two months.
The software with support for the Inspeed Anemometer and Vane, is not published yet, but there is already a Beta version available for testers. When you get them, just tell me.
To use them with a TX v2.50 board, some small modifications are required.
I'm planning make available a small adapter board (at very low cost, from 4 to 5€), which will make the connection between the Inspeed Instruments (and others) and the TX board, really easy.

Thanks for that.

Just some info about what is going on in this matter.
WeatherDuino Pro2 v1.5, is already in beta2 state.

Here is another anemometer / vane that someone may consider. As it is a direct replacement for the Davis then it should work assuming the pinouts are changed from Davis on the RJ11 to the TX RJ12 mentioned in previous posts.

Impressive, an Ultrasonic Anemometer for Davis weather stations!
Yeah, if it works with a Davis, it should work with WeatherDuino Pro2 too.

Just for curiosity, do you have any idea about the price of this toy?

Fell free to create the new thread .

Hi
Would it be possible to use a wind sensor such as the WSD1 from Environmental Measurements Ltd
This uses a continuously rotating potentiometer which could be connected as a voltage divider circuit.

Thanks

I think they are GBP 330.00 but!! https://code.google.com/p/mysudoku/downl...p&can=2&q=
For a challenge.

Hi,
I plan to use my old WM918 wind sensor, the schematic is similar to the davis 6410(20k pot.).
   
Could someone give me the wiring to the RJ12 TX unit please ?

Thanks

Your anemometer / vane is not directly supported, but using this wiring it should work.
For your anemometer, you may also need to know the wind speed correspondent to 1 click / revolution, and make the necessary changes in the software.


TX board wind RJ12 connector

Pin3 (GND, for anemoter and vane) - GN Vane, RD Anemoter
Pin 4 (Anemometer) - WH Anemometer
Pin 5 (Vane, from variable resistor) - BK Vane
Pin 6 ( 5V, for vane) - RD Vane

Don't use R4, C2 and C3

I have available this small board adapter, which allow an easy connection between almost all kinds of supported wind instruments (and others, as we are seeing) and the WeatherDuino TX board (any version).
