Anemometer & Vane Tester
« on: July 05, 2015, 08:27:39 PM »
I have designed and produced one prototype of the Anemometer and Vane Tester.  This will be a DIY project.  You can build your own anemometer and vane tester.  The 1st prototype is 2.5 inches by 3.8 inches.  I'm reducing the board size to 1.9" x 2.5" to reduce cost.  I estimate the total parts cost to be less than $30.00.
I have tested it with the reed switch version of anemometer.  I will make this compatible with the Hall sensor version of anemometer.
This tester has 3 functions.  1  It has the wind cable tester circuit that Davis provides.  2  It has an Ohmmeter breakout for measuring the potentiometer and switch closure using your Ohmmeter.  3  It has a circular pattern of LEDS that indicate rotation of the direction vane and a LED that flashes as the cups rotate.
It is self powered by two AA batteries.  It has a cable that plugs into the Davis ISS SIM board wind socket.  It has two connectors that the anemometer/vane plugs into.  You can test your anemometer from the ground where your ISS is located.  You can test an anemometer on your work bench.
I will publish the schematic, parts list and circuit board pattern if you wish to build everything.  I will offer a kit of parts and instructions.  Enjoy,  Al

What a great idea for a project..........I'm interested, love tinkering with electronics, one hobby that gives great satisfaction from seeing a pile of electronics parts transformed (pardon the pun) into something that works and actually has a use.

I'm excited that George Wetzel, our Peachtree City, Ga. NWS Observation Program Leader visited my wx station today.  I was able to show off the a/v tester and its flashing LEDS.  He was here when UPS delivered the new Davis anemometer.  It'll be in pieces by the weekend.  I'll take o'scope signal pictures before I destroy the new anemometer.
I plan to check compatibility with the Hall sensor wind speed circuit before I release the a/v tester schematic.  Pictures and data should be ready by the weekend of 11-12 July.

Very cool project :) It can function as a rough wind direction sensor too :)

I'm eager to see what the new anemometer holds inside!

Success and delay.  I modified the tester to apply 1.25 volts to the anemometer and vane under test.  This tester is compatible with the anemometer and vane that uses a reed switch.  This tester is compatible with the anemometer and vane that uses a Hall sensor.  As we knew, an Ohmmeter can't measure the Hall sensor signal.  However your multimeter set to measure AC millivolts will detect the Hall sensor output.  I'm presenting the device design to an electronics supplier for them to kit the parts including my plans and images.  I'll publish the schematic, parts list, and pictures here next week.  You can then buy the kit or do it all yourself.

A forum member asked for instructions to build your own wind test/diagnostics cable.  Here is my version.  It uses a 20K Ohm linear potentiometer instead of the two 10K matched resistors in other designs.  The Davis test cable will produce an S reading on the console.  With this pot, you can crank and watch the console respond with N to E to S to W to N.  Repeatedly pressing the push button gives wind speeds up to about 20 mph.  Attached is the schematic and 3 pictures showing the front and back wiring.
Parts:  4 conductor telephone type cable
crimp on connector 6P4C or RJ-14 type (a crimping tool is needed for this connector)
20K linear potentiometer
spst momentary push button switch
The anemometer and vane tester described July 5 - 10 is in the second prototype stage.  Dale is working on this project also.

Old topic, but still interresting.
Is there still a schematic, parts list and/or circuit board pattern available?
I would like to build this A/V tester and especially the Hall sensor version.

Thanks,

I have versions of this project and today I'm clearing my workbench to finish this project.  I'll have the board design with ExpressPCB, parts source, a parts kit, or a completed 3-part anemometer tester.

PROGRESS REPORT:   This is an update on the anemometer vane tester project.  You should allow me time to build this board design and test it before you invest your time and money on these ideas.
I revisited this project and have completed a better design.  I will start a new topic to be less confusing.
I am posting the schematic and an image of the circuit board attached here.  The circuit board contains two testers to save on cost.   The 'cut here' comment on the circuit board means to use your fine saw and cut the board into 2 identical pieces.  Each piece is a complete av tester.  (av means anemometer vane).
If you prefer, you can copy the schematic into ExpressPCB design application and purchase your own boards from them.  I assume no responsibility for errors or damage caused to anything from using this information.  I will provide a multipage instructions document for building and using the anemometer and vane tester.  This device works on the original reed switch and the newer Hall sensor version of the wind speed circuits.
Good luck building the project.  Al

Hello Al,

how is progress with the BOM of the anemometer and vane tester project?
Or is it possible to order a kit with pcb and parts to build one from you?

Funnily enough I was was playing with this earlier today, I did get all the parts a few months ago, but had a tidy and and now can't find anything :-)

I've changed the display to be a bargraph as its easier for me to make on a single sided PCB, the image attached is the provisional design, not yet tested and drawn in Visio.

I'm assembling a board today.  One connector is on the wrong side.  If this board works, I'll let someone try assembly of a board.  I know the design works.

I'd be happy to buy a board and make one up.  I have soldering skills.  I've made the Blitz lighting boards when they were self build.

I also have a "spare" anemometer I could use.  I just replaced mine as the bushings were shot.  So it reads about half wind speed, but right direction.
