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
