How to Build Your Own Anemometer Using Reed Switches, Hall Effect Sensor and Some Scraps on Nodemcu. - Part 1 - Hardware

Step 8: Connecting Nodemcu and Installation

The diagrams show the correct connection of each cable.
To test the operation I used a 0.96 "OLED screen to read the measurements and verify that they are correct, connect the OLED in this way:

D1 - SCL

D2 - SDA


To install on the ceiling the only care is to keep the whole device at the correct level. For that use a bubble level and many large screws. And do not forget to address the north of your anemometer for the geographical north of your compass. Otherwise, the direction of the wind will not correspond to reality.

And that's all. In the next post, I will explain the sketch to be loaded in the nodemcu using Arduino IDE.

If you have any doubt, do not hesitate to contact me.

Looks like a good project. I wonder if using hall sensors instead of reed switches would be worthwhile? I realize you have to add a/d functions but then you might not care about higher resolution of wind dir. Just a thought. Well done in any case.
