HowTo: PCB - Building the Anemosens Sensor PCB

The Anemosens sensor PCB is the basis for the sensor setup of Anemosens a 3D printed anemometer that I developed for the second version of WinDIY.

Dazu sind auf dem PCB ein AH49E Hall-Sensor und ein AS5048B I2C 14 Bit “magnetic rotary encoder” verbaut. Der AS5048B dient dabei der Bestimmung der Windrichtung. Mithilfe des AH49E Hall-Sensor kann man die Windgeschwindigkeit messen indem die Zeit einer vollständigen Umdrehung der Windschaufeln gemessen wird.

To assemble the PCB, it is divided into two parts at the prepared points and soldered together at a 90° angle. The finished PCB can then be installed in the 3D printed housing from Anemosens and fixed with three M2x6 screws.

I bought the board from the board manufacturer PCBWay.com which has provided me with these free of charge. At this point, thank you again for the great service and cooperation 🙂.

In the following you can see some pictures of the finished board and all possible components.

Safety instructions

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.

Requirements

For the assembly you have to master SMD soldering tasks. The following articles contain tips for this.

• Electronics - My friend the soldering iron
• Electronics – Solder THT components by hand
• Electronics – Solder SMD components by hand

The structure

In earlier projects I have inserted single pictures at this point to show which components have to be soldered where on the PCB.

An even better way to get an overview of which components belong where on the PCB is shown in the following paragraph. Thanks to the work of OpenScope Project you can now generate very helpful HTML files in which you can directly see which components have to be installed where on the PCB.

You can see the overview for the Anemosens sensor PCB here: Anemosens Sensor PCB

The current file can also be found in the GIT repository under the following link:

(Please note that you have to download the HTML file to view it. Directly from the GIT repository this is not possible).

Program firmware

The firmware for controlling the sensors on the Anemosens sensor PCB in combination with the Anemosens_MCU PCB is still under development. You can see the current status from the GIT repository download. You can find the firmware at the following link.

Have fun with the project

I hope everything worked as described for you. If not or you have questions or suggestions please let me know in the comments. I will then add this to the article if necessary.
Ideas for new projects are always welcome. 🙂

PS Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you think it's cool that I share the information with you, I would be happy about a small donation to the coffee fund. 🙂
