AnemoSens - SLA printed anemometer

This is my design of a SLA printed anemometer

When I started with my own SmartHome, one of my first projects was my own small weather station (Small insight here: to monitor weather data.

Sensing the temperature, air pressure, air humidity and co was relatively easy. For example, with the BME280 you can record all values with just one sensor.

One problem that I couldn't solve until the end is how to record data about the wind, i.e. wind speed and direction. Of course, you can buy matching sensors. However, I always found them too expensive or big. If you wanted to use a compact sensor without taking up a lot of space, you almost always had to dig deep into your pocket.

That's why the decision to build my own compact wind sensor had long been made for me, but so far I haven't gotten to it.

For the construction of WinDIY_2 ( I was faced with the problem again that I needed a cheap and compact wind sensor. That's why I started to develop my own. :)

  • First prototype of Anemosens

    The first prototype is finished. Please see the pictures and the video for further details. :)

  • Finished the sensor PCB

    In the meantime I have also created the circuit board for the Anemosens sensors and completed the first tests.

    A Hall sensor (for detecting the wind speed) and an AS5048B rotation angle sensor are located on the circuit board.
    With the latter, the direction of the wind can be determined.

    As always, you can see more details in the pictures. :)

  • Slightly adapted design

    Fab08/01/2021 at 12:43 0 comments

    The design of Anemosens is now quite finished.

    I made the tip a little "sleeker" to show the wind direction. In addition, the base has also become a bit more compact.

    The circuit board including sensors will also be housed in the base :)
