About this project

This object measures humidity and temperature to help you avoid unhealthy air quality and problems like very humid or dry air and mold growth.

The object changes its color accordingly: from blue for good air quality to yellow, orange, and red for poor air quality.

This is a fun and easy project to build. It helps remind you to open your windows regularly and makes your home a healthier place. You can also add more sensors to measure dust, CO2, and other things.

The project emerged from my bachelor thesis project in design at Munich University of Applied Sciences. It was created in collaboration with Tado°.

You can check out the entire project here.

Breathing on the sensor to demonstrate the functionality

Abitaboutmyprocess:

I used paper straws and ping pong balls to build the object. The ping pong balls create nice and dim colors.

Sodering RGBs LEDs to the cable pieces so they will fit into the straws.

I decided not to control every LED individually but in groups of four to create a easier set up. This means four LEDs are connected to one pin. You can learn how to do this here.

Putting it all together...

Adding the ping pong balls at the end.

The result:

I used a wooden box to store the boards and a simple power bank. By breathing on the sensor I could test how it works.

Thanks for reading and let me know what you think. :-)
