Hello,
I have found many interesting projects here. Now I would like to introduce my own project.

Since my experiments with MySensors were quite successful on the breadboard, I decided to design a productive device with it.

It should be a motion detector with light intensity measurement.

Building prototype.

I have permanently installed the unit in a flush box.

After some time, the whole thing has worked well. I have decided to equip other rooms with these devices. However, it should be a bit more professional.
Therefore, I have designed my own PCB with Eagle CAD.

The PCBs were manufactured by ITead.

Step by step assembly of the device.

The Eagle and the firmware files for the modules can be found in my Github: https://github.com/hexenmeister/MySensors_MyDevices

regards,

Alexander
