How to properly link an Arduino and its sensors To finalize a prototype, I would like to have a proper structure containing the arduino (uno here), its shields and its sensors. I would like the sensors to be soldered to the arduino+shields block, but the sensors were sold on a small separate PCB (example).

What is the recommended method to have a strong, clean link between the two ?
You could solder those modules to a prototype shield.  If you replace the header with a right-angle one (or even just bend the pins on the existing one) you could even mount it vertically to save space.
