Introduction: Lego PIR Housing 6x6
First of all, I want to thank tocsik for his Lego PIR Housing that I used as a starting point for my housing. My PIR was slightly bigger than the one tocsik used, so I had to increase the size a bit. I also don't like to modify my bricks, so this instructable doesn't have any brick modifications.
Below, the steps are taken from Lego Digital Designer.
Step 1: Parts List
Step 2: Build the 'Front'
Step 3: Build the 'back'
Step 4: Put It All Together
Step 5: Final
This modified version of the Lego PIR housing allows the sensor to be moved around inside the housing, but still nice and tight.
The cables come out the bottom, and depending on the connector, you may need to increase the size of the bottom by one or 2 plates
