After making one of Qrome's awesome print monitors I noticed how similar in size the OLED module and a PIR sensor I had to hand were. So instead of reinventing the wheel and creating a new body for the motion sensor I remixed Qrome's casing.
I had to extend the case lengthways to incorporate a slightly bigger Wemos d1 mini board (34.5mm) and also had to extended the height to fit the HC-SR501 PIR sensor. I put screw holes in to screw the PIR to but It pretty much friction fits in place with no glue or screws needed.
I'm using mine for a motion sensor for Philips Hue but it can be used for whatever you feel like.
For anyone who wants to try:
I used the code from here: https://github.com/LeskoIam/esp8266Huemotion
I added an ntp server to the code. I'm using uk.pool.ntp.org so search for this line and replace with your region.
It will turn on a light (or group of lights) full brightness between 5pm and 12am and 45% brightness between 12am and 5am.

You will need to register a user on your hue bridge. Details of how to do this are listed here along with basic usage of the hue api: https://developers.meethue.com/develop/get-started-2/
My code uses the user "newdeveloper" as per the hue getting started guide.
