HC-SR501 PIR wall mount
thingiverse
It's a housing for an HC-SR501 mounted on a small perfboard. Two holes accommodate 3mm screws, allowing it to be securely fastened to a wall or cupboard. A female micro-USB connector and a female USB-A connector are present alongside some connectors and a relay. When the PIR is triggered, the relay instantly switches off the 5V connection between the USB connectors, keeping it off as long as the trigger persists. This action activates the display on any connected tablet by disabling the 5V power supply. You'll need to scale down the design to 10% before slicing for successful printing. Print Settings: Printer: Geeetech I3 X Acrylic Rafts: No Supports: No Resolution: 0.2mm Infill: 50% Notes: A small brim might be necessary, depending on the specific print requirements.
