PIR HC-SR501 sensor adjustable wall housing

thingiverse

This is my PIR HC-SR501 housing featuring two wall mount options, each offering a unique level of adjustment. One simple mount allows for 360° rotation up and down, while the other includes an almost 180° left to right adjustment option. The box itself consists of two parts: front and back, which fit together precisely and are held in place by attaching the wall mount holder over small side buttons. No screws or glue are needed unless you want to make it waterproof, in which case I recommend using a silicone sealant. Additionally, the front part has a small tube hole around the PIR lens where you can fit a sun shield if used outdoors. I've created two types of shields, but feel free to design your own by using the "dummy" half globe provided - simply make a hole or create a 1mm thick, 26mm outer diameter tube. A dummy PIR object is also included, which you can use as a reference point for creating your own box or making adjustments to my design. The dimensions of this housing are tailored to fit the HC-SR501 and may require bending some contacts if you're using a connector. Cable holes aren't included, but feel free to add them anywhere needed. Printed with PETG, the rotating parts may rotate slightly stiffly at first, but twisting them a few times will smooth out the edges and allow for smooth rotation. Enjoy!
