Enclosure for HC-SR501 PIR sensor board

This simple enclosure is created for HC-SR501 PIR sensor board. It is specifically designed to blend seamlessly with the interior decor and to provide elegant solution for your security system sensors. The main goal was to combine ease of installation and maintenance with some aesthetic appeal.

Key Features:

• Simple installation: The mounting plate could be fixed with a single screw on any of the two walls or even the ceiling. There is a cut-out section for the cable harness. To simplify the fitting process, you can plug the mounting plate into the enclosure and place the whole assembly in the desired position. Then mark the drilling point through the PIR sensor opening (use the last picture for reference).
• Easy maintenance: The enclosure is easy to install and easy to remove, since the mounting plate slides quite freely. When unmounting, you can use the help of a tiny hook or painter's tape. It is a good idea to clean up the sliding surface before the initial mount.
• Optimal sensor placement: Positioning the PIR sensor in the upper corner of the room maximizes its motion detection capabilities. It might be necessary to prepare a second sensor when placed in long and narrow rooms.
• Visible surface: To ensure a perfect match with your room's decor, the enclosure could be painted. You can customize it to match your wall color to achieve a truly seamless integration.
• Cable management: It is designed with built-in service holes on both sides of the circuit board, the enclosure ensures efficient cable management, keeping wires neatly organized and out of sight.

Important information:

• It has been tested with several HC-SR501 boards from different providers. To ensure better fitting, you can rotate the board or bend the electrolytic capacitor leads.
• It is designed for rooms with perfect 90-degree corners. If your walls and corners aren't perfect, some noticeable gaps will appear
