This enclosure is engineered for a precision fit around the standard HC-SR501 sensor module.

• Design & Material: The case features a minimalist cubic design, likely printed in PLA or PETG. The bright yellow color makes it highly visible for industrial or experimental setups.

• Aperture: A circular cutout on the face allows the translucent Fresnel lens to remain unobstructed, ensuring a full $120^\circ$ detection angle for infrared heat signatures.

• Features:

  • Side Port: Includes a rectangular cutout on the side for easy access to the sensor's sensitivity and time-delay adjustment potentiometers.

  • Mounting Tab: A built-in eyelet/tab at the base allows for easy screw-mounting to walls, ceilings, or chassis frames.

  • Cable Management: Rear exits provide a clean path for the VCC, GND, and OUT jumper wires.

• Application: Ideal for securing sensors in motion-activated lighting, security systems, or energy-saving projects where loose wiring needs protection from dust and physical impact.
