🚀 Why It’s Ideal for Your Projects

• Easy object detection – The module triggers when an object comes into range, allowing you to detect obstacles, edges, or approaching items without complex setups.

• Adjustable sensitivity – With a built-in potentiometer, you can fine-tune the detection distance to suit your specific project, whether for close-range or farther sensing.

• Microcontroller-friendly interface – Operates from 3.3 to 5 V and provides a clean digital signal output (active low) that plugs directly into Arduino, ESP32, Raspberry Pi GPIOs or other controllers.
