Description: 1. The HC-SR505 Mini PIR Motion Sensor is a passive infrared (PIR) motion detection component widely used in home automation, security systems, and DIY projects. 2. It features a small form factor, measuring only 2 x 2 inches, making it ideal for applications where size matters. 3. This sensor can detect body heat and motion within its field of view (FOV) with a detection angle of approximately 110° x 60° and a maximum detection distance of about 8-12 feet. 4. The HC-SR505 operates on a simple principle: when it detects a change in heat within its FOV, an output signal is triggered. 5. It comes with adjustable sensitivity levels to accommodate various lighting conditions and minimize false triggers (daytime light or pets). 6. The sensor has three pins: VCC (+5V DC), GND (ground), and OUT (signal output), making it simple to connect and integrate into various projects using a microcontroller or other electronics. 7. One unique benefit is its ability to be used in multiple applica
