5PCS PIR Motion Sensor Module For Arduino - Human Infrared Detector With Dupont Wires

Got an Arduino, Raspberry Pi, or DIY electronics project? These PIR (Passive Infrared) motion sensor modules are super handy. They detect human movement (body heat) within about a 7-meter range and a 120-degree cone. You get 5 modules plus a 15-pin Dupont cable (female to male) for easy wiring. They work from 4.5V to 20V, use very little power, and output a 3.3V high signal when motion is detected. You can adjust the sensitivity and the delay time (how long the signal stays high after detecting motion) with the little potentiometers on the board. Perfect for building automatic lights, security alarms, fan controllers, or any project that needs to \see\ people. They need about a minute to start up after powering on. A must-have for any maker's toolbox.
