Description
This IR motion sensor relay switch circuit is designed for use with all kinds of medium-power automobile/domestic 5V DC loads. It is a simple solid-state relay (SSR) switch, controlled by a standard passive infrared (PIR) motion sensor module. A PIR sensor is an electronic device that can measure IR light radiating from objects in its field-of-view.
Circuit diagram of the IR motion sensor relay switch is, its built around a PIR motion sensor, BC547 (T1) and IRF9540 (T2), rectifier diode 1N4007 (D1) and a few other components.
