Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

This is a simple update to Mr. Hareendran’s PIR Sensor Security Light circuit. It has a shortcoming limits the relay voltage to approximately 3.3V. While this may function with some 5V relays, it will ...

Movement-based lighting suggests activity inside, which helps deter opportunists. Automatic light on stairs, landings and entrances reduces falls and avoids leaving circuits on. Hands-free access ...

California-based KODA’s latest security camera introduces its first motion-activated floodlight + alarm offering with the new KODA LightCam. The camera includes some impressive features including the ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...
