Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism ... LEDs through a solid-state switch realized using transistors T1 & T2.

By using these readymade and pre-configured PIR sensors ... High level output (3.3V) of pre-settable variable width (5Secs -18 Minutes) is provided. Circuit diagram of the PIR Motion Sensor Light and ...

As a perfect example, take a look at this stupendously simple Internet-connected motion detector that [Eric William] has come up with. With just a Wemos D1 Mini, a standard PIR sensor, and some ...

Using motion detectors and an Arduino ... LOW); delay(500); } } Here is the circuit for the Sparkfun Active Low style sensor. PIR Pin “+” connects to Arduino +5 one side of the ...
