Unfortunately, real-motion detection requires rather more sophisticated and thus more expensive sensor. However ... is usually done with the help of a microcontroller. HB100 outline diagram and ...

High level output (3.3V) of pre-settable variable width (5Secs -18 Minutes) is provided. Circuit diagram of the PIR Motion Sensor Light and Switch based on SB0061 shown here can be used for security ...

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 ...
