Passive Infrared Sensors (PIR) are easy to use and set up. You can use them to control home automation devices including lighting, alarms and door openers. They are great for power and battery saving, making sure that lights (or anything else...) turn off when nobody is around.
In this video I show how to connect a basic circuit with just a PIR sensor, a transistor and a couple of other components to produce a reliable and power saving motion called lighting circuit - ideal for building a night light or for having a string of LEDs switch on when you are present.
PIR sensors can used with Arduino or any other microcontroller (eg Raspberry Pi) to make more sophisticated controllers and I'll cover how to do this in a second PIR video.
