The motion sensor switch circuit can automatically turn on a water sprinkler but you can easily use it as a motion sensor light switch or motion activated alarm too. Before beginning the construction ...

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 ...

If you are interested in building more project using PIR sensor you can check out the tutorial on how to use PIR sensor with Arduino. For this homemade motion sensor light project though we wanted to ...

Arduino Motion Sensor for Controlling Electrical Devices activates or deactivates electrical devices in response to human movement.

There's really not much to the motion sensor. The sensor shoots out an invisible light field that spans 100 degrees horizontally and 100 degrees vertically. Its blind spot is 180-degrees to its sides.

Elgato's Eve lineup of smart home devices is one of the largest contributors to the HomeKit ecosystem, with a variety of sensors and switches for inside and out, including five more products ...
