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 ...

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 ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Motion detection is an essential part of security systems and PIR sensor is one of the most commonly used sensor for trigging the alarms when motion is detected. This sensor can detect human/animal ...

This project is an example of a PIR motion sensor for the Philips Hue bridge. The sensor can be registered at the Hue bridge as an IP sensor to control lights connected to the hue bridge. The sensor ...

WeMos D1 mini Module in the online interface now from reading the switch/button sensor type guide it says for a motion detectors / PIR use switch 9. But there is no switch 9 it only goes up to switch4 ...
