The PIR sensor successfully detected motion and triggered the Arduino to turn ON the built-in LED. The LED remained OFF when no motion was present, confirming correct circuit and code functionality.

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

You must have seen automatic door openers in shopping malls and other commercial buildings. They open the door when someone comes near the entrance and close it after sometime. A number of ...

Abstract: In this paper, the Arduino based Intruder Detection System employing Rochelle Salt and Pyro-electric or Passive infrared (PIR) Sensor has been proposed. The proposed system employs Rochelle ...

Abstract: In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present ...

Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...
