Once motion is detected, the sensor sends a HIGH signal to the microcontroller, which can be used to trigger a response such as turning on an LED or activating an alarm. In this experiment, the PIR ...

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 ...

Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the ...

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 ...

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 ...
