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 ...

Arduino Uno: Drag and drop the Arduino Uno R3 board from the components panel into your workspace. PIR Sensor: Search for the PIR sensor in the components panel and drag it into the workspace. LED ...

To detect motion using a PIR sensor connected to an Arduino and trigger an LED (using the built-in LED) when motion is sensed. Passive Infrared (PIR) sensors are electronic devices that detect motion ...
