Step 9: Using a breadboard and the Arduino Uno, build the circuit specified by the Fritzing diagram, with the relay connected to digital pin 8 and the PIR sensor connected to digital pin 13. Step 10: ...

The Arduino continuously monitors the state of the signal pin. If the signal pin goes HIGH, it means the sensor has detected motion, and the Arduino is programmed to turn ON the built-in LED on pin 13 ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

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 ...

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 ...

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad. Hi there! I hope you are doing great. Today I am sharing the Proteus ...
