Arduino with PIR Motion Sensor- that can detect movement. simple circuit with an Arduino and PIR motion sensor that can detect movement. An LED will light up when movement is detected.

Smart-door-using-Arduino-and-PIR-Sensor- An Automatic Door Opener System is a project based on PIR Sensor and Arduino, which automatically opens and closes the door by detecting a person or object.

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

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 challenges such ...

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 salt based ...

The complete circuit diagram for Arduino Based Decorative Christmas Tree is given above. It is pretty simple as we only need to connect a PIR sensor, JQ6500 voice module, and Neo-Pixel LED Strip.

Arduino based Fire Alarm – Circuit and Working Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...

The actual circuit is just a piece of perfboard, a large, old relay from Sparkfun, and a PIR sensor [Greg] picked up last year.
