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: ...

A number of technologies are available to design automatic door openers like PIR sensors, Radar sensors, Laser sensors, Infrared sensors, etc. In this arduino based project, we have tried to replicate ...

PIR sensors are commonly used in security alarms and automatic lighting applications. The output of PIR motion detection sensor can be connected directly to one of the Arduino (or any microcontroller) ...

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 this video tutorial, we will learn how a PIR Sensor works and how to use it with the Arduino Development Board for detecting motion.

RCWL 0516 Module The RCWL-0516 Microwave Radar Sensor module has been designed as an alternative to the common PIR motion sensors widely used in burglar alarms and security lights. Like the PIR Sensor ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad.
