The topmost part of the PIR sensor consists of a lens with concentric grooves carved into the plastic. These are called Fresnel lens. The contours on this plastic helps in gathering parallel light ...

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. You might have seen Automatic Door Opener ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

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 ...

You must have seen automatic door openers in shopping malls and other commercial buildings. They open the door when someone comes near the entrance and close it after sometime. A number of ...

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 ...
