In this blog, we will learn about how to interface a Passive Infrared sensor (PIR Sensor) or motion sensor with an Arduino. We will also learn about how this sensor works and different parts of it. So ...

PIR : A PIR (Passive Infrared) sensor is an electronic device that detects the presence of a person or an animal by measuring the infrared radiation emitted by their body heat. It is commonly used in ...

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 ...

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 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 ...

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

In India, nearly 20 percent of the electricity is lost due to technical and commercial reasons. Three billion units of power are wasted every year. The Automation of lighting system with the usage of ...
