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 ...

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!

PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors ...

Components used in this project: 1x Arduino 101 3x Jumper wire 1x PIR sensor 1x LED light 1x USB cable Background: Arduino 101 is a microcontroller which can take in inputs and produce an output. 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 ...

Security Alarm This article is about making an intruder alarm using Arduino and PIR sensor. When the PIR sensor will detect an intruder, it will send a signal to Arduino and the Arduino will sound an ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor.

Motion sensor alarms are readily available in the market, but these are expensive. Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security ...
