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 ...

Explore simplicity and innovation in our DIY Motion Sensor Light project. Learn to create an efficient LED setup using a PIR sensor, relay, and basic components – no microcontrollers required. Elevate ...

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!

Now that the relay is complete, place the top of the enclosure back on and secure it with the screws it comes with. Step 9: Using a breadboard and the Arduino Uno, build the circuit specified by the ...

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

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

This is a simple update to Mr. Hareendran’s PIR Sensor Security Light circuit. It has a shortcoming limits the relay voltage to approximately 3.3V. While this may function with some 5V relays, it will ...

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 ...
