In the microcontroller era today, Arduino is more than just a tool ... is used to measure the light level. The alarm system is triggered when a “Logic High (H)” level signal is detected at its sensor ...

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 alarm. This ...

They can also deter burglars from deciding to enter a home. So in this tutorial, we are going to build a Dog Barking Security Alarm using Arduino Nano, PIR Motion Sensor, and Dog Barking Sound Module.

This project uses an Arduino Uno to build a burglar detection alarm system with a PIR sensor. The system triggers an alarm when motion is detected, signaling with an LED and a piezo buzzer. This code ...

This project implements a simple burglar alarm system using a Passive Infrared (PIR) sensor and an Arduino Uno. When motion is detected by the PIR sensor, the system activates an LED and a buzzer to ...

Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security purposes. Typically, for outdoor monitoring, motion sensor alarm consists of a PIR ...

So this was the whole procedure to make an intruder alarm bu integrating a PIR motion sensor and a GSM module with the Arduino Uno microcontroller board. Now you can follow the above steps and enjoy ...

Do you know how to design this circuit and how it works? Are you interested to know about its various applications in real life? Then read the post PIR Sensor based Security Alarm.

We previously used PIR sensor to build various kind of alarms and security systems ... follow the link and also learn how PIR sensor can be used with with Arduino, Raspberry Pi and other ...
