Arduino PIN-Protected Alarm System with Motion Detection An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion ...

Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security purposes.

The developed system makes use of an embedded system (comprises an open hardware microcontroller and a gsm modem) based on Global System for Mobile communication (GSM) technology. The designed & ...

In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.

In this project, we would be constructing a smart home security system that can notify us when someone breaks into our shop or home.

The Arduino Security System is a technology that uses PIR (Passive Infrared Sensor) sensors to detect such motions. This device has been created for home security systems. It uses Arduino Uno as a ...

In this project we are going to build a Dog Barking Security Alarm using Arduino Nano, PIR Motion Sensor, and Dog Barking Sound Module.

This project aims to help the public in protecting and avoiding criminal cases that are likely to occur in their neighbourhood. Such cases occur when the occupants are not at home or possibly even ...
