GSM Based Home Security System With SMS Alert | Simulation
————————-
📌Introduction
————————-
This project has GSM technology and anti-theft system using PIR motion detection. Whenever Motion is detected it sends the SMS on predefined mobile number. We have connected PIR Motion sensor with this project.
GSM based home security system with SMS alert, it uses PIR Motion Sensor, GSM Modem and 16×2 LCD is used to display system status, It Sends SMS through GSM modem that is attached to Serial Rxd and Txd Pins when motion is detected from PIR sensor, Set your mobile number inside the code in SendSMS subroutine.

📌 Project Futures
————————-
1. Sends Theft Alert SMS to Given number.
2. Displays status of system on LCD.
3. Motion Detection
4. Real Time Tracking System

📌 Component Selection

1. PIR Sensor :
PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don’t wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, “Passive Infrared”, “Pyroelectric”, or “IR motion” sensors.
PIRs are basically made of a pyroelectric sensor (which you can see below as the round metal can with a rectangular crystal in the center), which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted. The sensor in a motion detector is actually split in two halves. The reason for that is that we are looking to detect motion (change) not average IR levels. The two halves are wired up so that they cancel each other out. If one half sees more or less IR radiation than the other, the output will swing high or low.
2. GSM :
GSM stands for Global System for Mobile Communication. It is a digital cellular technology used for transmitting mobile voice and data services. Important facts about the GSM are given below −
1.The concept of GSM emerged from a cell-based mobile radio system at Bell Laboratories in the early 1970s.
2. GSM is the most widely accepted standard in telecommunications and it is implemented globally.
3. GSM is a circuit-switched system that divides each 200 kHz channel into eight 25 kHz time-slots. GSM operates on the mobile communication bands 900 MHz and 1800 MHz in most parts of the world. In the US, GSM operates in the bands 850 MHz and 1900 MHz
3. Arduino:
Arduino is a prototype platform based on an easy-to-use hardware and software. It consists of a circuit board, which can be programmed and a ready-made software called Arduino IDE.The key features are ,
1.Arduino boards are able to read analog or digital input signals from different sensors and turn it into an output such as activating a motor, turning LED on/off, connect to the cloud and many other actions
2.You can control your board functions by sending a set of instructions to the microcontroller on the board via Arduino IDE
3.Arduino does not need an extra piece of hardware in order to load a new code onto the board. You can simply use a USB cable.
4. Additionally, the Arduino IDE uses a simplified version of C++
