particular importance due to the growing need for people
to feel secure in their homes and mitigate crime risk [3].
The advent of cutting-edge technologies like the Internet
of Things (IoT), compact microcontrollers, and affordable
sensors and actuators has opened up new possibilities for
implementing safety and security features in intelligent homes.
These systems are crucial in monitoring indoor environments,
providing homeowners with real-time updates and alerts when
potentially harmful situations arise, even when they are away
from home. The primary goal is to analyze data collected from
sensors in the surrounding environment and trigger appropri-
ate actions through actuators to address or prevent potential
threats. Many researchers are working to create custom-based
security solutions that are cheap for everyone in order to solve
this issue.
In this situation, we have intended to develop such a security
system that can make the human life easier and feel secure
when they are not present in the home. Owing to increase
the quick movement of pupils, creating them needs a security
technique. This has the properties of cell phone technology in
words of receiving Information simply.

Security concerns have become increasingly prominent in
our daily lives, particularly when we are away from home
[4]. To address these issues, modern technology has been har-
nessed to develop solutions for safeguarding us from various
hazards. The field of security research has seen significant
progress, as evidenced by recent studies in this area.
Baballe et al. [5] designed an IoT security alarm system
employing an Arduino microcontroller and PIR sensor. The
system detects intruders, relaying notifications through an
LCD display and GSM modem. Albak et al. [6] created a
remote security system using Arduino and mobile phones,
utilizing an infrared sensor for motion detection and sending
alerts to property owners. Sarhan et al. [7] established an
Arduino-based smart home warning system that detects events
like fire, gas leaks, and break-ins, notifying users via SMS and
email. Beside this, Rakib et al. [8] explored GSM technology
for remote control of home appliances and security systems,
offering feedback through calls and a mobile app. Nwe et
al. [9] developed an IoT-based smart security and home au-
tomation system, combining Bluetooth and home automation
to create a safe environment. In addition, Oyekola et al. [10]
created a home security system using IoT and smartphones,
integrating GSM technology, ultrasonic sensors, PIR sensors,
and gas detectors for wireless remote security. Abdullah et al.
[11] emphasized the IoT’s role in intelligent home systems and
city security, enhancing privacy and security through various
platforms and communication protocols. Elimarteena et al.
[12] highlights the growing significance of security systems in
homes, businesses, and industries. A financially robust home
security framework is crucial for increased security levels.
A system detects unauthorized entry using PIR sensors and
a siren, providing accurate data to a cloud server. Shankar
et al. [13] explored using advanced technologies, particularly
Arduino, to create a security system for protecting belongings
from theft. The current system uses a manual lock and key
mechanism, lacking notification. The proposed method uses
an Arduino, mobile phone, and motion-detecting camera to
detect and notify the owner of theft. A PIR motion sensor
detects motion and triggers the camera to capture images.
Signals are sent to the Arduino, which initiates a call when
belongings are stolen. Gupta et al. [14] focused on creating
an automated security system for home monitoring, detecting
intruders, gas leakage, and fire. It uses sensors and a GSM
module to transmit information to the owner’s mobile phone.
The Arduino Uno processor is the central processing unit,
interfacing with sensors and appliances. GSM technology
sends warning messages via SMS to the owner’s mobile phone,
with an LCD displaying the information. The system’s global
coverage allows remote alerting and action.

We have conscious about our security, Like as health and
asset of our daily life. Security has an important role in our
daily life. We have lived in such a modern society where
technology has discovered many tools in our daily life. In such
a situation we have developed a system of the security module,
it can diminish the misconduct ratio in the world particularly
the crime of stealing at home. In the meaning of the up-to-
date life every day we need to go away from the home for the
various reason of our life. We have designed such a device
that basically concentrates on giving security when the user is
out of the home.
The system includes PIR sensors to sense an impediment,
GSM, Module for communicating with GSM Phone. PIR
sensor discovers motion by recognizing the distinction in
infrared or radiant heat points emitted by nearby objects. The
outcome of the PIR sensor moves extremely when it senses
any motion. The variety of a distinctive PIR sensor is about 6
meters or near 30 feet. For the 100 percent accuracy of PIR
sensor, it should be required a preparation time from 20 to
60 seconds. It is needed for the reason that PIR sensor has
a perching time through which it regulates its sensor along
with the surroundings besides soothes the infrared detector.
Through this time, there must be marginally to no movement
in front of the sensor. The outcome of the PIR sensor cannot be
trustworthy if the sensor is not given much time to calibrate. At
the time of sensing any motion by PIR sensor, the outcome of
the sensor is great. This article mainly concentrates on giving
security when the user is left home.
Our project main facility that can send messages fastly,
appropriately and at a minimum price at any place within
the GSM network. As the Mobile phone is the latest and the
most usable technology in this day with SMS service will
be extremely valuable when used to incorporate the security
frameworks or systems, where the news directs by a security
frameworks also the news got by the client’s cell phone
in the format of SMS. Upon this, an incorporated security
framework is made to have the capacity to direct information
except applying a PC (Personal Computer), that helps control
the condition of the house fastly as well as inexpensively
[15]. The dialect of C programming is connected to make
this framework, the program was utilized to manufacture a
security framework that runs naturally, which can make two-
path interaction by client cell phone at the time of security
break in the home [16]. The two-way connection employed to
kill the ringer in the wake of working when a security break
happens. Incorporated into configuration used to create simply
expandable for adding more sensors to the primary framework
Arduino Uno open-source microcontroller podium.
Our system is instigated by the Arduino. Arduino is inter-
facing with the GSM module at that point associates through
the GSM module by means of serial transmission to create a
call to the pre-modified versatile (cell phone) number. It is a
significant idea to be noticed around PIR that the result will be
incredible when it detects movement. The result of PIR sensor
more often than not endeavors low now and again, if there is a
movement which could betray the microcontroller into seeing
that there is no movement. Our programming unit of Arduino
is controlled by avoiding the low output signals. Which have a
smaller interval than a predefined time. This project has been
completed by adopting that the movement before PIR sensor
is existing constantly.
