Incidents like thefts, fire, and LPG gas leakage are very common these days. What is uncommon, is people’s awareness of different systems like smoke detectors, gas leakage detectors, etc. Installing all these different detectors in order to keep the house secure is also something that is difficult to maintain. Here, we have designed an integrated home security system that would help people secure their houses from such incidents. IOT based Home security system using the Arduino project is designed to help an individual secure his/her house from theft, fire, and LPG gas leakage – all in one.

Description of the project
This project uses four different sensors, from which data is sent over a website through IOT. The Internet of Things (IoT) is basically, the network of ‘things’ by which physical things can exchange data with the help of sensors, electronics, software, and connectivity. These systems do not require any human interaction.
A detailed description of IOT based Home security system
IOT and Arduino Based Home Security System uses four Sensors, namely, Temperature, Smoke, LPG, and IR sensors. Data from these sensors is then sent to the Arduino, which has an inbuilt signal converter. Arduino then sends data over to the Wi-Fi module – ESP8266. ESP8266 is a chip used for connecting micro-controllers to the Wi-Fi network and making TCP/IP connections and sending data. Data, which is sensed by these sensors, is then sent to the IOT.
To elaborate on theft detection, we have connected a password module by which a user can enter the password. The door would open only if the password entered is correct. The IR sensor needs to be installed on the door, which is, by default activated. If an individual enters the correct password, the IR sensor is deactivated for 10 seconds and the buzzer won’t turn ON. If somebody tries to enter the house without entering the password, i.e. by damaging the lock or so, as soon as the person passes the IR sensor, the buzzer would be turned ON.
The buzzer would be turned ON even if a wrong password is entered consecutively 3 times. To demonstrate the door, we used a DC motor. The buzzer will turn ON even when it detects smoke from incense sticks as well as a candle flame.
Data sent over the cloud using IOT:
Temperature and Smoke sensors are used for fire detection. The signal will be sent to the microcontroller as soon as the fire is detected. That will then send appropriate data to the LCD and the Wi-Fi module.
Data is then sent to the website using the IOT module. Similarly, the LPG sensor is used for LPG gas leakage detection. The Prerequisite for this project is that the Wi-Fi module should be connected to a Wi-Fi zone or a hotspot. This project is also implemented without the IOT module. We have used a GSM module In place of the IOT module. GSM modem triggers the SMS.

Applications of the Arduino and IOT based Home Security System project
- Security being the main intent of the project, the most important application of this system is any domestic security. By using this project, a person will be intimidated about any incident likely to be caused by fire, theft, or LPG gas – REMOTELY.
- This project can be used in Restaurants, Industries, Manufacturing units, Banks, etc.
Advantages & Future Development
- The main advantage of this system is that it is fully automated. Once installed, it does not require any kind of human interaction. Also, it is very cost-effective.
- IOT and Arduino based Home Security System can be enhanced to identify fingerprints as opposed to a password using a keypad.
- Additionally, we can have a voice announcement system. It would send out vocal instructions regarding any of the four hazardous conditions detected by Smoke, Temperature, IR, and LPG gas sensors.
