The smart home and management system in this study are powered by D.C. batteries. It can operate for two to three days on a fully charged battery before running low. The project title and the maximum temperature are shown on the LCD when the system is powered on. It will also demonstrate to you that the house is empty. The quantity of persons you choose to enter the house is up to you. When the maximum is set to 12, the door won't open again until someone hits the escape button and leaves the house before someone else can enter. There is a fan in the house that is used to cool the temperature of the house if it is hot, and you can choose when you want the fan to turn on automatically by selecting the maximum temperature. If you choose the maximum temperature to be 30 °C, the fan will not operate until that temperature is reached. And if everyone leaves the house, both the fan and light will automatically switch off since no one is inside the house. There is a light in front of the house for security reasons. If it is dark at night, it will automatically turn on. This light is controlled by the second light-dependent resistor outside the house. If the LDR senses the presence of light, the bulb outside the house will switch off during the day, and if it senses the presence of darkness, that is, at night, it will turn on itself for security purposes. The first LDR is inside the house. If any person enters the house, it will turn on the light in the house. The light will not go off until everyone leaves the house. There is a smoke detector sensor to sense the presence of fire in the house; if there is a fire outbreak, the GSM Module and ESP32 that are used in the research will help send a message to the houseowner. These messages will both be sent as SMS and through a smart phone using a Wi-Fi connection. Most of the research done nowadays doesn’t have both an IoT connection and a GSM module. Also, a motion detection sensor is used to detect an intrusion. If an intruder tries to enter the house or approach the house by the time everyone is asleep, it will send an SMS to the houseowner that they are motion-detected.
