An Implementation for Smart Home System based on Internet of Things

Abstract

The Internet of Things has a critical role in smart home systems techniques. A smart home system provides a major change in the life of humans that gives home appliances intelligent operation. These changes encouraged us to create a solution for controlling certain home appliances, such as doors and lights. This system is used to monitor the status of the door and windows, temperature, humidity, and measuring distance by using various sensors such as IR, DHT22, and ultrasonic sensors. In the main parts of these applications, NodeMCU ESP8266, relay module, and Arduino Uno used. The system presented in this workable to monitor and control home appliances from any corner of the world at any time and efficiently utilize by properly controlling the appliances. Ubidots IoT platform and Blynk application were used to check and read data from sensor modules placed in the home and, also to control home appliances by turning on/off relay switches such as doors and lights. The work also focused on protecting user's data by using the AES method to ensure that a system encrypts and encodes Wi-Fi information before sending it to a destination. Eventually, the system decrypts and decodes the data to restore the original data.
