Smart Home Automation System Using Cloud Computing Based Enhancement Security and Environment

In this paper, a smart home automation system is proposed can detect any leakage of gases, smoke, and fires with a prior warning sent via the Telegram application to the owner. When any danger is detected, the ventilation fan will work immediately to reduce the amounts of gases. Another mechanism that achieves a suitable climate for the home and reduces energy consumption is by connecting heating and cooling devices to the motion sensor. A two-threshold value has been added to avoid the machines turning on and off continuously when the temperature fluctuates at a certain value, as will be clarified in this paper. Regarding the security aspect of the house, a sensor has been placed inside the house on doors and windows to detect any movement, and sends instant photos of the place to the cloud and alerts via Telegram at the same time. These sensors are also connected to a microcontroller, which transmits data and values that will be processed, stored, and displayed in fog computing via a user interface, and then over Wi-Fi to the cloud. The time of sending data from the sensors to the graphical user interface (GUI) is instantaneous, with one second between reading and another, while images are sent from the internal camera with a time of 30 milliseconds, which is the processing time only. The system has been implemented in practice with good results in terms of reading accuracy and response time.
