A smart bathtub system is a new type of accommodation with modern and intelligent facilities of a smart home automation system. It is equipped with a multi-sensor system that will be used to recognize human activities within the bathtub to make it secure, save energy and water. This system design with an interaction design process aims to enlarge product usability; was applied during the development tools. In this smart bathtub system, sensors have been installed with a variety of appliances, the presence sensor can be used to monitor human occupations, also the water level sensor to read the water level in the bathtub. Another part is the auto water faucet line that is supposed to flow water in the bathtub. The presence sensors detect a presence in the bathtub that would automatically initiate the automatic process. First, it detects the presence, and it checks the human activity in the bathtub while the system is active. If the object is present in the bathtub then the automation system will work otherwise not, like water level sensors and water faucet lines would not work if a person’s presence is not in the bathtub. Water level sensors send reading data to the microcontroller, if the water is empty water faucet will turn on, and water flows in the tub. The results demonstrate that the proposed method can detect the conditions of the bathtub presence activity and water level detect effectively with the best-experimented results showed 100% that the water line could be open if presence in the bathtub.
