An Arduino based Automated Faucet with Hand Dryer and Voice Announcement

Abstract

This paper is presented about automatic faucet system called SOWAIER to facilitate the people by avoiding the interaction between system and person. This system is developed to keep the people safe from infections and minimize the usage of water during hand washing. The ultrasonic sensors and IR sensors to make voice announcement and detect the people. There are 3 IR sensors used in this system for delivering soap water, clean water and hand dryer. Initially, relay module with integrated with solenoid valve gets signals from microcontroller to actuate submersible pump for delivering soap water for 20 secs. Then, clean water is delivered for 15 secs and finally hand dryer system is actuated for 10 secs. The hand dryer system uses air blower. The simulation study is carried out by using ANSYS software to evaluate the temperature and velocity magnitude at the outlet of hand dryer system. The simulation results suggested that the sufficient air flow rate is achieved at outlet of hand dryer system with appropriate temperature. Moreover, this study also dealt with water scarcity on the earth. Hence, this system is made to cut off the water flow to avoid the accidental flooding even the user leaves it in the running conditions.
