The automatic urinal flushing system has been developed in the market for a long time. However, none of them is smart. No information is collected from the traditional automatic urinal flushing system. No one knows how many times it has been used in a day. No operational status is informed unless users have to be present right in front of them. In this paper, a smart automatic urinal flushing system is proposed. It is designed and implemented to provide the usage information to a caretaker. With the smart system, a caretaker will be able to use the usage information to estimate or to analyze the number of users in each day, or each week. It is also possible to know which urinal has been used the most, so it should be taken care more than the other ones. The proposed system is tested under different scenarios. The results show that in a normal circumstance, the propose system is working as expected.
