| Summary: | The problem of water wastage is a classic problem that exists in modern society
today. Easy access to clean water often causes people to forget that the use of
clean water needs to be done responsibly and as efficiently as possible. We also
encounter this problem in the ITB campus area. Based on a survey that we have
conducted on public toilets in several buildings on the ITB campus, we have
encountered problems with excessive water use and frequently encountered
unattended open taps. Where this is a form of waste of clean water in the ITB
campus environment. Based on this, we designed a "Water Use Monitoring
System for Public Toilets in ITB Campus based on the Internet of Things". This
system is divided into three major subsystems, namely the Payment System, the
Smart Water Sink System, and the User Interface System. In the development of
this monitoring system, the authors take part in the work of the verification and
water flow control subsystems of the Smart Water Sink System, which its design
and implementation will be discussed in this paper. The test results on this system
have successfully met specifications such as working with a DC voltage input of
12V, being able to detect up to 3.5 cm in front of the hand sensor, being able to
read user verification input correctly and consistently, having a processing speed
of reading verification input <5 seconds, being able to limit tap usage per session
for 15 seconds, able to detect ticket usage limits, able to communicate data with
the server, able to measure water usage with an accuracy below 10%, and has an
indicator light as a user interface. |
