IoT Enabled RO Water Filter Indicator

The Internet of Things (IoT)-based technologies are increasingly becoming the primary driver behind unprecedented global change. Wi-Fi air conditioners, smart TVs, and Bluetooth smart light bulbs are just the beginning of their infiltration into our living spaces. In this paper, we detail the design and implementation of the prototype i-Water system, an IoT-based water purification system for residential use. As a result of the integrated monitoring tools, the owner of a RO water purifier can always know how their devices are faring. To ensure that the water is constantly purified, each purifier is hardwired into the system. The owner of the RO system can inspect it whenever necessary.
