Abstract

Nowadays, almost all communication using the internet, but is not all, now object also can communicating each other, this concept is calls the Internet of Things (IoT). Things in IoT can be everything that we use every day. In this project, the thing is a water container, or in Indonesia, it called ”bak mandi. Why water container? Because, after we use water in the water container usually the level of the water container is reduced and we must fill it up for other people that use the water container. Generally, in the process of filling the water container, we forgot to close the valve or pump so water is overflowing and the water is wasted. That is why we propose to use the Internet of Things concept that can solve the problem. Our approach utilizes a controller of ESP8266 that can provide monitoring level of the water container. That controller will open and close the pump or valve automatically so that the water is not overflowing and wasted. We use an ultrasonic sensor to sense the level of the water. We utilize the Blynk IoT service incorporated with PHP web programming in providing water level monitoring and control. We have tested the system on a 64 cm water container. The system has an error of 2 cm in controlling the water level.
