The rising area of Internet of Things (IoT) intends to unify sensors data all over the world through the web. In this context, new technologies emerge to bring integration between society and those data. This paper proposes a low-cost method to measure water tank level and send it to the Internet for remote monitoring. A search was made on patents and papers index databases to verify similar technologies. Using a cheap microcontroller and wires as switches, the water level was measured, this data was uploaded on the cloud through MQTT protocol, in JSON format, and even a relay for a water pump was actuated. Further, some other ways to improve this work and how it differs from existent technologies were discussed.
