Smart mineral water bottle using Internet of Things

The objective of this work is to develop an IoT bottle of mineral water. The system will periodically check your water level, when it is empty, it will automatically fill it from another common carboy that is at ground level, thus avoiding the repetitive effort of changing carboys. This system was implemented to serve the elderly, people with special needs and the general public, through a low-cost microcontroller, NodeMCU ESP8266, using a horizontal float-type water level sensor, a mini diaphragm water pump and a relay. In addition, the platform allows the monitoring and control of metrics through an MQTT application for Android
