Smart hydration system

A system for a smart cap for a liquid container, the system comprising:

• a cap comprising a housing, a battery, a microcontroller with a wireless transceiver, a straw coupling, a straw connected to the straw coupling, and a flowmeter, the flowmeter comprising a magnetic rotor with a Hall effect sensor in communication with the microcontroller, wherein the magnetic rotor sits within a liquid flow path of the straw and rotates when liquid passes across the magnetic rotor wherein the Hall effect sensor is located on a same plane as the magnetic rotor and is positioned outside of the liquid flow path;
• a mobile device comprising a mobile application;
• and
• a liquid container configured to contain a liquid, wherein the cap is attached to the liquid container;
• wherein the Hall effect sensor detects the magnetic field oscillations created by a spinning rotor allowing the microcontroller to compute a rotation count and a speed (revolutions/time) which can be used to calculate a volume of liquid that has passed through the flowmeter;
• wherein the wireless transceiver of the microcontroller transmits the volume of liquid that has passed through the flowmeter to the mobile application;
• wherein the mobile application is configured to utilize the volume of liquid for at least one of daily goal tracking, a performance optimization or a drink log.
