Teenager designs smart water bottle

03 Oct 2021

Sebastian in Uruguay invented a water bottle that encourages people to stay hydrated

The ‘smart water bottle’ uses BBC micro:bits for two functions:

  • it measures the intensity of the sunlight and reminds you to shelter and stay hydrated
  • it checks the water level in your bottle and reminds you to take a sip

The do your :bit judges felt that Sebastian’s device stood out as a well thought through creative idea. Sebastian won the 15 to 18-year-old category in Latin America. He aimed to solve a problem related to Global Goal 3 Good health & well-being.

The smart water bottle in action

The do your :bit challenge is an annual competition which sets young people the challenge to innovate and design solutions relevant to the impacts of the Global Goals that are meaningful to them.

Hydration is essential for everything, the so-called climate change that we are fighting against today provides us with very high temperatures that we must take care of, specifically in my community Uruguay as we are below the hole in the ozone layer.
