Hydrator
The water bottle that uses a pressure sensor to indicate how much liquid you have consumed.
This project uses an e-textile pressure sensor consisting of velostat and conductive fabric.
Process
Visual feedback
In order to understand the values without the serial monitor, I attached a strip of addressable LEDs.
The feedback indicates when it is time to drink water, if the user drank water "long enough" (aka the bottle in the air and not applying pressure to the sensor), and if enough water was consumed to move into the "section".
