# Automatic Water Bottle Filler

# Problem
In normal liquid dispensing and water bottle filling systems, the process requires the user’s attention and constant manual activation of the device. This may require the holding of a button, the action of pushing the bottle against a sensor for a specific amount of time, or holding the bottle in front of a sensor until it is full. If the user gets distracted or is unable to provide that attention (blindness or lack of motor function), liquid may spill or the bottle may not be filled enough.
# Solution
Our goal with this project is to make an automatic water bottle filling station. Our device senses when a water bottle is placed underneath it, begins filling the bottle with water once a start button is pressed, determines when the bottle is full and shuts off automatically. After placing the bottle on a platform and pressing a button, the user can walk away knowing their bottle will be filled accurately.
# Solution Components
## Sensing Component
This subsystem utilizes multiple sensors including an ultrasonic sensor to measure the water level and a light-based sensor to determine the height of the bottle.
## Control
This subsystem connects the sensors to the water system. It receives data from the sensors, compares the water level height to the height of the water bottle, then decides to either begin, continue, or stop dispensing water.
## Display/Interface System
An LCD display will show instructions for the user and will display simple messages. A few push buttons will be included for manual filling and selection of desired amount of liquid (ex. Half bottle, full bottle)
## Water System
This subsystem utilizes a water tank attached to a pump and tubing, which transport water to the dispenser.
# Criterion for Success
The device…
- detects a water bottle and accurately measures the height
- monitors the water level in the bottle
- stops filling when a desired water level is reached
If there is no bottle/ the bottle is removed, the device stops filling water.
