Statement of Purpose
The project is to create an umbrella that captures rainwater and fills up your water bottle as you are walking somewhere. This object is very beneficial in rural areas or areas where there is limited water supply from taps.
Background Research
There are types of umbrellas that have an inverted top that forms a cone to help contain water on the inside of the umbrella when it is closed. However, there are not many designs that utilize the inverted shape to capture rainwater. We will be taking the design a step further and utilizing it in a different manner to help with water conservation.
Block Diagram / Flow Chart
System Overview
Battery block describes the role of the battery in powering this entire Arduino. Without the battery the Arduino and the remaining sensors would not function.
The Arduino is the center block of the entire project. Based on the input information given by the sensors, the code onboard the Arduino makes a decision on whether or not to open the flow of water to the filters and then to the water bottle.
The On/Off button will turn on the motor and change the setting of the umbrella so it can filter water.
If the laser from the emitter and the receiver is distorted, that means there is water, so then the information gathered from the sensor will go to the Arduino and the respective code will be executed closing the hatch to stop more water from entering.

Possible Challenges
Assembly under the umbrella's size limitation will pose a challenge for us to solve using various techniques. Building a water proof element underneath the umbrella while some part of the element has to come in contact with the water. Trying to keep the weight and balance of the umbrella as light as possible is a challenge as with all of the electronic elements, the weight and balance of the umbrella will shift greatly.
