The problem

  • Approximately 300,000 people are living with multiple sclerosis in the US [1]
  • Approximately 500,000 people that are currently living have been diagnosed at

some point in their life with lung cancer in the US [2]

  • These diseases cause breathing ailments that can dictate people's lives

User’s requirements

  • Easy to use

○ Sample user interface ○ The external water tank shall be easily refillable

  • Keep the user cool underneath

○ The device shall shade an area with lowered temperature to 65-70 °F. ○ The device shall provide humidified air within 30% - 60% relative humidity for the user.

  • Implement Solar panels

○ Within a safe transmission voltage.

  • Light weight

○ Around 1.5 lb.

The solution

  • An umbrella that has a built in humidifier
  • A water tank that will store the water for the user
  • A cooling system that could incorporate a fan to use evaporative cooling
  • A microcontroller that will be able to automatically regulate humidity
  • Solar panels with a back up battery to power the umbrella

Cooling System

Evaporative Cooling[6]:

  • Heat from skin evaporates the sweat lowering the average kinetic energy on skin
  • Lower kinetic energy reduces the temperature
  • Effectiveness can be increased using a fan

Swamp Cooler:

  • Reduces the temperature by increasing the relative humidity
  • Typical used in high temperature and low humidity
  • Operation:

○ Evaporative pad is used as a median to evaporate the water ○ Water distribution keeps evaporative pad damp ○ Fan pulls in hot air and exhaust cooler air into environment

Reflective Material[7]:

  • Preventing heat absorption from the canopy of the umbrella
  • Aluminum or a space blanket is able to reflect UV-rays and prevent heat absorption

due to its reflective index 8

Cooling System

Cooling Projection: [7 ]

  • Psychrometric chart: a visual representation of how relative humidity affects the

temperature

  • Based on the wet and dry bulb, temperature may be adjusted by increasing the

relative humidity

  • Maximum usage Temperature:

○ 96 ℉ at 50% relative humidity 9

Data Receiving and System Control

Raspberry Pi Zero [18]

  • Designed to be user friendly with a vast amount
  • f tutorials online
  • Prebuilt onto a PCB, only soldering required for

components

MSP430 [19]

  • Lower power consumption with multiple low

power modes

  • Cheaper but requires a PCB to be built
  • Low amount of RAM could become an issue

Humidity and Temperature Detection

AM2302 [20]

  • A bigger version of the DHT22 that has an external casing
  • Already has the bridge resistor built into the sensor

DHT22 [20]

  • Bigger and more precise version of the DHT11
  • Is usable within more ranges of temperature and humidity

than the DHT11

DHT11 [21]

  • Least precise sensor but also costs the least
  • Will use less power while active but consumes slight more

while idle
