Project Overview

Description:

The Smart Shower allows users to control their everyday showers at the sound of their voice or the tip of their fingers. By connecting pre-existing showers to sophisticated smart home technology, homeowners can enjoy a showering experience like none other.

Issues with Common Showers:

  • Shower handle position requires manual adjustment
  • Shower water temperature varies
  • “Cold Shock” when shower starts
  • No current methods to add timers or limit shower duration
  • Water is wasted waiting for shower to get to right temperature

Capabilities of Smart Shower :

  • Turns shower on and off
  • Controls and maintains temperature
  • Primes shower to correct temperature
  • Supports touchscreen and smart-home assistants
  • Supports timed showers
  • Reports water usage
Interface on tablet

Methods

Shower into tub with sensors
  1. Smart Shower Head: Shower head with integrated LEDs, flow sensor, temperature sensor, and shutoff valve. (Patent pending)
  2. Shower Valve Motor: Servo that controls the shower valve to turn the water off/on and maintain the desired temperature
  3. Smart Shower CPU: Controls the motor and LEDs and receives the sensor data from Smart Shower Head. Communicates with Touchscreen and Smart Assistant.
  4. Touchscreen: GUI to turn on/off the shower, set the water temperature, display current water temperature, set timer, prime the shower, and display water usage.
  5. Rock: To keep your dreams from floating away.

Conclusion

Results

The Smart Shower system works as expected. More specifically, the system we designed is able to:

  • Measure the shower temperature within 2° F
  • Adjust and maintain the shower temperature by turning the shower valve
  • Interface with the user through Alexa and a touchscreen
  • Measure water consumption
  • Prime the shower to a set temperature

Future Work:

  • Integrate with other smart assistants such as Google Home or Siri
  • Allow for additional shower types other than rotational valve
  • Design encasements for shower head and motor circuitry
