Introduction


In your hot college dorms, there seems to be lack sufficient air conditioning. As a result, a lot of college students have a fan that they use to regulate the temperature. Although, the air temperature in college dorms is often fluctuating. Enter The Smart Fan. The purpose of our project is to create a fan that can regulate the room's air itself. This fan will be able to detect the temperature of the room, and will either turn on or off accordingly. Not only that, but the fan will only turn on if someone is in the room. Thus, if someone turns the lights on and the room is above a certain temperature, the fan will turn on. There will be a photosensor, as well as an ultrasonic sensor the fan will use. The ultrasonic sensor will be used to detect the distance of the nearest person. The photosensor will be used to detect light.

Materials


1) Photosensor

2) Ultrasonic Sensor

3) Temperature Sensor LM35

4) Op-Amp IC (LM324/741)

5) Motor Driver IC L293D

6) Potentiometer-10k

7) Propeller

8) DC Toy motor

9)  7805 Voltage Regulator

10) Capactior (100 microF)

11) Multimeter

12) Breadboard

13) Arduino?


Manufacturing Process

  • Use a bread board, which will have the sensors all on it
  • Power bread board
  • Send code to Arduino, which will execute certain commands to the fan under certain conditions


Challenges


  • Effectiveness of sensors
  • Programming skills

Can you all explain more about what features the magic mirror will include with regards to the "information" that will be displayed? Are you all thinking about just displaying the weather or clothing/make-up feedback or time?

Since you guys are a returning project, there is a slightly higher exception for your final project. We recommend to returning groups that they translate their circuit designs to a PCB which we can then print. In addition, we try to strive for higher built quality (i.e. using the machine shop). Other than that, make sure you keep your scope specific and keep on eye on the time. Project approved.

Cool idea!  There's definitely a lot of places you can go with additional features.  I also like the ability to potentially conserve energy using the motion sensor.
