Smart coffee maker / Smart kaffebryggare

Ni, Houbo January 2017 (has links)
Nowadays, more and more people drink coffee not only from Starbucks or other shops, but also brew coffee from coffee maker which with proper sizes which they can be put in the resting room of companies or homes. The products of coffee maker polarize in the market. Some of them have powerful functions and nice tastes with high prices. The others are simple, cheap but losing enjoyment of drinking coffee and people need to keep an eye on status of coffee maker. Most of people prefer the cheaper type. But more functions will take more convenience. Actually users can have them both. In this thesis, I design some functions based on the cheap type of coffee maker which will make drinking coffee more convenient and enjoyable. I use Arduino Uno as my control system, cooperating with sensors and special circuits. My system monitor working time of coffee maker, temperature of coffee and water level of both coffee pot and tank in the coffee maker. Then users can receive these values from their cell phone and doing remote control. Meanwhile considering about prices, I choose the most suitable sensors for measurement. I also do some jobs for saving energy and safe. The system locks or turns off the switch automatically for them. At last, all the sensors, wires and control chip are put in good positions in the maker.
