Idea:<\/h1>\n

The main idea behind this project is to open the window to cool or heat your room when the outside temperature is what you want your room temperature to be. For example, in the summer, if it is a super nice day out and your room is very hot, you could enter a temperature into the system and it would automatically open the window to let outside air in to adjust the room temperature. This also has a dual purpose in the winter for if your house is too hot and the system could open the window to let a cool breeze in.<\/p>\n

The main components of this system are two thermistors for measuring outside and inside temperature, a motor with an encoder to actuate the window, a motor driver to control the speed of the motor, and a p5 script animating the information from the Arduino in a helpful way. The Arduino sends the data over serial communication to the p5 script which then displays this information to the user and animates the virtual window corresponding to the current motor position.<\/p>\n

As shown in the demo video below, the system works very well detecting a need for opening the window and acting upon it. In addition, the p5 script very accurately shows the degree of openness of the window. While these component work very well together, the controller is still fairly simple. Currently, there is just one setting for open and closed meaning the window doesn’t open a certain degree based off the temperature difference between the room and the goal temp. With more time this feature could be implemented, but for demonstration purposes of this concept, the current controller works well.<\/p>\n

Here are images of the final system concept. The first image is an overall image showing both the physical build and the virtual animation. The second image is a close up of the virtual animation screen showing the displayed outside and inside temperatures as well as the window itself. Finally, the third image shows a top view of the physical wiring for the system.<\/p>\n
