Group Members: Hersh Singh (hksingh3), Derik Lee (dhl2), Louis Wright (louisw2) Problem: The biggest use of electricity in housing is used in maintaining temperature in buildings. By using the outside temperature to cool down or heat up a house will save energy expenditure. For example, leaving a window open at night in the summer can cool the building down. People aren’t always aware of the difference in temperature when inside a room, thus they constantly have to experiment with how open the window should be. This is a very inefficient way of trying to regulate the desired temperature because the human senses are not as accurate in detecting and calculating changes in temperature and other factors such as humidity, and precipitation. Solution overview: We propose making a window that opens and closes automatically when a sufficient temperature differential between the inside and the outside of the building occurs. We will be calculating the temperature inside and outside and then calculating how large the opening of the window should be to get the desired interior temperature. In addition to this, air quality will be monitored to ensure that the air that is being entered from outside is not adding a hazardous amount of pollution. We will also be displaying humidity inside the room and figuring out precipitation outside to make sure that the window stays closed and does not allow for rain or snow to enter the room through the window. Finally, as a precaution we will be checking to see if there are any obstructions in the path of the window, thus having a safety mechanism. Solution components: Sensor Subsystem - The sensor subsystem will measure the following parameters: Temperature, Humidity, Rain. This information will then be passed onto the processing subsystem. These are going to be the inputs of the project and will dictate which state and action the regulator takes. Another IR sensor will be placed as a safety feature in case there is any obstruction. They will be have to be powered as well as send data to the microcontroller. We will also have a switch or button for setting a desired temperature that will be fed into the microcontroller as well, which will be our target temperature to reside around. We will use a hygrometer for humidity levels, a thermometer for temperature, a variable resistor for rain detection, and optical dust sensor for air quality. Processing Subsystem Given the data from the sensor subsystem, the processing subsystem will send a signal to open or close the window(s). This will receive the data from the sensors and also have to be connected to power.The input from the user must also be used to compare and calculate constantly. Once the sensors data is received, it must do the calculations with both of these readings and determine what action and state to go to. This decision will send data to the motor system which either opens the window a certain amount or closes it. Power Subsystem: This system powers all the sensors, microcontroller and the motor subsystem. We are deciding to power the system through a wall since we intend to have constant polling and sensor reading throughout the activity. Motor Subsystem: The motor subsystem is used for controlling which way the window opens and closes and how much. To dictate this decision, the system will be connected to the control subsystem which will send data through to produce an opening or closing motion. Criterion for Success: The criterion for success will be the sensors give correct readings to the microcontroller for the sensory subsystem. From there depending on the desired temperature the correct data is being sent out from the processing subsystem on whether to open or close the window. Finally, the motor subsystem using this data must act accordingly and either open or close the window the desired amount. |
