# Team members: Chaehee Lim (chaehee2), Kevin Choi (kevinsc2), Kevin Yu (Yuey8) # PROBLEM: As working from home has become more popularized, people have become more accustomed to sitting in their rooms all day. However, many workers may not be getting consistent sunlight from their windows while being preoccupied with work and neglecting to angle their blinds accordingly. To get a consistent level of sunlight, a person needs to frequently adjust their blinds, and not doing so will mean that a person may be getting more or less light from the window than intended. # SOLUTION: We propose building blinds that adjust its angles based on a user’s desired level of brightness using a pulley that pulls on the blind’s strings. This could be done using a light sensor to detect how much sunlight exists outside and another sensor to detect how much sunlight is actually coming in. With the data from these sensors and the current time from the device’s real-time clock, the device will adjust the blinds based on the current brightness level and also the time, where a desired brightness level may vary throughout the day. The device’s behavior based on these two factors may be adjusted through an application, which can cater to a user’s specific need. # SOLUTION COMPONENTS: ## SUPPLY Blinds - - The physical blinds would be the ones blocking the sun. Motor - - The motor will be attached to a pulley system that directly manipulates the wires and controls the angle of the blinds. 2 photosensors - - First photosensor will read the output from the outside window to record the maximum brightness so that the user knows the maximum sunlight that can be brought inside the room - Second photosensor will be well within the room connected via bluetooth or wifi to abstain the general brightness of the room itself to make sure that the desired amount of sunlight is entering the room. - From the data of these two sensors, we will automate the adjusting of the blinds to match a desired brightness level up to the maximum brightness available outside. Real time clock - - The device will read the time and influence the adjusting of the blinds by what time it is App - - The user will be able to customize the desired brightness level with a real-time component where the brightness of the blinds matches this level with the adjustments of the blinds. - We will implement a base control algorithm within the device where the purpose is to adjust the blinds to a specific brightness level, but to adjust the threshold for this algorithm (as the maximum sunlight throughout the day changes), we can do so by changing values on the application. - We would like to also add a scheduling component so that the user can schedule that they want X amount of sunlight at X time. We could try to suggest how much can come in at that time based on how much sunlight usually comes in during the day (more in the morning, a lot at noon-ish, none at night) # Subsystem #1: Pulley device The pulley device will determine whether to adjust the blinds. The device will include a motor that adjusts the blind’s strings, and an arduino containing a real-time clock. This device will receive light sensor data via wifi/bluetooth transceiver module and will control the motor based on the light sensor (Subsystem #2) and time data received. Ideally, the device will adjust the blind’s angles so the room can have a user’s desired brightness level throughout the day, where this level may vary as the day progresses. # Subsystem #2: Photosensors We will have two photosensors spread out across the room connected to the pulley device (Subsystem #1) via wifi/bluetooth transceiver module. The first photosensor will read the output from the outside window to record the maximum brightness so that the user knows the maximum sunlight that can be brought inside the room. The second photosensor will be well within the room to abstain the general brightness of the room itself to make sure that the desired amount of sunlight is entering the room. # Subsystem #3: Application We will have a mobile application that sets a brightness level manually and this allows the blind system to operate accordingly. On top of that, the application will support a schedule utility that determines the working hours of the blind system. Also, a recommendation algorithm will be incorporated into the application and suggest brightness level for users depending on the time of the day. # CRITERION FOR SUCCESS: - The photosensors can accurately read the brightness and adjust the blinds through the motor in real-time in conjunction with the real-time clock - The blind adjusting should be relatively quiet and not bothersome to anyone inhabiting the room - The photosensors should be small and not visually distracting - The application can adjust the criterion of what brightness level the blinds always prioritize adjusting to |
