This project is designed for elders or person with disabilities. The mechanism can automatically turn on and off the light as a person comes in the room. especially when the patient doesn't have the convenient to do so. in addition to that, we also implemented a "fall detection" system, which will send notification to our phone application to report this accident.
We used the Adafruit ESP32-S3 as the microcontroller. It is in charge of the wifi function and storage of all the code needed for the project. In this project, we used Python to code. This code tells the microcontroller when to let every part move
The Servo is controlled by the Adafruit 8-Channel PWM or Servo Feather Wing, which was used to turn on and off the light switch.
We chose servos for this project because they are maneuverable based on the degree of movement. In combination with our phone application, it allows users to calibrate the switch after installation, as every wall and switch is different.
We decided to use 18650 batteries to power this project, because it is powerful and reliable. The reason we didn't use AC power is that we want it to be independent of the cable that powers it, allowing it to be used in any circumstance.
Our battery hub also allows the switch to operate when plugged directly into an outlet, if needed.
The motion sensor form Adafruit is used to detect moving object, in this case, human. The use of motion sensor allows the light to turn on automatically when a person enter the room.
3D printing is used to manufacture the parts and frame of this product. Using 3d printing will allow us to design custom parts that have a tight fit for all the electronics. We will also use Flame-Resistant PETG (FR-PETG) to ensure the safety of our product.
This is the first version of Switch Care. This version only has the ability to turn on and off the lights remotely but has proven the feasibility of this design of using only servos to turn on and off the lights. It also shows that a small device can sit on top of a normal light switch and control it without needing to change the wiring. It can connect to a phone so the user can control the switch from far away. It works as a basic proof that the idea can be built and improved in later versions.
