How I implemented system integration in My final project
1. Sensor Integration
Light, Temperature, and Humidity Sensors: Connected to the Xiao ESP32-S3 microcontroller, these sensors continuously measure environmental data crucial for determining optimal wake-up conditions.
Microphone: Monitors ambient sound levels, including sleep-related noises, to refine wake-up timing based on sleep phases.
2. Data Processing and Decision Making
The Xiao ESP32-S3 microcontroller processes real-time data from all sensors, making decisions based on algorithms that analyze the data against set parameters to initiate the wake-up process.
3. Actuator Control
Speaker: Activated under optimal conditions to play natural sounds or predefined audio files, gradually increasing in volume to ensure a natural wake-up.
Control Interfaces: Allows manual setting adjustments and provides environmental condition feedback through a user-friendly interface.
Neopixel LED Ring: I used a Neopixel LED ring as part of the output signaling system. The LED ring changes colors and patterns based on the environmental conditions detected, providing a visual indication of the wake-up phase or ambient atmosphere.
4. Feedback Loop
User interactions with the alarm, such as snoozing and shutting off, are recorded and used to adjust wake-up algorithms for personalized experiences over time.
5. Software and Hardware Integration
All hardware components are integrated through a circuit board with the Xiao ESP32-S3 microcontroller at the hub. The custom software handles sensor data acquisition, processing, decision-making, actuator control, and LED pattern control. Future software updates can integrate additional features like voice control or health monitoring.
6. Testing and Validation
Comprehensive testing ensures all components work synchronously under various conditions, validating sensor accuracy, wake-up mechanism effectiveness, and LED output responsiveness.

Included the license I chose
All aspects of my final project were designed by myself, without borrowing from other sources.
Some parts of the code were checked and modified using GPT.
Acknowledged work done by others
First, I want to thank my mentor Salman Faris for the guidance and advice he provided on PCB design during my Final Project, which allowed me to fully grasp this area of knowledge.
I would also like to thank my classmate Matthew, who helped me learn many programming techniques during the coding process.
Thanks to my classmate Dion, who introduced me to the ISA fablab, allowing me to complete some learning content on time.
Additionally, I am grateful to Katherine for teaching me how to use MQTT.
Of course, I must not forget teachers Jiawei and Crail for their collaboration during our team assignments. Everyone was very effective, performed their roles excellently, and took their responsibilities seriously.
Once again, I want to thank my family for their support while I participated in the FAB Academy course.
During this time, my beautiful daughter was born, and although her arrival initially made me worry about delaying my course deliverables, it ultimately gave me more confidence to complete the FAB Academy assignments.
I am committed to completing all assignment reviews by July 22.
