-Devices for data gathering: 
-  * PIR motion sensor 
-  * Screen time  
-  * Smart wearable devices (e.g. Aura Ring) 
- 
-Data points measured:  
-  * Fall asleep time 
-  * Wake up time 
-  * Phone usage after sleep time 
-  * Amount of deep sleep, REM sleep, light sleep, and awake time 
-  * Feedback via self set sleep quality score 
- 
-Analysis: Evaluate the different scores before and after. Make a quantitative and qualitative analysis for final result.

 +| **Metric**                        | **How to Measure**                 | **Expected Change**         |
 +| **Average bedtime**               | Time of last motion/phone use      | Earlier and more consistent |
 +| **Wake-up time**                  | First PIR movement or wearable log | More consistent, earlier    |
 +| **Phone usage after bedtime**     | Screen time log, RFID absence      | Decrease over time          |
 +| **Coffee intake after 5 PM**      | Button press logs                  | Fewer presses after 5 PM    |
 +| **Room conditions**               | Temp/humidity logs                 | More time in optimal range  |
 +| **Nighttime disturbances**        | PIR sensor logs                    | Fewer movements at night    |
 +| **Sleep score**                   | User self-report & wearable data   | Higher over time            |
 +| **Sleep stages (REM/deep/light)** | Wearable logs (e.g., Oura)         | Higher % of deep/REM sleep  |
  
-==== 9. Final Code ====+**Data Collection & Tools** 
 +Sensors and Devices: 
 +  * RFID sensor – Phone detection 
 +  * PIR motion sensor – Movement before and during sleep 
 +  * Button input – Coffee habit monitoring 
 +  * Temperature & Humidity sensor (DHT11/DHT22) – Room environment 
 +  * Smart appliances – Logs of on/off state 
 +  * LCD Screen or App UI – Sleep reminders, feedback, manual input 
 +  * Wearables (Oura Ring, Fitbit, etc.) – Sleep stage and heart rate data
  
 +Storage:
 +  * SD card or cloud logging (e.g., Firebase, Google Sheets)
 +  * Time-stamped logs for sensor data
 +  * Secure, anonymized user logs
 +
 +**A. Quantitative Analysis:**
 +Track changes week-over-week or month-over-month
 +
 +Key comparisons:
 +  * Average bedtime before/after intervention
 +  * Caffeine intake frequency at night
 +  * Sleep duration and stage improvement
 +  * Night disturbances (motion events) reduced
 +  * Use graphs: sleep score trends, usage heatmaps, condition logs
 +
 +**B. Qualitative Analysis:**
 +  * Weekly reflections: user rates sleep quality & experience
 +  * Note perceived stress, restfulness, energy levels
 +  * Interview or survey users to understand comfort, usability
