2. Objective
To build a low cost motion detection device that will detect a human presence.

3. Low cost components Advanced Capabilities for Interfacing
Initial Constraints
Low cost components
Advanced Capabilities for Interfacing

4. Initial Constraints → Results
Low cost components
Advanced Capabilities for Interfacing
→ Components combined price under $20
→ Can program in Arduino IDE and AVRdude (command line terminal)

5. Main Components Adafruit Trinket Mini Pinhole camera
Additional standard electronic components
Pinhole camera

6. Outline Design test circuit
Practical interfacing with microcontroller and camera

7. Outline Programming for: - Successive snapshots - Data Capsulation
- Image analysis
Troubleshooting/debugging
- (Ongoing)

8. Data Capture Due to processing power of hardware:
- Utilize minimal amount of data required to achieve motion detection

9. Data Capsulation Due to processing power of hardware:
- Utilize minimal amount of data required to achieve motion detection

10. Image Analysis
Comparison of two subsequent snapshots from the video feed:

Data
Output

11. Progression Initial interfacing with camera Scripts:
- Snapshot capture
- File handling/Data Capsulation

12. Obstacles Processing information locally
-Remote computer for data analysis?
Tuning for sensitivity
-Detection for people vs anything moving in the frame
