2. Occupancy Sensor Wall Switch Occupancy Sensor
Senses when room is occupied to switch light on/off
Uses ultrasonic and PIR sensing technology
Saves energy by minimizing unused light
Detects major motion in rooms up to 1000 sq. ft

3. Current Testing Procedure
PIR must be tested to meet NEMA standards to detect minor motion.
Problem: Inefficient and tedious
5-6 min per square
Takes valuable space
No synchronization between control and robotic arm.

4. Current Testing Procedure

5. Requirements Improve current testing process Shorter time Less space
More automation between robotic arm and sensor
Conform to NEMA testing standards

6. Proposed Solution
Rotate sensor to simulate positioning of robotic arm at various locations in the coverage pattern.

7. Proposed Solution

8. Benefits of Proposed Design
Smaller required space
Automated data recording
More efficient

9. Tentative Schedule
