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

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.

Current Testing Procedure

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

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

Proposed Solution

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

Tentative Schedule
