Elevator Advertisement - Projection Switch

Triggering Ads projector in elevator. Turn on/off the projector when the elevator door closes/opens to optimize the efficiency.

Features & Benefits:
Active detection mode. The amount of data is smaller compared with the camera-based solution, not affected by ambient light or dark environment,judgement is more accurate and high efficient.

LiDAR sensor can identify the status of elevator gate by monitoring the distance change to the direction of the gate. While the distance is further than its to the gate, it will trigger the projector to turn off.
