Evacuation plan for concert
LED direction with RN2483 ,RN2903, P2P
In the past, building interior evacuation diagrams – These floor plan diagrams are posted at selected locations in buildings with interior corridors, hallways and/or offices. They show the locations of building exits and the pathways of travel to these exit. The exit plan should change with different scenario. Some time, people run to dead end and get hurt. 

With long distance LoRa, we have sucessfully built dynamic exit direction plan with LED and RN2483.  BACK
