The UNESCO World Heritage Site is reopening shortly after being closed during the lockdown since March 10.
The small wearable sensors are a first for a museum in the world. It’s attached to a ribbon that can be worn around a person’s neck and will beep, vibrate and flash when social distancing guidelines are breached i.e. when visitors get within a range of two metres (6.5 feet) of each other. The devices are anonymous, keeping the visitor data safe.
