This indicator lights up when someone is already inside a shop, room or other space. It's designed to show that the area is occupied. The bottom section is made to hold an ESP32 or ESP8266 chip connected to a neopixel ring placed above the light guide part. You can find source code for ESP32/ESP8266 at https://www.hackster.io/benedikt-hubschen/office-busylight-1a8e30.
