Summary

This is part of smart warehouse project - smart beacon.
It is designed to stay on pallet with goods and show to warehouse workers which pallet can they ship out. It is connected to WiFi and reading some data from warehouse system database.
In testing version it last almost 4 days on 4x AA battery, so it is sufficient to cover whole shift.

It is basicaly ESP32 with WS2812(neopixels) ring. I have just added one temperature/humidity sensor(it is not on the pictures, there is power sensor INA226 instead), just because i could:)

It is easy to print, top cover is from transparent filament.
Fusion360 file included.
