title: Ubiwhere Smart Lamppost Dataset

description: About the Dataset

This dataset was collected by Ubiwhere from a smart lamp post installed in the city of Aveiro, Portugal. The smart lamp post is equipped with video and sound sensors (camera and microphone) and captures environmental and traffic-related data.

Time period: Data covers from 2025-08-22 13:10:00 to 2025-08-29 12:00:00.

About the Smart Lamppost

This dataset was generated from a Smart Lamppost IoT installation by Ubiwhere in the city of Aveiro, Portugal.

The Smart Lamppost is a modular urban infrastructure solution that supports:



intelligent LED lighting with remote management and analytics,

optional electric vehicle (EV) charging capability,

edge computing and telemetry,

neutral hosting for 4G/5G telecom services,

environmental sensing (video, sound, noise level, temperature).
