About Sensor Observation Service

Sensor Observation Service is a wireless sensor network site indexed in the SENTINEL Directory — the open AI-curated web directory built to revive the spirit of DMOZ and the Yahoo Directory. SENTINEL maintains and verifies sites across 900+ categories, replacing the dead human-edited directories Big Tech killed between 2014 and 2017.
