# opensensor.space

> Cloud-native sensor data platform using Parquet and object storage. Edge devices stream data directly to S3-compatible storage in Parquet format, visualized with Evidence.dev and DuckDB-wasm. No databases or backend servers required.

## About

opensensor.space is an open-source IoT data platform that eliminates traditional infrastructure complexity. Sensors write directly to cloud storage using Parquet files, enabling cost-effective, scalable environmental monitoring.
