# Pilot 3.30 — protocol design + 2-subject collection

Designed the 30-minute baseline collection protocol that became the [Baseline 4.8](baseline_4.8.md) standard.

## Contents

- `正常人Baseline数据采集_30min精简版.md` — the 30-min simplified protocol (used for 4.8 collection).
- `正常人Baseline数据采集实验方案.md` — the full protocol design document.

## Role

- Protocol prototype.
- Files at [`raw/sensor_data/pilot_3.30/`](../../raw/sensor_data/pilot_3.30/).
- Protocol doc copies in [`wiki/datasets/_pilot_3.30_30min_protocol.md`](_pilot_3.30_30min_protocol.md) and [`wiki/datasets/_pilot_3.30_full_protocol.md`](_pilot_3.30_full_protocol.md).
