Banlys MFD
Opt-in multi-sensor readings from phones in the field — magnetometer, motion, light, pressure, and entropy summaries — with documented quality labels. Built for researchers studying environmental and mobile-sensing correlation. Measurement-only: observations, not conclusions.
Where the data comes from
Banlys MFD packages are derived from opt-in research contributions collected through Banlys mobile sensing applications. Packages include multi-sensor readings, coarse location (~100 m), and quality metadata as documented in the data dictionary. They do not include media files or account identifiers. Sharing is voluntary and can be turned off anytime in the contributing apps.
What you get
Researchers receive a versioned MFD field-data package under license. Banlys retains separate internal analysis and tooling outside the public product.
What this is not
- Not medical, safety, or hazard detection
- No photos, audio, video, or emails in research exports
- Not SI-calibrated lab instruments
- Coverage is uneven — honesty over hype

How access works
Apply with a research or institutional email. After review: license acceptance, payment, then delivery of a versioned package (data, dictionary, manifest). Annual Research Access covers releases published during your license term. Not a live API.
