# Use Cases TaτsuOS is application-agnostic, but the following are representative of the deployments planned for the first twelve months. **Industrial sensor networks.** A factory deploys TaτsuOS-enabled vibration sensors. On the Starter tier, devices stream basic 1 Hz telemetry. Upgrading to Builder or Pro unlocks high-rate sampling, OTA firmware pushes, and fleet-wide dashboards — all gated by the monthly TATSU subscription burn rather than a fiat contract with a single vendor. **Agricultural telemetry.** A farm cooperative deploys soil-moisture probes. Each member pays once, in TATSU, to unlock the cellular-uplink feature on the probes assigned to their plot. **Consumer prosumer hardware.** A camera ships with on-device object detection disabled. The buyer subscribes to the Pro tier, which includes access to the AI model layer, and the capability is unlocked via a cryptographic receipt — no separate vendor account, no opaque fiat billing. **Aftermarket vehicle modules.** A retrofit telemetry module ships with basic OBD-II reporting. Advanced features — fleet-grade location reporting, driver-scoring inference — are on-chain unlocks. **Research and educational deployments.** A university lab buys 200 boards for a course. Unlock features per student, per semester, with a clean cryptographic record of who paid for what. In each case, the OEM ships one SKU, the buyer pays once, and the entitlement is portable — bound to the device, not to the buyer's account with the vendor. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
