Product-specific buyer note

The module reports target parameters such as distance, movement state, speed and signal energy; application logic may need to derive a robust occupied/unoccupied decision and tune thresholds for mounting, reflections and multiple targets. Confirm that UART-only SEN0609, rather than I2C/UART SEN0610, matches the design.

India regulatory note

For a finished commercial or safety-relevant installation, verify applicable radio-device approvals, electrical safety and privacy or workplace-monitoring obligations. Do not use a single low-cost radar as the sole life-safety, intrusion or machine-guarding sensor.
