SEN0676 80-GHz radar sensor - Measuring cycle

There’s no explicit “max measuring rate” listed for the SEN0676 in the datasheet/wiki but in practice you should expect about 1 reading/s (≈1 Hz) as a reliable, conservative figure when using the UART/Modbus interface. Some 80 GHz FMCW level sensors from other vendors advertise update rates “≤1 s” or RS-485 update ≈1 Hz (and 4–20 mA outputs sometimes 1–3 Hz).
