  • 1.
    New SDI-12 Commands
    • M5/C5 - Single-ping distance.
      • Returns distance to surface using a single ultrasonic ping rather than a multi-ping median. Useful for rapid measurements or diagnostics.
      • Response: 1 value (distance in meters).
    • M6/C6 - Distance statistics.
      • Returns the median distance along with minimum, maximum, and standard deviation of the temperature-compensated distance measurements from the multi-ping cycle.
      • Response: 4 values (distance, min, max, std in meters).
    • IM5/IC5 and IM6/IC6 identify - measurement metadata responses added for the new commands.
  • 2.
    Measurement Accuracy Improvements
    • Trackback algorithm for time-of-flight measurement.
    • Updated calibration formula.
    • Tuned peak hold window.
    • Improved peak detection calculation.
    • Glitch filter.
    • Skipped pings handled gracefully.
  • 3.
    SDI-12 Communication
    • SDI-12 Interference detection.
    • Improved break detection.
