Time error of WT901SDCL-BT50 /WT901SDCL sensor

  Time synchronization of the sensor is achieved by retrieving the system time from the PC software and then writing it into the sensor's register via command instructions. When writing the time data to the sensor, some latency may occur. The latency of each instruction cannot be guaranteed to be exactly the same. Typically, after the sensor completes time calibration, the resulting time deviation is around 5 milliseconds.

  Therefore, even if three sensors are calibrated simultaneously through the PC software, their timestamps may not be perfectly aligned, and a deviation of several milliseconds may still exist.
