    Communication protocol - VRS-WS-N01-8-EX

    1. Basic communication parameters

    Code8 bit binary system
    Data Bit8 bit
    Odd-even Revi-sion BitNone
    Stop Bit1bit
    Incorrect Revis-ionCRC(Redundant cyclic codes)
    Baud Rate2400bit/s, 4800bit/s, 9600 bit/s options, the factory default 4800bit/s

    2. Data frame format definition

    Using Modbus-RTU communication protocol, the format is as follows:
    Initial structure ≥4 bytes of time
    Address code = 1 byte
    Function code = 1 byte
    Data area = N bytes
    Error check = 16-bit CRC code
    Time to end structure ≥ 4 bytes
    Address code: the address of the transmitter, which is unique in the communication network (factory default 0x01).
    Function code: the function instruction of the command sent by the host, this transmitter only uses the function code 0x03 (read register data).
    Data area: The data area is the specific communication data, pay attention to the high byte of the 16bits data first!
    CRC code: two-byte check code.

    0x010x030x040x02 0x920xFF 0x9B0x5A0x3D

    Temperature calculation:
    When the temperature is lower than 0 ℃, the temperature data is uploaded in the form of complement code.
    Temperature: FF9B H(hex) = -101 => temperature = -10.1℃
    Humidity calculation:
    Humidity: 292 H (Hex) = 658 => Humidity = 65.8%RH
