This price is just a piece of module , without the  18B20 sensor,

 

Communication baud rate: 9600.8.N.1        Data format: hexadecimal

Communication protocol and function:

————Read the temperature ————

For example:

A module as a slave communicate with master by RS485,and,read the temperature of 12 ports .

The master send the message as this format:

Send content                                    Bytes        Send data                 Meaning

Slave address                                     1               01                             No. 01 Slave

Function code                                     1               03                             Read register

Register starting address                    2               0004                          The Command of reading

The number of words for reading        2               000C                          Read the 12 words of temperature

CRC check                                         2               XXXX                          The CRC result

 

The slave feedback the temperature value one by one from port0 to port11.

The feedback format from the slave:

Send content                                           Bytes        Send data                 Meaning

Slave address                                            1               01                      No. 01 Slave

Function code                                            1               03                      Read register

Feedback length                                        1               18                      Feedback 24 bytes status value

The feedback date                                    24             00_AC           *port0:  17.2

                                                                                00_B3        port1:  17.9

                                                                                 FF_82        port2:  -12.6

                                                                                 ……..         ……..

                                                                                 FF_B1        port11:  -7.9

CRC check                                                  2               XXXX                  The CRC result

*The 0=”+” H0AC =172 , the value is 10 times of the real temperature, so the real temperature =172/10 =17.2

The F=”-” HFB3 =125(complement) , the value is 10 times of the real temperature, so the real temperature = 125/10 =12.5
