Set the default slave ID to 1, function code 04, starting address 0, quantity 2

Now the computer reads the sensor data every 1 second, and the measurement (line 0 and line

1) is shown in below picture, after dividing the measurement by 1000, it is the true temperature

value, 28300/1000 = 28.3 °C

On the right, you can check the raw sent and received data packages.

When the temperature is positive:

1. Host sends 01 04 00 00 00 02 71 CB

2. Slave responses 01 04 04 00 00 6E 8C D6 41

3. Return temperature data 0x00006E8C (Hex), converted to decimal = 28300, get the

corresponding air temperature by dividing through 1000, air temperature = 28300/1000 =
