The specification of DS18B20 temperature value processing instructions:

 SY AD 02C support a single DS18B20 temperature measurement, the DS18B20 temperature signal from the input SY AD 02C 8-pin (DQ), 9 feet (DGND digital power supply negative terminal) and the 10 feet (5VD digital power supply positive terminal) can DS18B20 external 5V power supply. SY AD 02C only support the the DS18B20 auxiliary power supply work, does not support the parasitic power work. The measurement signal processing by the microprocessor through the serial port can be uploaded to the host communication supports two modes, ASCII and MODBUS RTU mode.

  ASCII mode
  this mode, the SY AD 02C module after receives the data read command (# AA or #AA2, where AA represents the address, channel 3), the data was uploaded to the host. Command # AA is to read the data of all channels, SY AD 02C has three analog signal path, the temperature value is on the third channel. If only to read the temperature value, enter the command # AA2 can make it. (Need to open the third channel; the channel status is set to: 0000 01XX). The data format is: the sign bit (+/ -) and data bits, data bits by the three integers and two decimal places. Such as +023.75 represents 23.75 ° C. If the DS18B20 is not working properly (missed or damage), the module will send the message: C18B20: Prompts the user to check the sensor. In this mode, data can also be transmitted to four hexadecimal data in form to the host, high in the former, including the sign bit and data bits. Convert decimal data; please refer to the DS18B20 data sheet.
Note: The temperature data format does not support a percentage format.
MODBUS RTU mode

This mode, the SY AD 02C module receives a data read command (03H), temperature and analog data acquisition value with the upload to the host, the data for four hexadecimal number, the previous high, the data register address 0003H. Contains the sign bit and data bits, and For DS18B20 collected temperature value is converted to the corresponding decimal value, please refer to the DS18B20 data sheet. In this mode, if the DS18B20 missed or damaged, the module will send a fixed value of 0025H.
