This sensor mode has a variety of ways, the following one list:

* This program uses ds18b20, the following data in the sensor name 0x01, the reserved bits are 0x00

* 0: ds18b20 by default to send data, the time interval of 1 second

* 1: ds18b20 set to Q & A mode, read through the command (the specific command command through the document to explain)

* AIT Sen Technology Agreement Description: 0xff Sensor Name Data Command Data Component Data Symbol Data High Data Low Reserved Reserved Reserved Bit Parity

* Active upload: 0xff Sensor name 0x00 Data component Data symbol Data High data Low Reserved Reserved Reserved Bit parity bit
