The following are the same as the "1, Frame head:0xa5

Instruction format: header+instruction+Checksum(8bit)(Such as automatically reading the temperature command= 0xA5 + 0x45 + 0xEA)

2, Command command: 

Continuous output command:

0xA5 + 0x45 + 0xEA ----------------The temperature data (the module returns the data type as0x45)

Query output command:

0xA5 + 0x15 + 0xBA ---------------The temperature data (the module returns the data type as0x45)

Configuration instructions:(Power-down restart after the entry into force)  

Baud rate configuration:

0xA5 + 0xAE + 0x53 --------------- 9600(default)

0xA5 + 0xAF + 0x54 --------------- 115200

Power is automatically sent to the temperature data configuration:

0xA5 + 0x51 + 0xF6 ---------------Power output automatically after power data(default)

0xA5 + 0x52 + 0xF7 ---------------The temperature data is not automatically output after power-up

  SaidTA(Signed16bit, Indicating ambient temperature):TO = 0x0D19 / 100 = 33.53°

Instructions

 The module for the serial output data, the user through the serial port connection, send output instructions, such as0xA5 + 0x45 + 0xEATo the module, the module will continuously output the temperature data; if you want to send through the query output0xA5 + 0x15 + 0xBATo the module, each time the module is sent, the module will return a temperature data, the query frequency should be lower than10hz, If higher than10hzPlease use continuous output mode, that is, send0xA5 + 0x45 + 0xEAinstruction;
