Continuous output command:
0xA5 + 0x45 + 0xEA ----------------The temperature data (the module returns the data type as0x45)
Query output command:

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

Temperature calculation method :
temperature=high8Bit< |="" 8="" 8="">low8Bit (the result is the actual angle multiplied by100)

SaidTO(Signed16bit, Indicating the target temperature):TO = 0x0C78 / 100 = 31.92°
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;
