Temperature calculation method :

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

Example: sendinstruction:A5 45 EA, receivedOne frame of data:

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;
