(3) data calculation method Temperature calculation method: High Temperature = 8 << 8 | Low 8 (Actual angle multiplied by 100) ???Example: Send Command: A5 45 EA, Receive Data: <5A-5A- 45-04C-78D-19-A7> ??Indicates TO (signed 16-bit, indicating the target temperature): TO = 0x0C78 / 100 = 31.92C ??Representative TA (Signed 16, on behalf of the ambient temperature): TO = 0x0D19 / 100 = 33.53C ? Description ?The module is the serial data output, the user sends the output command through the serial port connection, for example, 0xA5 + 0x45 + 0xEA to the module, the module will output the temperature data continuously; Query output can send 0xA5 + 0x15 + 0xBA to the module, the module will send back once Temperature data, the query frequency should be lower than 10hz, 10hz for higher use of continuous output mode, then send 0xA5 + 0x45 + 0xEA instruction
