The original MLX90615 chip, medical grade accuracy.
Serial send command byte:
(1), serial communication parameters (default baud rate 9600 bps, can be set by software)
Baud rate: 9600 bps Parity: N Data bits: 8 Stop bits: 1
Baud rate: 115200 bps Parity: N Data bits: 8 Stop bits: 1
(2), module input command sent by external controller to GY-MCU90615 module (hex)
1, frame header: 0xa5
Instruction Format: Frame Header + Command + Checksum (8bit) (Such as automatic read temperature command = 0xA5 + 0x45 + 0xEA)
Continuous output command:
0xA5 + 0x45 + 0xEA ---------------- temperature data (the module returns the data type is 0x45)
Query output command:
0xA5 + 0x15 + 0xBA --------------- temperature data (the module returns the data type is 0x45)
Configuration instructions: (power-down restart after the entry into force)
Baud rate configuration:
0xA5 + 0xAE + 0x53 --------------- 9600 (default)
0xA5 + 0xAF + 0x54 --------------- 115200
Power on automatically send temperature data configuration:
0xA5 + 0x51 + 0xF6 --------------- Automatically output temperature data after power on (default)
0xA5 + 0x52 + 0xF7 --------------- Temperature data is not automatically output after power-on
Serial port to receive:
(1), serial communication parameters (default baud rate 9600 bps, can be set by software)
Baud rate: 9600 bps Parity: N Data bits: 8 Stop bits: 1
Baud rate: 115200 bps Parity: N Data bits: 8 Stop bits: 1
(2), module output format, each frame contains 9 bytes (hexadecimal):
① Byte0: 0x5A frame header flag
② Byte1: 0x5A frame header flag
③.Byte2: 0X45 The frame data type (0X45: temperature data)
④ Byte3: 0x04 data volume (the following four groups of two data as an example)
⑤.Byte4: 0x00 ~ 0xFF Data 1 high 8 bits
⑥.Byte5: 0x00 ~ 0xFF Data 1 low 8 bits
⑦.Byte6: 0x00 ~ 0xFF Data 2 high 8 bits
⑧.Byte7: 0x00 ~ 0xFF Data 2 low 8 bits
⑨.Byte8: 0x00 ~ 0xFF checksum (the sum of the previous data, leaving only the lower 8)
Temperature calculation method:
Temperature = high 8 bits << 8 | low 8 bits (result multiplied by 100 for actual angle)
Example: Send command: A5 45 EA, received a frame of data: <5A-5A- 45- 04- 0C- 78- 0D- 19- A7>
Indicates TO (signed 16bit, indicating target temperature): TO = 0x0C78 / 100 = 31.92 ° C
Indicates TA (signed 16bit, ambient temperature): TO = 0x0D19 / 100 = 33.53 ° C
Instructions
The module for the serial output data, the user through the serial port to connect, send output instructions, such as 0xA5 + 0x45 + 0xEA to the module, the module will be continuous output temperature data; If you want to send the query output 0xA5 + 0x15 + 0xBA to the module, each Send once, the module will return a temperature data, the query frequency should be less than 10hz, for more than 10hz use continuous output mode, that is sent 0xA5 + 0x45 + 0xEA instruction;

Note: The module I / O is TTL level, which can be directly connected with the serial port of the microcontroller. It can be directly connected with the chips such as PL2303, CH340 and FT232, but not with the 9-pin serial port of the computer
