1db GY-MCU90614-BAA soros port IR érintésmentes, infravörös hőmérsékletmérő modul MLX90614-BAA GY-MCU90614-DCI/BAA/BCC
1pcs GY-MCU90614-BAA serial port IR non-contact, infrared temperature measurement module MLX90614-BAA GY-MCU90614-DCI/BAA/BCC
Add the output of body temperature measurement mode for reference body temperature output (only for reference)
Measurement distance (when temperature measurement is not compensated):
DCI / BCI: accuracy within 15cm is about 0.5 degrees higher
BCF: accuracy within 10cm is about 0.5 degrees higher
DCC / BCC: 5cm internal accuracy is about 0.5 degrees higher
Baa AAA: 3cm internal accuracy is about 0.5 degrees higher
The forehead can output body temperature directly, and can add compensation adjustment value for calibration and distance adjustment, power down and save.
Infrared IR non-contact temperature measurement module MLX90614 module serial port direct output data, small size, default no welding row
USB to TTL serial port module is needed to connect the computer
1. Provide computer software to view data
2. Provide Arduino program
3. Provide 51 MCU program
4. Provide STM32 program

Current: 5mA
Baud rate: 9600 or 115200
Default auto output frequency: 10Hz
Measurement range:
-40… 125 ° C for ambient
-70… 280 ° C for measuring target temperature
Size: 21.5 L * 23 w * 22.5 H
-----------------------------------------------------------------------
communication protocol
Serial port send command bytes:
1) , serial port communication parameters (default baud rate value 9600 BPs, which can be set by software)
Baud rate: 9600 BPS check bit: n data bit: 8 stop bit: 1
Baud rate: 115200 BPS check bit: n data bit: 8 stop bit: 1
(2) Module output format, each frame contains 10 bytes (HEX):
① . byte0: 0x5a frame header flag
② . byte1: 0x5a frame header flag
③ . byte2: 0x45 data type of this frame (0x45: temperature data)
④ . byte3: 0x04 data volume (the following 4 data groups 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 previous data byte0-7 is accumulated and only the lower 8 bits are left)
⑩ . byte9: 0x01 ~ 0x15 ID number, range 0x01 ~ 0x15 can be modified, default is 0x14
（3） . data calculation method
Temperature calculation method:
Temperature = high 8 bits < < 8 low 8 bits (the result is the actual temperature multiplied by 100)
Example: sending instruction: A5 45 EA, receiving one frame of data,
<5A- 5A- 45- 04- 0C- 78- 0D- 19- A7 >
To (signed 16bit, object temperature): to = 0x0c78 / 100 = 31.92 ℃
Indicates ta (signed 16bit, indicating ambient temperature): to = 0x0d19 / 100 = 33.53 ℃
(4) , command byte, sent by external controller to gy-mcu90614 module (HEX)
1. Frame header: 0xa5
Instruction format: frame header instruction checksum (8bit) (for example, auto read temperature instruction = 0xa5 0x45 0xea)
2. Command command:
Automatic output instruction (module outputs data by itself):
0xa5 0x45 0xea -------- temperature data (module return data type is 0x45)
0xa5 0x55 0xfa -------- measure the temperature value of forehead output (the data type returned by the module is 0x45)
(temperature output range is 34-41 degrees in forehead temperature mode)
Query the output temperature instruction (send the instruction once to output the data once):
0xa5 0x15 0xba -------- temperature data (module return data type is 0x45)
(temperature output range is 34-41 degrees in forehead temperature mode)
Query the output emissivity instruction (send the instruction once to output the data once):
0xa5 0x25 0xca -------- emissivity setting parameter, data type is 0x25
(decimal 100 for 1, decimal 50 for 0.5)
Query output temperature offset command
0xa5 0x35 0xda -------- temperature offset configuration value, data type is 0x35
(the decimal 100 is the zero point offset, the above 100 is positive, the below 100 is negative, 1 value is 0.1 degree.)
Use ID to query output instructions:
0xa5 ID sun -------- temperature data (module return data type is 0x45, sun is the sum of the first two data)
Modify ID instruction:
0xa5 0XAA ID sun ------ (power down save ID, sun is the sum of the first three data, take the lower 8 bits)
