Custom Lonten New arrive MLX90614 non contact thermometer serial port output module for thermometer Manufacturer

Product features:
Working voltage 3-5v power consumption is small and small.

Infrared temperature data, serial port (TTL level)

Communication mode output (set baud rate) :

The baud rate of serial port is 9600bps, 57600 and 115200bps.

There are two modes of continuous output and query output,

Can adapt to different working environment, with all single chip computer and computer connection.

Serial communication parameters (the default baud rate is 9600 BPS, which can be set by software)

Baud rate: 9600 BPS check bits: N data bits: 8 stop bits: 1.

Baud rate: 57600 BPS check bits: N data bits: 8 stop bits: 1.

Baud rate: 115200 BPS check bit: N data bits: 8 stop bits: 1.
Module output format:

Instruction length 9

Data output format:

Byte1 frame header mark 0x66.

Byte2 frame header mark 0x66.

Byte3 data output mode (0x01 continuous output; 0x02 query output by default for continuous output mode

Byte4 measure data length (by Byte count)

Byte5 data 1 is 8 bits high.

Byte6 data 1 is 8 bits low.

Byte7 data 2 is 8 bits high.

Byte8 data 2 is 8 lower.

Byte9 data verification bits (all data accumulates to 8 bits)

Data calculation method:

The temperature = 8 bits of the data is 8 bits lower than the data, and the result is the actual temperature times 100.
Command instruction (send to MCU, set various parameters)

Byte1 frame header mark 0x66.

Byte2 frame header mark 0x66.

Byte3 sets the command.

0x01 continuous output mode.

0x02 query output mode.

0x11 set baud rate of 9600.

0x12 set baud rate of 57600.

0x13 sets the baud rate of 115200.

Byte4 frame tail mark 0x56.

Usage:

The module is the serial port output data, the module is connected to the power supply, connected to the serial port (the default rate is 115200, continuous transmission mode), serial port direct output. If you want to change the sending mode, you can send the instruction 66, 66, 02, 56 to the module, and then each time the instruction is sent, the module will return the temperature data. If you want to change the baud rate to 9600, you can send 6666, 1156 to the module, and you want to convert the baud rate to 57600 and you can send 6666 1256 to the module.
