Feature
CJMCU-90614 is a low-cost infrared temperature module.
Working voltage 3-5v Low power consumption and small size.
Its working principle is to read infrared temperature data through single chip microcomputer, serial port (TTL level)
Communication mode output (the baud rate can be set):the baud rate of the serial port is 9600bps, 57600 and 115200bps
There are two ways of continuous output and query output, which can adapt to different working environments and connect with all single chip computers and computers.
Object distance ratio:1.6:1

Data output format
Byte1 frame header logo 0x66
Byte2 frame header logo 0x66
Byte3 data output mode (0x01 continuous output; 0x02 query output, default is continuous output mode)
Byte4 measurement data length (counted by Byte)
Byte5 data 1 high 8 bits
Byte6 data 1 low 8 bits
Byte7 data 2 high 8 bits
Byte8 data 2 lower 8 bits
Byte9 data parity bit (all 8 bits of data are accumulated)
Data calculation method
Temperature = 8 bits of data high
Command instruction (send to MCU, set various parameters)
Byte1 frame header logo 0x66
Byte2 frame header flag 0x66
Byte3 setting command
0x01 continuous output mode
0x02 query output mode
0x11 Set baud rate to 9600
0x12 Set the baud rate to 57600
0x13 Set the baud rate to 115200
Byte4 end of frame flag 0x56
Instructions
The module outputs data for the serial port, connect the module to the power supply, connect the serial port (the default is 115200 baud rate, continuous transmission mode), and the serial port outputs directly. If you want to change the sending method, you can send the command 66 66 02 56 to the module, and then send the command every time, the module will return the temperature data once. If you want to change the baud rate to 9600, you can send 66 66 11 56 to the module. If you want to change the baud rate to 57600, you can send 66 66 12 56 to the module.
