CJMCU-MLX90614 BCC Human Body Infrared Thermometer Non-contact Thermometer Serial Output Module
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 115200bpsThere 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 1letter of agreement Serial communication parameters default baud rate value is 115200 bps which can be set by software Baud rate 9600 bps Check digit N Data bit 8 Stop bit 1Baud rate 57600 bps Check digit N Data bit 8 Stop bit 1Baud rate 115200 bps Check digit N Data bit 8 Stop bit 1Module output format Instruction length 9Data output format Byte1 frame header logo 0x66Byte2 frame header logo 0x66Byte3 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 bitsByte6 data 1 low 8 bitsByte7 data 2 high 8 bitsByte8 data 2 lower 8 bitsByte9 data parity bit all 8 bits of data are accumulated Data calculation method Temperature 8 bits of data high8 bits of data low the result is the actual temperature multiplied by 100 Command instruction send to MCU set various parameters Byte1 frame header logo 0x66Byte2 frame hea
