Application scenarios

KJTLG10-WS laser radar is a new laser ranging solution launched by our company for drones, sweeping robots, industrial robots and other fields. Based on the DTOF ranging principle, this product has small size, low cost, excellent performance, strong resistance to ambient light interference, and can be used as an upgraded replacement product in related fields. This product transmits distance information based on the UART TTL communication interface, which is simple to use, flexible to install and easy to expand. This model adopts a new optoelectronic solution and is very cost-effective.

▼Communication protocol: The UART serial port data output frequency defaults to 500Hz, and the UART serial port baud rate defaults to 460800. Serial port settings: data bit 8, stop bit 1, no parity check.

The following data frame instructions are all in hexadecimal data format

The UART serial port outputs a frame of 4 bytes of data in the following format:

Frame Header	Distance value two bytes		Check digit
5C	02	11	EC

5C: Fixed frame header 1 byte

02 11: The two-byte distance value indicates that the measured distance is 4354mm, in little-endian mode, with a range of 0-65535. If the distance cannot be measured, 65535 is output.

EC: One byte of check digit, starting from the second byte 02 and ending at the second to last byte 11, sum and invert

2. Verification function: The following settings and read command frames all use this verification function

From the second byte to the second to last byte, sum and invert

3. Setting and reading instructions

①Read product serial number

send	5A	0D	02	0D	0D	Check digit
return	5A	8D	02	10	01	Check digit

10 01 means the product serial number is 272: in little-endian mode, the product serial number displayed on the host computer is: S00272 (add S in front of the 5-digit number)
