Figure 2 Diagram for serial port connection
Note:

Separately supply power from 5V DC stabilized power supply, and do not use 5V power
supply of USB2TTL adapter.

Input voltage range of 4 ~ 6VDC, ripple wave is less than 20mv. Unclean Power supply
will result in the appearance of a number of fixed interference frequency components in the
spectrum during the algorithm analysis, which would have an impact on test results and result in
the continuous target output in a certain fixed distance.

The TX and RX pins of the USB-to-TTL adapter need to be cross-connected to the TX and
RX pins of the NRA15 sensor.
3) USB serial-port adapter is connected to PC. And then open the PC test software to
configure parameters like in figure 5 (plug connection cable into the computer, then open the
PC software, the software will automatically detect the port). The red part in the figure is
parameter configuration of NRA15, while the blue part is the adjusted coordinate range
