The delay time and detection area
The module has three pins by default, namely
VCC, GND and OUT.The delay time and detection
distance are fixed values. If you need to adjust the
delay time and detection distance and other related
parameters, you need to add RX and TX pins as
shown in Figure 3.
The RX and TX interfaces in the figure3 can be
used as UART ports to adjust module parameters.
When they are used as UART ports, please refer to
the document "AirTouch radar setting tool
instructions" for detailed instructions. If the sensor is
triggered again within the delay time, the timing will
start again.
