Functional Description
The whole machine has functions such as single measurement, multiple measurements, and angle
measurement.
3.1 External circuit enable
Enable this module to work normally.
3.2 External circuit disable
Turn off the external circuit to save power consumption.
3.3 Single measurement
Trigger a single target distance measurement. For low - reflectivity targets, it will automatically repeat the
measurement until stable distance data is obtained. Then, it will report the data in serial port form according
to the standard data format.
3.4 Multiple measurements
In the continuous multiple - measurement mode, it will trigger the laser module to continuously measure the
distance of the object. The typical value of the refresh rate is set to 2HZ or 5Hz, and the maximum refresh
rate can reach 30Hz (customization required). This refresh rate can be adjusted through the serial port.
3.5 Angle measurement
If the customer has the need for angle measurement, it can be customized. The pitch angle of the target is
measured, and the detectable angle range is -70° to +70°, with an angle accuracy of ±0.3°. Internal angle
information (X/Y/Z coordinates) can be provided for the customer's own development.
