Functional Description
The system supports single measurement and continuous measurement functions.
3.1 External Circuit Enable
Enables the module for normal operation.
3.2 External Circuit Disable
Disables the external circuit to reduce power consumption.
3.3 Single-Shot Measurement
Triggers a single distance measurement. For low-reflectivity targets, the module will automatically repeat the measurement until stable distance data is obtained, and then reports the result via the serial port in the standard data format.
3.4 Multiple Measurements
In continuous measurement mode, the laser module performs continuous ranging with a typical update rate of 2 Hz, and a maximum update rate of up to 10 Hz.
