Functional Description
The system supports single measurement, continuous measurement, and angle 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 Measurement
Triggers a single distance measurement to the target. For low-reflectivity targets, the system automatically repeats measurements until stable distance data is obtained. The measured result is then transmitted via the serial interface in the standard data format.
3.4 Continuous Measurement
In continuous measurement mode, the laser module performs repeated distance measurements on the target. The typical refresh rate is set to 2 Hz or 5 Hz, and the maximum refresh rate can reach 30 Hz (customized version required). The refresh rate can be adjusted via the serial interface.
3.5 Angle Measurement
Angle measurement is available upon request. The system measures the target’s pitch angle within a detectable range of –70° to +70°, with an accuracy of ±0.3°. Internal angle data (X/Y/Z coordinates) can be provided for customer-side development and integration.
