1. What are the influencing factors of laser range sensor measurement?

The color effect of the target object, the target material ground factor, the metal smooth surface

2. What is the laser wavelength in the laser distance measurement sensor?

Laser wavelength refers to the output wavelength of the laser, which is an important parameter of the laser output beam. Generally, the visible light wavelength that can be clearly distinguished by the human eye is basically between 400nm and 700nm. Seakeda laser sensor uses a visible laser with a laser wavelength of 620nm-690nm.

3. Is the laser distance sensor greatly affected by outdoor factors?

The laser ranging sensor is mainly affected by the following climatic factors: moderate to heavy rain, dense fog, strong light, etc., will make the data output of the sensor have gaps, so when selecting the sensor model, you can contact our technology to provide selection suggestions .
