Usage Guide
▶ The laser emitted by this ranging module is 905nm, which is safe for human eyes, but it is still not recommended to stare at the laser directly.
▶ This ranging module is non-hermetic, so it is necessary to ensure that the relative humidity of the use environment is less than 70%, and the use environment should be kept clean and hygienic to avoid damaging the laser.
▶ The measuring range of the ranging module is related to atmospheric visibility and the nature of the target. The measuring range will be reduced in fog, rain, and sandstorms. Targets such as green foliage, white walls, and exposed limestone have good reflectivity, which can increase the measuring range. In addition, when the inclination angle of the target to the laser beam increases, the measuring range will be reduced.
▶ It is strictly forbidden to plug and unplug cables when the power is on. Be sure to ensure that the power polarity is connected correctly, otherwise it will cause permanent damage to the equipment.
▶ After the ranging module is powered on, there are high-voltage and heating components on the circuit board. Do not touch the circuit board with your hands when the ranging module is working.
