06 Guidelines

Ø The laser emitted by this ranging module is 905nm , which is safe for human eyes. However, it is recommended not to look directly at the laser .

Ø This ranging module is not airtight. Make sure the relative humidity of the operating environment is less than 70 % and keep the operating environment clean to avoid damaging the laser .

Ø the ranging module is related to the atmospheric visibility and the nature of the target. The range will be reduced in fog, rain and sandstorm conditions. Targets such as green leaves, white walls, and exposed limestone have good reflectivity and can increase the range. In addition, when the target's inclination angle to the laser beam increases, the range will be reduced .

Ø It is strictly forbidden to plug or unplug the cable when the power is on; make sure the power polarity is connected correctly, otherwise it will cause permanent damage to the device .

Ø There are high voltage and heat generating components on the circuit board after the ranging module is powered on. Do not touch the circuit board with your hands when the ranging module is working .
