The sensor uses a Class 2 laser (output power < 1 mW), which is generally safe for the eye but direct staring should be avoided.
Wipe the sensor with a soft, slightly damp cotton cloth; do not use corrosive or volatile cleaning agents.
No, the sensor must not be immersed in water even though some models have an IP67 rating.
