by Coregleam co.,ltd

What is VLC underwater?

Scuba Divers can talk and hear each other and one another If they bring our water-resistance LED Flash-Light under the water. The system which uses LED lights as a medium for underwater communication. The device works by first taking sound and converting it into a light signal. The LED light will then transmit the signal to the other person’s receiver where it is reverted back to sound.

The LED underwater communication system was originally only able to send signals from a distance of 1 meter, but now divers are able to converse within 30 meters of one another. The device can be battery powered for up to 4 hours. It is also not constrained only to communication between divers underwater, but can also send signals to someone on land from underwater. There currently are plans to minimize the size of the device in the future
