How long can 4pin light sensor cables be?

Hi Everyone

Currently enjoying my first time exploring sensors as part of a light and sound installation project.

Essentially we want to place four sensors on the four corners of a square with sides approximately 3m long. I am intending to put the Grove board / Arduino Uno on one of these corners, connecting to computer / Max via USB.

My question is regarding the 6m length that the sensor furthest from the board will have to run. Is it possible to get the 4pin cables this long? or is there another, better way to connect?

Many thanks in advance for any advice!
