This is a mischaracterization of Berkeley's position.
Berkeley did not admit even the existence of the senses, much less that they convey anything to us, nor the unstated assumption of the above description that there's something outside our senses to be conveyed to us through the senses.
To Berkeley, everything that exists is either a perception in the mind or the mind itself.
Berkeley's writing is very accessible and clear, entertaining even. To anyone interested, I strongly recommend reading his "Three Dialogues Between Hylas and Philonous"[1] where he leads you through his thinking step by step. I wish more philosophers wrote as well as he.
