The heisenberg uncertainty principle is a relationship between certain types of physical variables like position and momentum, which roughly states that you can never simultaneously know both variables exactly. Informally, this means that both the position and momentum of a particle in quantum mechanics can never be exactly known.
The heisenberg uncertainty principlestates that it is impossible to determine both the position and the velocity of an electron simultaneously the detection of an electron, for example, would be made by way of its interaction with photonsof light. The observation of an electron with a microscope requires reflection of a photon off of the electron.
It says we cannot know the position of a particle and its momentum at the same time and tells us the limit of how well we can know them. If we try to localize a particle to a very small region of space, its momentum becomes uncertain.

See, the heisenberg uncertainty principle is about quantum mechanics, which happens on a microscopic scale.
