A highly sensitive barometric pressure sensor for weather, industrial, rocketry, balloon, and many other pressure sensing applications.

The sensor is designed for use as a micro-altimeter so it has incredible resolution: so sensitive it can detect an altitude change of just 13cm! Move it up and down and you'll see the output values change.
