Description:

This digital barometer has some interesting applications. By measuring the absolute pressure of the environment and converting this into altitude. you will have a reliable sensor for determining the height of your robot, plane or projectile. This sensor is capable of achieving an accuracy of 1m, with noise of only 17cm in ultra-high resolution. The device will operate at only 0.3uA meaning low current draw for battery powered applications.
