BMP180 Digital Barometric Pressure Sensor Board Module (2B3 Barometric sensor)

Product information
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.
