BMP180 Digital Barometric Pressure Sensor Module
Measuring the absolute pressure of the environment using a
digital barometer such as this has some interesting applications. By converting
the pressure measured into altitude, you have a reliable sensor for determining
the height of your robot, plane or projectile! Using a sensor as capable as the
BMP180 you can achieve the accuracy of 1m, with the noise of only 17cm in ultra-high
resolution noise. The device will operate at the only 0.3uA meaning low current
draw for battery-powered applications.
The BMP180 comes fully calibrated and ready to use. As the device operates over I2C we've added optional I2C pull-ups that can be enabled using the PU (pull up) jumper on the board for your convenience and ease during breadboarding.
Using I2C, the device provides pressure and temperature as 16bit values, which are used along with calibration data within the device are used to provide a temperature compensated altitude calculation.
