Based on the digital barometer BMP180, this sensor is able to measure the absolute pressure of the environment, converting the measured pressure into a share. Thanks to this sensor will be possible to determine, with a precision of 1 meter, a height that is a robot, an aircraft, etc.. The sensor consumes only 0.5 uA, enabling you to use it on battery-powered devices. The BMP180 is fully calibrated and ready to use. Using the I2C interface provides the pressure and the temperature as 16-bit values, used in conjunction with calibration data within the device are used to provide an altitude calculation of the temperature compensated. Power supply: 1.8 V to 3.6 V, consumption: 0.5 uA at 1 Hz, Interface: I2C, measuring range: 300 hPa to 1100 hPa (+9000 but -500 m), weight: 1 , 18 grams, dimensions (mm): 21x18.
