What the BMP180 does
The BMP180 is a digital pressure sensor featuring piezo-resistive technology for high accuracy and linearity. It operates across a pressure range of 300 to 1100 hPa with a supply voltage of 1.8 to 3.6 V. The device includes integrated temperature measurement and communicates via an I2C interface. It offers low power consumption of 5 µA at one sample per second in standard mode. With a small 3.6 mm x 3.8 mm footprint and 0.93 mm height, it suits mobile phones and GPS devices. Typical applications include navigation enhancement, weather forecasting, and vertical velocity indication for sports and leisure equipment.
