BMP180 is a high precision, small size, low energy consumption pressure sensor. It can be used in mobile devices. Its performance is excellent, the absolute accuracy can achieve 0.03hPa (minimum), and low power consumption, only 3μA.
The BMP180 uses a powerful 8-pin ceramic leadless chip carrier (LCC) ultra thin package that can be directly connected to various microprocessors via the I2C bus.
Typical applications:
GPS accurate navigation (dead reckoning, upper and lower bridge detection etc.)
Indoor and outdoor navigation
Leisure, sports and health care and other monitoring
Weather forecast
Vertical speed indicator (rising / sinking speed)
Fan power control
