BMP180

The BMP180 is a fully calibrated digital barometric pressure and temperature sensor module with I2C interface. Measures absolute atmospheric pressure with 17cm noise (ultra-high resolution mode) and can be used for altitude calculation up to ±1m accuracy. Ultra-low power draw (0.3μA) suits battery-powered applications. Onboard optional I2C pull-ups via PU jumper.

Note: HW-596 board has identical functionality.
