Interfacing BMP180 temperature and pressure sensor on Arduino UNO - #arduino
“Raz” over embedded-lab.com has written a tutorial on how to interface BMP180 temperature and barometric pressure sensor with Arduino UNO board. The BMP180 is a new generation sensor coming on a LGA package and it’s able to measure pressure in the range of 300 to 1100hPa using low power and achieving low noise measurements. The interface is a standard I2C and sensor is fully factory calibrated. The voltage required to power the IC is 3.3V, so your Arduino must provide 3.3V. On this tutorial the data is displayed on a 1.44″ TFT display and “Raz” moved a step further calculating the altitude from the derived pressure. Code and libraries are supplied on the link below.
