Guide for BMP180 barometric sensor with Arduino

sensor-1-e1476437557395

A how-to on using the BMP180 barometric sensor with the Arduino from Random Nerd Tutorials:

The BMP180 barometric sensor (model GY-68) is the one in the following figure (front and back view). It is a very small module with 1mm x 1.1mm (0.039in x 0.043in).
It measures the absolute pressure of the air around it. It has a measuring range from 300 to 1100hPa with an accuracy down to 0.02 hPa. It can also measure altitude and temperature.
The BMP180 barometric sensor communicates via I2C interface. This means that it communicates with the Arduino using just 2 pins.

  1. But the BMP180 is being phased out, and is out of stock at Mouser.com. You might look at the BMP-280 or BME-280 instead.
