Description:

This is a breakout board for the Bosch BMP180 high-precisionlow-power digital barometer. The BMP180 offers a pressure measuring range of 300 to 1100 hPa with an accuracy down to 0.02 hPa in advanced resolution mode. It's based on piezo-resistive technology for high accuracyruggedness and long term stability. These come factory-calibratedwith the calibration coefficients already stored in ROM. What makes this sensor great is that it is nearly identical to its former revthe BMP085!

This breadboard-friendly board breaks out every pin to a 5-pin 0.1" pitch header. VCC can be from 1.8V to 3.6V and is 5V tolerant; we typically run it on a cleanregulated 3.3V supply. The analog and digital supplies (VDDD and VDDA) are tied to a single header pinbut are separately decoupled. It connects to a microcontroller via I2C bus (also known as TWIor on the Arduinothe  Wire  library)
