Info
 
The BMP180 is an ultra-low power, low voltage capable digital barometric pressure, temperature, and altitude sensor. The I2C interface allows for easy system integration with a microcontroller. The BMP180 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability.

This module includes an on-board voltage regulator (MIC5205 marked KB33) so you can connect the module's "VCC" pin to a 5V supply, such as an Arduino's 5V supply pin. If you want to supply the module with 3.3V then connect a 3.3V supply to the "3.3" pin on the module, which will bypass the on-board voltage regulator.

On-board pull-up resistors are connected to the I2C pins, so you won't need to worry about adding them to your I2C lines. These resistors pull-up the I2C lines to the 3.3V output of the on-board voltage regulator so you can connect the I2C pins directly to a 5V logic device such as an Arduino without having to worry about logic level shifting. They are also connected to the module's "3.3" pin for when you are supplying the module with a 3.3V supply.

IMPORTANT: The BMP180 is sensitive to moisture. Do not submerge or spray the sensor with water or solvents. See page 26 of the datasheet (link provided below) for moisture sensitivity details.

Not so accureate as the BME280 but a great sensor! February 10, 2017
By: ovide mercure from boca raton, FL United States  
This sensor is great for home projects or tinkering.  Programming for AVR is easy as i2c examples abound.  I assume Arduino has this locked up but I cannot speak for this.  The only issue I have found (and it may be my own fault) is that the temperature and humidity don't seem to track within tolerance.  Definitely worth the money.

I'm gonna have some fun with these. December 27, 2016
By: Brian C. O'Rourke from WAYNESBORO, VA United States  
Addicore is my new place to look for inexpensive electronic components.  I ordered and my stuff arrived  in no time and I got free shipping with my purchase in excess of $25.

Sparkfun compatible April 24, 2016
By: CJ from ID United States  
I used this with the sparkfun library and found it easier than the adafruit version. Very accurate sensor, works great.

Good Boards January 18, 2016
By: Kurt Roesener from San Diego, CA United States  
While these do as their intended to, I found a variance between the 2 that I bought, about 2 or 3 degrees, but it doesn't happen all the time.
