This is a breakout board for the Bosch BMP180 high-precision, low-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 accuracy, ruggedness and long term stability. These come factory-calibrated, with the calibration coefficients already stored in ROM. What makes this sensor great is that it is nearly identical to its former rev, the 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 clean, regulated 3.3V supply. The analog and digital supplies (VDDD and VDDA) are tied to a single header pin, but are separately decoupled. It connects to a microcontroller via I²C bus (also known as TWI, or on the Arduino, the “Wire” library).

very good product

I’ve just tested this product and it works pretty well !
I don’t know if it’s me or not but the sensor sends sometime a difference of almost 2 m even if I don’t move it, probably a rounding problem in my calculation.

Awesome product…electrodragon sure stocks up some great stuff at cheap prices 😉

Works pretty well with code from https://github.com/sparkfun/BMP180_Breakout_Arduino_Library but the reading can vary by ~0.1 millibar with it sitting on my desk and set to the highest precision level. (This is equivalent to a ~ 1meter / 3 foot range in reported altitude.)
These things are tiny! The picture of the product shows the 5 pin version, but when I ordered these I received one with only 4 pins (it did not have the 3.3v pin broken out, and there was only one mounting hole). That was fine with me, that just meant less room taken up on my board. 🙂 The ones I got were 10.5mm x 13mm. I had actually wanted to buy the bmp180 chip on its own and integrate it onto my sensor board, but you can’t even buy the bare chip for this price.

Worked as expected. This was my first order with the company and no issues, everything arrived as expected. I will continue to order from Electrodragon as they are friendly and response to email issues/questions.

As usual ElectroDragon comes through again. This is why I always order with these guys. You can’t go wrong.

Works great, very accurate temperature sensor.
