## Description

This is the retail version of our [BMP180 Breakout Board](https://core-electronics.com.au/search/?q=11824). This is the same as our regular barometer, but in retail packaging.

 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).

**Features:**

- Digital two wire (I²C, TWI, “Wire”) interface
- Wide barometric pressure range
- Flexible supply voltage range (1.8V to 3.6V)
- Ultra-low power consumption
- Low noise measurements
- Factory-calibrated
- Includes temperature sensor
- Low-profile with a small footprint
