SparkFun Barometric Pressure Sensor Breakout - BMP180

SEN-11824 SparkFun Barometric Pressure Sensor Breakout - BMP180

Description:

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 1.8 V to 3.6 V and is I/O lines are 5 V tolerant; we typically run it on a clean, regulated 3.3 V 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 (1.8 V to 3.6 V)
• Low noise measurements
• Includes temperature sensor
• Low-profile with a small footprint
