Grab'eM BMP180 Pressure & temperature & Altitude Sensor Module(Blue)

This precision sensor from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. Because pressure changes with altitude you can also use it as an altimeter! The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins.NEW! We now have a fully 5V compliant version of this board - a 3.3V regulator and a i2c level shifter circuit is included so you can use this sensor safely with 5V logic and powerThis 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 3.4V to 5.5V and is I/O lines are 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).
