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! Adafruit 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 power

Using the sensor is easy. For example, if you're using an Arduino, simply connect the VIN pin to the 5V voltage pin, GND to ground, SCL to I2C Clock (Analog 5) and SDA to I2C Data (Analog 4). Then download Adafruit's BMP085 Arduino library and example code for temperature, pressure and altitude calculation. Install the library, and load the example sketch. Immediately you'll have precision temperature, pressure and altitude data. We also have a detailed tutorial so you can understand the sensor in depth including how to properly calculate altitude based on sea-level barometric pressure

    Great little product, easy to set up on the raspberry pi and provides so great info. It's practically half a weather station. (Posted on 29/11/2014)
