+/* SFE_BMP180 altitude example sketch
+
+This sketch shows how to use the Bosch BMP180 pressure sensor
+as an altimiter.
+https://www.sparkfun.com/products/11824
+
+Like most pressure sensors, the BMP180 measures absolute pressure.
+Since absolute pressure varies with altitude, you can use the pressure
+to determine your altitude.
+
+Because pressure also varies with weather, you must first take a pressure
+reading at a known baseline altitude. Then you can measure variations
+from that pressure
+
+Hardware connections:
+
+- (GND) to GND
++ (VDD) to 3.3V
+
+(WARNING: do not connect + to 5V or the sensor will be damaged!)
+
+You will also need to connect the I2C pins (SCL and SDA) to your
+Arduino. The pins are different on different Arduinos:
+
+Any Arduino pins labeled:  SDA  SCL
+Uno, Redboard, Pro:        A4   A5
+Mega2560, Due:             20   21
+Leonardo:                   2    3
+
+Leave the IO (VDDIO) pin unconnected. This pin is for connecting
+the BMP180 to systems with lower logic levels such as 1.8V
+
+Have fun! -Your friends at SparkFun.
+
+The SFE_BMP180 library uses floating-point equations developed by the
+Weather Station Data Logger project: http://wmrx00.sourceforge.net/
+
+Our example code uses the "beerware" license. You can do anything
+you like with this code. No really, anything. If you find it useful,
+buy me a beer someday.
