-/* SFE_BMP180 library example sketch
-
-This sketch shows how to use the SFE_BMP180 library to read the
-Bosch BMP180 barometric pressure sensor.
-https://www.sparkfun.com/products/11824
-
-Like most pressure sensors, the BMP180 measures absolute pressure.
-This is the actual ambient pressure seen by the device, which will
-vary with both altitude and weather.
-
-Before taking a pressure reading you must take a temparture reading.
-This is done with startTemperature() and getTemperature().
-The result is in degrees C.
-
-Once you have a temperature reading, you can take a pressure reading.
-This is done with startPressure() and getPressure().
-The result is in millibar (mb) aka hectopascals (hPa).
-
-If you'll be monitoring weather patterns, you will probably want to
-remove the effects of altitude. This will produce readings that can
-be compared to the published pressure readings from other locations.
-To do this, use the sealevel() function. You will need to provide
-the known altitude at which the pressure was measured.
-
-If you want to measure altitude, you will need to know the pressure
-at a baseline altitude. This can be average sealevel pressure, or
-a previous pressure reading at your altitude, in which case
-subsequent altitude readings will be + or - the initial baseline.
-This is done with the altitude() function.
-
-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.
