= !Pressure/Temperature/Weather forecast sensor (BMP085) =

== Software ==
You can download the Arduino sketch [[https://github.com/mysensors/Arduino/tree/master/libraries/MySensors/examples/PressureSensor|here]].\\

This sensor sleeps most of the time. You can change the sleep interval by updating SLEEP_TIME define at the top of the file. 

This sensor requires you to upload the following device files to Vera as well.\\
https://github.com/mysensors/Vera/tree/master/barometer\\
D_BarometerSensor1.xml\\
D_BarometerSensor1.json\\
S_BarometerSensor1.xml\\

== Wire things up ==

Follow the instructions in ConnectingRadioModule to connect radio module.

To connect the BMP085 sensor to the Arduino board follow these instructions:\\
Connect VCC of the BMP085 sensor to 3.3V (NOT 5.0V!)\\
Connect GND to Ground\\
Connect SCL to i2c clock - on 168/328 Arduino !Nano/Uno/Duemilanove/etc thats Analog 5\\
Connect SDA to i2c data - on 168/328 Arduino !Nano/Uno/Duemilanove/etc thats Analog 4\\
EOC is not used, it signifies an end of conversion\\
XCLR is a reset pin, also not used here\\

== Hardware - Purchase guide ==

To build this sensor you'll need one arduino + radio specified in the base kit found here:\\
