[[Image(veraBaro.png, align=right, width=600px)]] = !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:\\ http://code.mios.com/trac/mios_arduino-sensor/wiki/WikiStart#Buyingguide\\ With the following additional parts:\\ 1x [[http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575069610&toolid=10001&campid=5337426682&customid=&icep_item=370810363994&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg|BMP085 Pressure sensor]]\\ TOTAL SENSOR PRICE: $7.6 (arduino + radio) + $3.8 (BMP085) = '''$11.4''' [[Image(baro.jpg, width=500px)]]
