Just got my BMP085 board. I am looking for a sketch that prints temperature in farenheit and pressure in milibars. If any out there would appreciate a link. Thanks

Here you have also more information about to wire and to program the arduino to read this sensor: http://bildr.org/2011/06/bmp085-arduino/ Enjoy!

Thanks for all the replies. I will have to write some code to convert pressure pa to inches mercury and convert C to farenheit, just have to decide where to put it at in the program, because it has to read the temp before it can produce pressure reading.

I'd put those conversions just before outputting to whatever wants such non-SI units. (OK so degC isn't SI but its closer than degF) Note in particular that inches of mercury is not accurate unless you compensate for local gravity and the temperature, but perhaps you are assuming standard values fo…

So im a fairly new to everything and lastnight I also was looking for a basic sketch to read my BMP085. I used the below code (see link) which is the same code mentioned in this post and it compiled without error so I uploaded it to my Arduino Pro 5v and the serial monitor did not return any informa…

Hi ! I think there is something wrong on your picture serbcccc3 ! Wiring is correct on the Arduino side (if the pin 3V3 on the picture is in fact the 5 V on your board) but you have to put a 3V3 voltage on the pin "LV" (and GND also on the "LV" side) of the logic level converter (connected to the V…

Ok, so if i understand you correctly, on the LLC i have to connect both a low voltage 3v3 and a the high voltage 5v (from arduino)? I thought the LLC drops the voltage down for me?

Correct ! 8) As it is explained on the sparkfun site : http://www.sparkfun.com/products/8745 and on the related schematics : "The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage …

Ok that makes COMPLETE sense now.... for some reason I thought the LLC would drop down the VOLTAGE too..... anyway, can i ask then if i have an arduino pro mini 5v, there is ONLY a 5v source from the board and i would have to dropdown the voltage somehow to power the LV on the LLC right? Sorry im p…

Yes you have to dropdown the 5V voltage to 3.3V ! you can use for example this kind of breadboard with a AA battery: [image] NCP1400-3.3V Step-Up Breakout - PRT-09216 - SparkFun Electronics **Replacement:**[PRT-10967](http://www.sparkfun.com/products/10967). The new version of this board…
