portable pressure&temp device with BMP085

by gergogyerek on Fri May 24, 2013 5:19 am

I'd like to make a portable device that operates from battery and measures temerature and barometric pressure (BMP085 sensor) and displays it on a screen (Nokia 3330?)
I'd like to do the programming part (for learning) but i'd need help with the hardware.
What components do i need to buy?
- Nokia Display
- BMP085 sensor
- battery
- Arduino???
- ...

This would be my portable bike computer, and the battery should last >24 hours.

That list of parts should be enough to get you started. The Arduino UNO is the most general and widely supported version:


For the "finding out how everything works" and "testing ideas to see if this version of the code does what I want" stages, I'd suggest getting a breadboard and some jumper wires too:

http://www.adafruit.com/products/239 - full-size breadboard
http://www.adafruit.com/products/64 - half-size breadboard
http://www.adafruit.com/products/153 - jumper wire bundle

You'll also need some bits and bobs like resistors to limit the current for the LCD's backlight, plus a power supply and a USB cable to connect the Arduino to your computer. Our Arduino Budget Pack includes most of the above:


plus a few LEDs and a few other pieces of common circuit furniture to make experimenting more fun. Our Arduino Starter Pack is pretty much like the Budget Pack, but also contains a Protoshield kit so you can build your final circuit as a shield that plugs directly into the Arduino:

When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
