It's built-in oled screen can show current data or graphs of data vs time within a scale from the past 2 hours to the past 2.5 days.
Most important, this logger is an open source project.
The logger is based upon a Bosch BMP085 temperature and pressure sensor and an Atmel AVR ATmega328P micro controller.
I built this device about a year ago and often used it.
Unfortunately I once left it in my trousers bag and put it in the wash machine.
Of course it was broken afterwards, the display and the pressure sensor had to be replaced.
I changed them today and now the logger is back and alive again.
Since it is so small I can use it inside an rc controlled glider as an altimeter.
Btw. did I mention it uses an oled display ?!
