Digital barometer
This barometer uses the absolute pressure sensor MPXA4115A, 12-bit A/D converter and AVR ATmega8. The source code and schematic are here. The result is displayed on graphical LCD with TOSHIBA T6A04 controller. In the first half are numerical value of actual pressure in milibars and on second half are bars that represent pressure in last 30 hours (15 bars with 2 hours measuring period). horizontal antermittent line represent pressure of 1000 mb.

Can this be used as a switch? based on the readings?

I don’t think it can be used as a switch as is, but with a couple of tweaks it’s possible.

You wouldn’t happen to still have the source code for this project? The links above are all dead. I Was interested in using the same display(TI-83+ GLCD T6A04A) for a custom power supply I’m building, was hoping your source code could help me drive the display with an atmega328p.

I’ve checked the links and it appears the whole domain is down. I do not have any source code or information related to the project, I was simply linking to an external place. I’ve also tried searching for alternative places where it might be hosted but no luck. Sorry

Ok, thanks. Guess I’ll just have to create the functions I’ll need to interface with the display from the datasheet. Thanks again
