The project is for a dive computer for rebreather equipment...so
Salt water
temperature range appropriate to the marine environment
20 bar for pressure
budget 100$
dimension some cm
may be analog or digital but must measure the absolute pressure. Since this is a prototype and I have not professional equipment that I would not smd.
I see the project diveduino so nice, this project use intersema pressure sensor. I also have that type of sensor but I find it very difficult to solder the pins so I was wondering if you could find some other type of sensor.
best regards
Marco
