I'm asking to see if there was a way to determine that pressure so the box could be opened in a room with the same pressure to not trigger the sensor. | |

Adding further suggestions.

| Dec 22, 2014 at 5:13 | comment | added | Time4Tea | Also, why do you need to know? Do you actually need to do this for real, or is it a theoretical assignment question? | |
| Dec 22, 2014 at 5:12 | comment | added | Time4Tea | Yes, that was my idea. I'll post another couple of ideas, in case you can't measure the container beforehand. Are you able to experiment with another similar container - pressurize/depressurize, etc.? | |
| Dec 22, 2014 at 3:27 | comment | added | user68162 | I assume you must first measure the dimensions of the container with no pressure in it, then measure the dimensions of the pressurized container and compare the two, right ? | |
| Dec 22, 2014 at 3:26 | comment | added | fibonatic | @AndréDaniel you can calibrate the setup by putting known pressures inside the container. It is actually more about the pressure difference between the inside and outside, so you could also apply different pressures on the outside. | |
