* Simple code snippet for reading Amphenol | |
* Pressure sensors with I2C output such as | |
* the NPA Series of Surface-Mount Pressure | |
* Sensors NPA-700 and NPA-730. | |

* This basic snippet will likely work for | |
* similar sensors of other brands also. | |
* I used NPA-730B-05WD to test this. It's | |
