Hello! You all have always been so helpful, so I was wondering if you could help me again...
I am using the 527-NPA-600B-015D Differential Board Mount Pressure Sensor. It is an Uncalibrated mV sensor. The complete datasheet is attached, and so is the particular page concerning this sensor. Anyways, the project I am attaching it too has an Atmega328 as the microcontroller. I want to know how to use this particular sensor just like the schematic says. (Wiring it straight to the Analog 0 pin on the Atmega). But the doc mentions a Sensor Interface Negative Output and a Positive Excitation. Am I just supposed to use two Analog pins and just compare the difference between it?
If you could help create an equation to apply after I get the differential value to turn that into a readable PSI value I would appreciate it. The docs don't mention a min and max value so I am not sure what to do without testing it, but I cannot do that without a circuit. THANK YOU!!!!!!
