You need to pay attention to data acquisition circuits that use a input mux and
a sample and hold circuit like that used by the BBB analog circuits. When the
ADC samples the analog input, it charges a small capacitor (sample and hold)
and then the ADC converts the voltage stored in the
i'm attempting a build.
I will be using 5 pressure sensors. here are the specs:
Pressure Range: 0-200 psi
Output: 0.5V – 4.5V linear voltage output. 0 psi outputs 0.5V, 100 psi
outputs 2.5V, 200 psi outputs 4.5V
Working Temperature: -40—+125ºC;.
Accuracy: ±1%FS;
Thread: 1/8"-27 NPT.
