Making this would take a few components with a fair amount of calibration. Buying a module would be nice. A continuous measurement is always the best, a 10 bit ADC would be adequate.
Here's a link to a project at Arduino Create that might lead you in the right direction. It uses a TI FDC1004 breakout as the sensing circuit.
