====== Fast analog comparator ACOMP01A ======

[[http://en.wikipedia.org/wiki/Comparator|Comparator]] is used to process high frequency signals. The analog signal input is applied to SMA connector. The comparative level can be set up by a SMA connector as well. Digital output by SATA connector is differential. 

===== The usage of the module =====

  * Conductivity measurements (e.g. for testing a water quality).
  * Measurement of humidity in soil / bulk materials using a [[http://en.wikipedia.org/wiki/Time-domain_reflectometer|TDR]] method. It does not suffer from electrolytic phenomena.
  * Water level measurement (using coaxial cable with chambers, through which the water flows into the dielectric).
