Guest dpaulovich Posted July 18, 2014 Report Share Posted July 18, 2014 I Have an aneometer that outputs 0-2 vdc. I want to monitor that voltage and alarm if the voltage falls below 1.5 vdc.Does anybody have a circuit diagram with parts list?Thanks Dan Quote Link to comment Share on other sites More sharing options...
Hero999 Posted July 18, 2014 Report Share Posted July 18, 2014 A comparator & voltage reference IC will do this.See links below for datasheets:http://ww1.microchip.com/downloads/en/DeviceDoc/22269B.pdfhttp://www.micrel.com/_PDF/mic841.pdf Quote Link to comment Share on other sites More sharing options...
