I have an anemometer that outputs 0-2 vdc. I want to monitor that voltage and alarm when the voltage falls below 1.5 vdc.
Does anybody have a circuit diagram with parts list.

Thanks
Dan

Welcome to ETO, Dan.

tronitech's advice is good. Also, try googling "Opamp comparators", they are the easiest to understand and construct.

This link is a good start. The link will give you a good overview of voltage comparators. If anything in the link confuses you just ask about it. Scroll down to Comparator Operation as that is a good example of the circuits you want, then move down to Input Offset Voltage And Hysteresis and note what is done. If you really need a drawn circuit after reading the link just ask.
