Circiut diagram for Digital High/Low Voltage.......

Dear all,
I have searched the web in vain for circuit diagram of Digital High/Low Voltage Cut Off With Display,but was unable to find the same.
I need the same for my college project along with another project named Humidity Meter.This too I was unable to find.I found this great site instead and I think that you guys will give me some information on both these projects.
Waiting for some posts......


See ya later,

:ranav::

why don't you start by telling us exactly what these projects need to DO?

ie - do you need the humidity meter to output to an LED or LCD display?
and what exactly do you need to control with the high/low voltage cutoff? what level of voltages and currents does it need to sense/control?
and what kind of display are you looking for with it?

Sorry for the incomplete info.You are right.I need the humidity meter to display the o/p on LCD/LED display.

About the Digital High/Low Voltage Cut Off With Display,the limit currents are 22V & 26V,the normal being 24V DC.The voltage should be visible on the LCD/LED display.

The display options are LED or LCD display.I thing LCD display would be better.What do you guys think?

Waiting for some more info...


Regards,
