Q1 along with the forward drop of D1 determine minimum voltage the circuits operates at- around 4V, well beyond a typical 9V battery end of life.

This alarm daatsheet a pretty simple task- sit somewhere quietly and watch for water leak. They also might melt. Replacement Transformer Started by ncag Today at 7: Keep linking good, informative sources. For a better experience, please enable JavaScript in your browser before proceeding. Since there is no hysteresis, the alarm will shut off the moment contacts stop touching water.

The CD is not recommended by Texas Instruments. Luckily it does not take much to make one on a design this simple. Trying to use a 2n mosfet to trigger an alarm panel.


The spec for 2N lists 1uA as a max leakage with no gate voltage. Interestingly enough, there is cd4069ibe even a dedicated decoupling cap on U1.

A Cmos inverter makes a pretty distorted output because its output compesses the signal near the rail voltages. It’s not on the vatasheet. Articles Top Articles Search resources.

These and the CD are logic inverters that are always Un-Buffered. That app note was a great read! The rainwater comes into quadrant III, and reaches the finished room before it gets to the drain or the sump. Nice attention to details. The CD has symmetrical source and sink currents but not as high as 50mA. To participate you need to register. cc4069ube

The design is nicely compartmentalized, with separate areas for sensor wiring, battery and electronics. Leave a Reply Cd4096ube reply Your email address will not be published.

Welcome to our site! No wonder these things last forever on a battery. Here is a graph of the gain and frequency response of a CD or a 74C04 Cmos inverting amplifier:.

What’s the difference between the CD4009 and CD4069?

The part runs from 3 to 18V, allowing direct operation from the 9V battery. None of my meters could resolve it even when in uA range.

By continuing to use this site, you are consenting to our use of cookies. Its great you even were able to build the schematic from it. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at The design is simple and pretty clever with essentially no battery drain until triggered. With sufficiently conductive fluid touching the two electrodes, the gate of Q1 gets pulled up and it turns on.

But at room temperature and at least on this unit it was in nA.

When alarm is on, the current jumps to around 11mA. I drew the chip U1 as seven parts for clarity: CD is so old, the datasheet is still from Harris.

Selfdischarge will probably be the main driver of that.
