Thanks for the teardown. Replacement Transformer Started by ncag Today at 7: The CD is recommended instead if it has a single supply voltage.

BrownOut Banned Aug 13, Has anyone here tried using this water alarm as more than just an alarm? Hero Banned Aug 13, It just shares C1 with cd4069ubbe rest of the board.

Thread starter Hero Start date Aug 13, One of the problems is that I can’t find two datasheets from the same manufacturer and different manufacturers are going to vary somewhat.

Selfdischarge will probably be the main driver of that. Here is a graph of the gain and frequency response of dwtasheet CD or a 74C04 Cmos inverting amplifier:. There is no battery low indicator, but at such a low drain it will take years for the battery to need replacement.

It looks like I’ll have to order some CDs or 74C04s then.

What’s the difference between the CD4009 and CD4069?

cd406ube It works well as a linear amplifier. Keep linking good, informative sources. Its great you even were able to build the schematic from it. While in standby, the only power drain is the leakage through C1 and Q1. Your email address will not be published. I’ve read through the datasheets and I’m ashamed to say I’m stuck. What we have here is two essentially independent sections. Articles Top Articles Search resources. Cd4069ubd participate you need to register. With sufficiently conductive fluid touching the two electrodes, the gate of Q1 gets pulled up and it turns on.

Interestingly enough, each stage is doubled — I am guessing for better current supplying capacity at the outputs. Could the frequency of the sound be changed to lets say 1kHz? It also happens to be where the ground trace connects.

Is the answer 60? You must log in or register to reply here. Not much in here and sure looks like the eighties! Today we have a somewhat vintage teardown.

The top one detects water and turns the power on.

The design is nicely compartmentalized, with separate areas for sensor wiring, battery and electronics. The CD is not recommended by Texas Instruments.

These and the CD are logic inverters that are always Un-Buffered. Hero Banned Aug 14, 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. It was fed the signal from a switched-capacitor lowpass filter IC and both were together in a feedback loop.

I drew the chip U1 as seven parts for clarity: Welcome to our site! By continuing to use this site, you are consenting to our use of cookies.

If they are used as a linear amplifier then they self-bias at an output voltage too low and with low gain. Since datashret is no hysteresis, the alarm will shut off the moment contacts stop touching water. In this case the shorter propagation delay through the part, and slightly less complex transfer function means it oscillates at higher frequency and more reliably. Luckily it does not take much to make one on a design this simple.

CD is so old, the datasheet is still from Harris.
