Very nice tear datwsheet and very in depth. First time I have seen the uCurrent being used as well. But at room temperature and at least on this unit it was in nA. 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. The lowpass filter reduced the 3rd harmonic distortion caused by the compression. Thread starter Hero Start date Aug 13, To participate you need to register.
Another strain relief on the battery wires to go over case plastic. The enclosure is not sealed and if water level keeps rising past the sensing compartment, there is no guarantee that the alarm will stay functional. The sensors could be local, or remote using supplied wire.
Selfdischarge will probably be the main driver of that. Datssheet you have any info on the buzzer, such as a part number? When alarm is on, the current jumps to around 11mA. I need to get one of those. Has anyone here tried using this water alarm as more than just an alarm? Replacement Transformer Started by ncag Today at 7: R1 keeps gate of the FET pulled low, to keep it off. Thanks for the teardown. It eatasheet Source and Drain cd406ube swapped in silk.
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. It’s not on the datasheet.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at The CD is recommended instead if it has a single supply voltage. It works well as a linear amplifier.
CD is so old, the datasheet is still from Harris. None of my meters could resolve it even when in uA range. Articles Top Articles Search resources. The CD parts that are for sale these days always have a U after the number, that is CDU and this is important.
The top one detects water and turns the power on. Hero Banned Aug 14, Its great you even were able to build the schematic from it. Here is a graph of the gain and frequency response of a CD or a 74C04 Cmos inverting amplifier:.

Interestingly enough, there is not even a dedicated decoupling cap on U1. A classic application for an unbuffered part is when it is used as a clock oscillator. They sink 50mA but source only 8 ma with a 10V supply and an output voltage of 5V. While in standby, the only power drain is the leakage through C1 and Q1. I made some fairly low distortion 0.
The part runs from 3 to 18V, allowing direct operation from the 9V battery. Datasheets, Manuals or Parts. The CD has symmetrical source and sink currents but not as high as 50mA.

THey have different power supply schemes and the output circuitry is different. BrownOut Banned Aug 13, Board back- all throughole. This alarm has a pretty simple task- sit somewhere quietly and watch for water leak. The spec for 2N lists 1uA as a max leakage with no datawheet voltage. Your email address will not be published.
What we have here is two essentially independent sections. The design is simple and pretty clever with essentially no battery drain until triggered.
