Interestingly enough, each stage is doubled — I am guessing for better current supplying capacity at the outputs.
When alarm is on, the current jumps to around 11mA. The design is nicely compartmentalized, with separate areas for sensor wiring, battery daasheet electronics. Trying to use a 2n mosfet to trigger an alarm panel. It also happens to be where the ground trace connects. One of the problems is that I can’t find two datasheets from the same manufacturer and different manufacturers are going to vary somewhat.
It was fed the signal from a switched-capacitor lowpass filter IC and both were together in a feedback loop. Q1 along with the forward drop cd069ube D1 determine minimum voltage the circuits operates at- around 4V, well beyond a typical 9V battery end of life.
There datassheet no battery low indicator, but at such a low drain it will take years for the battery to need replacement. That app note was a great read! Hero Banned Aug 13, The bare board is made on week 17 of Forums New posts Search forums.
With sufficiently conductive fluid touching the two electrodes, the gate of Q1 gets pulled up and it turns on. And now on to the schematic. Your email address will not be published. Leave a Reply Cancel reply Your email address will not datashdet published.

The rainwater comes into quadrant III, and reaches the finished room before it gets to the drain or the sump. Thread starter Hero Start date Aug 13, Do you have any info on the buzzer, such as a part number? Very nice tear down and very in depth. A Cmos inverter makes a pretty distorted output because its output compesses the signal near the rail voltages. Media New media New comments Search media. Keep linking good, informative sources. The part runs from 3 to 18V, allowing direct operation from the 9V battery.
Note strain relief loop around the plastic post. Today we have a somewhat vintage teardown.

Has anyone here tried using this water alarm as more than just an alarm? C2, I guess, is to even out any voltage spikes when the gate changes state? It’s not on the datasheet. Where did you get that graph from? Dattasheet looks like I’ll have to order some CDs or 74C04s then. dc4069ube
If they are used as a linear amplifier cx4069ube they self-bias at an output voltage too low and with low gain. Another strain relief on the battery wires to go over case plastic. Its great you even were able to build the schematic from it. You must log in or register to reply here. The bottom one is just a driver for the buzzer.
I already have loads of CDs in my junk box, I’m just wondering if it’s worth buying some CDs as well. They also might melt. The CD is not recommended by Texas Instruments. THey have different power supply schemes and the output circuitry is different.
BrownOut Banned Aug 13, None of my meters could resolve it even when ddatasheet uA range. I made some fairly low distortion 0. Welcome to our site!
