Seeking Input

[ericvic]

Just sitting around thinking up new circuits in my head so I wanted to see what you guys may want. If we (Hobby Boards) were to come out with a general purpose 1-Wire AtoD board what voltages and currents would you like to see it be able to measure, how many channels would you need and how would you like to be able to hook up the devices being measured.

Off the top of my head I think it would be nice to have 10-bit and select between 0-5 and 0-10 volt inputs. Maybe also incorporate one or two digital inputs and digital output on the card as well. Analog input channel numbers would depend on cost, maybe two or four to try to keep it down so you can incorporate several in your system.

This way a user could have several of the devices around the home for various automation purposes. Run one in the attic for heat sensor and trip an exhaust fan (via relay/digital output). Run one in the garage for door sensor/control and water softener salt level sensor and parking indicator (analog inputs).

Screw terminals like the Elk's M1 Gold would be nice for inputs and outputs.

How about 6/12/24 selectable?

Yea, I guess it's arbitrary. I was just thinking of the sensors I use here (five and ten volt maximum outputs).

One other thing, though I don't know if it's possible due to current limits, would be to provide an excitation voltage output so you can have a DC source for your sensors as well.

I'd also vote for (maybe jumperable) 0-2.5/0-5/0-10V, 4-20mA is also a common sensor output..
Quad, mabe close to the HVAC-Monitor but more flexible..

As you asked :hesaid: wishlist:
- A simple IO like the D2P with a DS2406, maybe with a little transistor to boost switchable load a little bit
- What would be IMHO really cool as there's nearly nothing in the market below xhundred$: some kind of real (True RMS) power-meter. as you already threw a uC into the UV-meter AFAIR: I came across the ADE7753 recently..
There are hundreds of plugs but nothing to be put into the distribution with some usable output..
