Will this work ? monitor temps and power

Post by eric256 »

Sorry - fixed the links

I'm working on a project to monitor temps and KWH's. Peter Anderson makes a nice kit, that has optoisolators going to a pre-programmed PIC processor. http://www.phanderson.com/iom142/iom142.html

I plan to use a bunch of DS18s20's for the temps, and then some small CT's for power.

The CT's are the main question. I plan to use these . http://www.controldepot.net/index.asp?P ... tegory=804, but I'm not sure which one is correct for this kit.

Anyone have any experience or opinion?

(yes - i've worked with electrical wiring a lot before - and know the dangers ................)

Aloha.

Interesting, the first link doesn't work, but when you go to his homepage and click on the link it works. Both are the same... go figure :???:

The period at the end of the posted link causes the 404 failure.

without the ending period works for me.

after a quick look at the interface board i think the easiest way to measure current is to use the A/CTE series CT that output a o to 5V Dc voltage based on the current.

To read this into the interface board i think that you will need to use a Dallas D" 2450 IC that has 4 A/D input channels. then the V command on the interface board will read in the required voltage.
