 Topic: NiChrome resistance wire
Posted: January 01 2014 at 6:27pm |
|
Does anyone by any chance in their electronics bins have some resistance wire, NiChrome (Nickel Chromium) or even platinum resistance wire. I need to build a probe for my arduino controller to monitor conductivity to determine salt concentration in myh aquarium. I only need 4 pieces of maybe 4 inches each? I can buy a 100 feet of it for not much on ebay, but had rather pay one of you a couple of bucks instead of buying a ton.
Let me know please. OR, if you know some place locally that sells it.

You can use the element out of toasters too. I usually prefer the toaster ones as they are straight single wires unlike blow driers that usually have a coiled element that tends expand quite a bit when heated.

You can use the switch and controls from the blow drier if they still work. That way you don't have to build the power box. You will have two heat settings and the fan is the part that usually goes out on a blow drier anyway. Krazie

I saved the controls for other things, I needed the wire to build an EC probe to monitor salinity.

I'd live to see your circuit diagram and sketch for thes salinty probe.

I have an aquarium shield for the arduino that has the EC circut on it. starting with the code that goes with the shield, it is the Macroduino code. Going to tweek it/ modify it to make it the way I want it. Going to push the data to a MySQL database when I get that far. still playing with different things and learning the arduino.
The homemake ec probe is from the guy who made the shield for the Arduino. Here is the link to the video where he goes through building it.

The shield comes from Practicalmaker.com. Here is the documentation on the aquaium shield.
