the probe is a k=.99 which is the same. The higher the number the less accurate. K=.1 is good down to .5 uS, 1 down to 5uS and 10 is good for 10uS

Is the expansion hard coded to not return below 6ppt? The probe is a K=1 rated and goes down to 5uS. (7 ppm). That is the middle ranges probe.

love the baby bottles!

Can you tell me what JP1 and JP2 are for? Right now they are both completely open. 6ppt is not low enough for anything in freshwater. The readings that are important are around 5-200 ppm (~0-400 uS)

Thanks for being patient with me as I muddle through this!

The minimum value of the salinity module can measure is 6ppt. That's why you get 6 showing up. Anything lower than that will require a different probe, but we are really not interested in less than 6 ppt anyway. Not sure what was going on, but this will let the pump go on when it finds 6ppt: if (Re...

Not sure how I missed the 0 in channel.

Like
X = analogRead( i2cio-pin1)

Also didn't find newer Eagle files

And how do you send data to pin 1 vs pin3? I get the example above except for this.

I'm pretty new myself. Been up and running about a month freshwater so not as complicated but doing some things similarly. But to take a stab at your question that is exactly what I found and am doing. Here is a link to a great overview someone did that helped me out tremendously. He answers your qu...

Thanks Curt! I am using the wormy apple app Do you know if the portal, badges, etc can have the unused expansions turned off? Makes the screen look like lots is broke. (Freshwater and unlikely to use ORP)

I read about the PCF8574 chip on TI's site. Seems straight forward - less complex than using the 328P. But the question remains. How do I get more than just an on/off value from it?

BTW - I cannot seem to locate the 2.2 eagle files for IO on the download page.

[quote="rimai"]As input, it is easy. if (ReefAngel.IO.GetChannel(0)) { } After learning how I2C works and seeing how it is used then reviewing the schematic I have come to Understand that the is a I2C slave based off the 328p. With that in mind I looked back at all the code libraries Espec...

I figured out that i needed to download the Labels from the server and then nulls were replaced by 5 waterlevel tags. Is there anything i need to do for IO Expansion values? I havent seen anything of them popup.

Wow that is plenty easy enough. But one question. Which of the 6 will that data be sent to?

Thanks!

yea, i have an opto isolated relay like the sainsmart i had from a netduino project.

i am not an expert, but i do know the basics about electronics. I will mostly be driving a relay for my 5v/12v stuff.

I will use some as input only and some as outputs

Is there a way to turn off the modules on my banner, portal and app that i dont use - like ORP? Also on the app it looks like the Water Level is listed as null along with 4 additional values. They do not have values but the 1st one I can see is the water level. Can I set the label somewhere for the ...

I just got my Water Level and IO Expansion and Expansion hub yesterday. Got the WL all calibrated and it is working GREAT! Should have done this long ago. I do daily water changes and by using the high and low ATO memvars I can dial in EXACTLY how much water to drain before turning the ATO back on. ...

"you use the mask" - is that the mask or the override? 1.) So the heater is set with the automatic out of the box on/off function (from the wizard) 2.) Some problem is detected in code maybe 3.) ReefAngel.Relay.Override(heater_port); 4.) Heater stays off forever until Override is overridde...

Can someone help me understand what/how Override and Mask works with regards to relays? What is it for and how is it used?

Is anyone doing anything with Electrical Conductivity? (EC)

Is ther any way to monitor EC values for my tank? I am doing planted freshwater.

Ran the macro and mine is up and running now!! Thanks!!! I did have a bump in the road as I was trying to do the update with my pc connected to the Head Module - doesnt work that way - ha! The minute I plugged the USB cable into the WiFi module, the terminal program did its thing and all is well. Al...

It appears that on my portal, the data for the relay graphs end at 4pm on DEC 23rd. Same goes for Temp and PH. Is there something that I have done to make it stop? Here is my code: #include <ReefAngel_Features.h> #include <Globals.h> #include <RA_Wifi.h> #include <Wire.h> #include <OneWire.h> #inclu...

Aren't the level sensors that come with the RA+ simply switches?

I have a non-contact water level sensor that I am trying to get to work with my RA. I have scoured the forum and have not been able to find any code snippets. But I have read in several places that both the ATO ports and the "extra" temp probes can be re-purposed. I have looked at the sche...
