My build.

[Ruben Wijnhoven]

Ok how do i do that? I know how to open serial monitor in arduino but how do I enable cariage return?

[Fernando Garcia]

[Ruben Wijnhoven]

Tnx it took me a while before i figured out you have to run these commands with the stamp testcode. But it worked it is running at 38400 now

[Fernando Garcia]

Hi!

Just to clarify,

Atlas have changed the default baud rate to 9600. I'm sorry was looking to old datasheet.

Best regards.

[Ruben Wijnhoven]

I know that's what i meant. I fixed it by running the serial,38400 and now all is wel. I also added this to my install tips and tricks.

[Ruben Wijnhoven]

Everything is still working great. I added a ph stamp. I can now make my aquarium cooler fan run when it get's to hot. And i added a 433 transmit module to the ferduino so I can switch on my wireless power sockets in my home (klik aan klik uit). I can now switch on remote my hd-camera to have a nice life feed of my aquarium, and see if my flow pump is running. I am actually done now. Evertything is working exactly how i want it too. So what i have is:
3 temp probes running
1 ezo ph stamp running
1 cooler fan running when it get's to hot.
1 float switch that get's triggerd if my return pump stops (send an ph reactor alert to my e-mail)
1 433 wireless communication to power sockets that now controll my hd internet camera.

So fernando thank you for bringing this awesome product.

[Fernando Garcia]

Hi!

Some pictures and video should be nice.

Best regards.

[Ruben Wijnhoven]

I will see if i can make some nice pictures tomorrow. I have one thing i would like to fix but it is just for the niceness of it. I still have a littebit noise on my ph readings (see picture or click link):
https://dyp.im/fIiN6fj5w9

The max of those reading is correct i testes this with my other ph measurement. So i would want to take say 10 readings and then only use the max of those 10 readings. That way I would filter out the noise. Any tips on how to go with that idea, or maybe you have a different idea?

[Fernando Garcia]

Some time ago I did a code to remove delay and use a average of 8 values but, I had not good results using all stamps together.

Maybe it can help you.

The code is to stamps V 4.x, adjust for EZO.

The code take 23 values but, discards 15.

I am trying all day but I can't get your code to work with the ezo stamps. This is my modified code. I first only want to use ph so i removed all the extra code. Plus don't mind all the println, I use those to test how far my code goes.

Hi!

Try learn how it works firstly, it isn't copy and paste only.

My code is using reading continuous so, you can't send a "R" on loop or "C,0" on setup.

Try this:

Code: Select all

const int multiplexadorS0Pin = 16; // S0
const int multiplexadorS1Pin = 17; // S1

byte ph1 = 0; // Y0
byte ph2 = 1; // Y1
byte orp = 2; // Y2
byte ec = 3;  // Y3

int ORP = 0;
int DEN = 0;
float PHA = 0.0;
float PHR = 0.0;
long millis_antes = 0;

Best regrads.

[Ruben Wijnhoven]

thank you just tested your code. I doesn't get pas "stage 2". I will try some more.

[Fernando Garcia]

Try change the interval maybe 10 seconds isn't enough to EZO stamp.

Code: Select all

 if((millis() - millis_antes) >= 10000)

[Ruben Wijnhoven]

I got it working now . Now to integrate it in the main code.

[Fernando Garcia]

This code isn't ready to make what you told above.

You need sort values to discard the bad values.

[Ruben Wijnhoven]

Fernando I integrated the code in my main code. And now it looks like my ph readings are steady now. Will monitor the next couple of days. I decided to take the average of 10 readings instead of 8. will monitor with my other ph reader also so i know the offset and incorporate that.

[Ruben Wijnhoven]

Here are some pics. I use a 3 euro curver storage box that i hacked up. cheap and splash water proof and easy accesible.

[Ruben Wijnhoven]

This is my ph curve after i made the change to the new code, much better .

[Fernando Garcia]

Hi!

Glad to hear.

To post images copy link from "Image-URL" instead "Image BBCode".

I'm curious to know what you did to control your webcam using Ferduino.

Best regards.

[Ruben Wijnhoven]

I bought a 720p wireless ip cam which has a built in webserver. I use ferduino to control it's powersocket throuhg 433 wireless. So i use ferduino to turn the camera off and on from everywhere in het word. I only want the camera to be on when i want to check the tank. For the rest it has to be of.
