... Serial.println("*******************************"); Serial.println(); delay(5000); } The initial status is different between sensors in default code but it doesn't matter. In default code the normal status is: http://www.ferduino.com/forum/gallery/image.php?album_id=11&image_id=299 ...

... a question to this post? The "duration per stage" variable for partial water change is just for safety? everything is driven by level sensors, is it right? but if something goes wrong the time limit force the system to finish the TPA routine, maybe indicating that it was not ok. Am ...

... incredible multi-tank system..obviously managed with Ferduino...as you probably most of you well know... Some question for Fernando about level sensors. In Ferduino code they are used as analog signals, doing things on the basis of the fact that their reading is >400 or <400. For my understanding ...

... - USE_PINS_18_AND_19_FOR_RTC - anything attached at the moment (probes, sensors, relays) - WIFI - connected the ESP8266 with the level shifter per ... this is not a "robust procedure". then i connected the temperature probes and they are not working, but if I will not be able to ...

Hi! Welcome Kloster! I can't see reason for this type of usage since the temperature in a water tank should be equal after a while. There others topics about add more sensors. http://www.ferduino.com/forum/viewtopic.php?f=24&t=129 http://www.ferduino.com/forum/viewtopic.php?f=8&t=151 ...

Ok. Got it. Thank you so much!

... Connect the level sensors wires directly to mono jack phone. There only two points to connect wire on connector and the polarity doesn't matter. Connect the temperature sensors wires directly to mono jack phone. Follow the schematic. ...

... and perform right connection on the DB25 connector? that's right? for temperature sensor, can i buy a AS18B20 classic sensor and buy this one for ... level sensor? which adapter can I buy for making the connection between sensors and board easy as Fernando thought? thank you so much!

Thank you very much for your answer. I didn't know the problem about parasite mode, maybe the problems that I had was only that I was running the sensors in parasite mode to save 1 cable...
Thank you very much!

Hi! You can work with many sensors without problem using sensors in normal mode not parasite mode. In parasite mode maybe the current will drop so much. Also the wire should be the more short as possible. You should make the code by yourself, ...

... something is going wrong reduce the power to all of them. That function is already implemented in Ferduino code, my question is if I can add more sensors without slowing the code (in the past I had - with other systems - some errors with multiple reading maybe because the DS18B20 aren't too fast ...

The level status is not related with chiller status.

Check the function "void check_nivel()" to see the conditions.

If sensors 1, 2, 4, 5 and 6 are not connected you will get random status.

If you don't want connect this sensors put fake pin numbers on code.

... using the ethernet shield, like random ASCII characters in the bottom of the screen, so i decided to remove it for now. I connected the temp sensors and all seems to go well. Do i need to waterproof them? The next thing i' m planning to connect is the heater. It uses pin 42 right?

... I connected the temperature sensors and tested them. I decided to use a pcb board for the wirring. So far so good: http://www.ferduino.com/forum/gallery/image.php?album_id=52&image_id=537 ...

... very stable and accurate readings from probes. the next step is to change the Ferduino code (as needed) to implement the I2C mode for the atlas sensors- I am still figuring out how this part of your code functions. As I am still waiting for my LCD, I am fiddling around with your code. btw. If ...

hello my friend any help for the pins of leds timers temp sensors?
i need other pcbs?


sorry for my english isnt very good

... not available when you designed your original PCB. I have looked at the PDF and it suggests that conductivity will interfere with the other sensors, and that it must be separate to the isolated serial expander.
