problem water level reef-pi

[figaro93]

hi guys this is my first tread i'm building my reef-pi. and the water level sensor is giving me some trouble.
I used a sensor dfrobot liquid level fs iro02 v1.0 as recommended in the guide by ranjib following the guide as soon as I connect the sensor and interface with reef-pi through my page the plug relay immediately turns on but when I go to insert it into the water is nothing happens.
what can it be?
the links are made on pcb perma proto adafruit and I followed the link perfectly
red on the black 5v on the GRD and green on the GPIO 17
can you help me?
Thank you

Do you have a multi-meter handy so we can check the actual signals/voltages? Also a picture of the connections goes a long way, as it may be easy to spot certain types of errors.

yes I have a multimeter with me what do you need to know? now also place the photo of the links

this is my job
I did not use the central chip because from what I understand you need with the 12v power strip while I used 5v relays because in my country it is difficult to find the power strip that you use and also because I do not have American plugs in the house but being in Italy I have all European sockets ...
if you tell me that the chip also serves for 5v relays as soon as I get there I install it

Show us your connector configuration (inlet) and your ato configuration. Screenshot of the ui will be awesome

I try to explain it to you because I will not be home before 4 hours
Then in setting and connectors I click on the button adjacent to inlets and I write probe rabocco imposed pin gpio 17 and I click on add
then I go in the ATO section click on the plus button and add all the data in the space where it asks me the seconds for the ceck I add 5 and select the socket I want to allocate to the pump of rabocco
as soon as I click on save after 5 seconds the relay turns on and opens the circuit as you say in the guide but also when I put it in a bowl of water the sensor and as if it does not detect that it is in the tank and does not close the relay
tonight's place screen of my reef-pi

here are the pictures of my reef-pi configuration
both outlets and inlets
of equipment and ATO
@Ranjib could you help me?

Your configuration and wiring looks correct. The relay should turn off within 5 seconds of the sensor being out of water. Can you reboot pi, and run the same test (i.e. keep the sensor inside the water for 10 seconds and then outside for 10 seconds) and see if anything changes.
If its still happenning, lets test for continuity and electronics, to nail down if the problem is in hardware of software (highly unlikely). Using a multimeter run continuity test from the pins in Pi (5v, GPIO17 and GND) to the dfrobot breakoutboard , with everything powered down. Then power up and take voltage reading in pi for all those three pins and in the breakout board. Take these voltage reading from these two places (pi and breakout board) when sensor is in water and outside water. Share all these readings. Dont give up, this is not impossible, but it will take time in the beginning. We are with you in this journey

hi guys I just did the test .. both with the probe in the water and with the probe out of the water two connections mark 3.6v and two connections mark 0v so I think it's the sensor that's failed? what I do? do I send the product back and buy something else? also because the management of the power strip through temperature sensor for ignition chiller and heater is working perfectly.

@Ranjib

I think so. But this is rare thing (bad sensor ) . What about the continuity checks? May be some connections are shorted

 

[figaro93]

do you say it's short?
can I try to take a look at the welds or change pin gpio?

 

[figaro93]

I solved the problem ATO as you said you were just a problem of pin gpio that did not send a correct signal. Everything works perfectly. Now I also have a working controller (now the other two are missing) lol Thanks for everything @Ranjib

Woohoo
