I deleted all my libaries catalog and unpack mysensors 1.4. Previous was 1.5. Too many options what i do not understand. After work i try again and to let you know from results.

This is not moisture sketch. I try with different sketches.

Maybe need change nrf? I try.2016-07-04 15:42:12.816 MySensors: Gateway Ready...

Version 1.5 should work if you do it right. It does for me.
In your case the sensor can't seem to get any connection to your gateway.
You should try adding a capacitor to the radio, check your power supply and change the nrf module. These are the reasons for most errors imo (especially the power supply)

There are extra Threads/Topics to finding an error with your setup here in the forum. I think this doesn't really belong to this thread anymore.

Okay. I search

This might help.

Today morning i can say : working. I bought arduinos 3,3v 10 pcs from Aliexpress. Yesterday i change this to 5V pro mini and this sensor get work. I take picture from this Arduino. Maybe 5volts not 3,3. Voltage stabilizer on the arduino is S201 ?

I'll change this china moisture fork with something stainless steel

[Fat Fly]

One question. This sketch measure moisture every 60000 ms, 10 min.It is possible to measure every 30 min ? Battery power lost is minimal.
If this fork in water domoticz reported 88% of moisture. How to change value?

[Fay Candiliari]

@Fat-Fly Hi there! This is Fay from codebender.cc Thank you for using codebender! I just wanted to let you know that the sketch you are using here has been deleted and so it is not available for users to view it. Let me know if you have any question!
Cheers!
Fay

@Fay Candiliari good morning.
I copied this scketch to my comp and delete all mysensors libraries and install development. After this all in ok.

[clivec]

Thought I would throw this in the pot
Why not change the sensor Probe ?? no credit to me , just was googleing as you do,
Home made sensors I think less prone to corrosion
here's the link

Had some seeds from very tasty tomatoes last year ,have planted and this year growing like tiffids !!
Getting quite big so have move from kitchen to Greenhouse ASP really
Will try with this type of sensor

[mfalkvidd]

@mutantx nice idea, thanks for sharing!

[Fat Fly]

I build moisture sensors from stainless wire. If this in pot at a depth of 1 inch domoticz reported 83% of moistre level.Real plant was dry and needed watering. I put moisture level on the soil

and sensor reported moisture level 43%. I test and put moisture sensor to the soil at depth 1 inch

Sensor reported moisture level 96%.

Hello,

After several weeks I finally succeed to create a dedicated PCB ! It was started yesterday evening and works fine.

Some pictures:

Measure is reported each two hours. So I expect more than two years on a CR2032 (using @GertSanders firmware).

I can off course provide any information as PCB.

Thanks @mfalkvidd for the idea and the code. The project is now WAF ;)

David.

[Fat Fly]

Great. Nothing to say. But i need build this. 10 pcs first time. :) I live in farm or how to right say in english. With rubber boots from the land ?

[Lukács Attila]

Is it possible to purchase it somewhere? :)

[Fat Fly]

Why not mastered it self ?

[Fat Fly]

Yesterday my sensor reported moisture 80% but soil was very wet. Thoughts.

[mfalkvidd]

@Fat-Fly that is normal. Did you expect something else? If so, what did you expect?

[flopp]

@Fat-Fly
I have sensors that report 25-35% and they are still not dry.
I water for 10-20 min and they report 40%, sometimes 45%. But I know that when they report 25% it starts to be time to water.

[mfalkvidd]

@flopp the level reported will depend on the following things (maybe more):

• the pullup resistor - varies between different arduinos
• the soil composition - varies between different pots
• the temperature - varies throughout the day

That means it is impossible to compare readings from two different Arduinos in the same pot and it is impossible to compare readings from different pots using the same Arduino.
