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 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!

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 linkhttp://www.cheapvegetablegardener.com/how-to-make-cheap-soil-moisture-sensor-2/
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 -

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.

Is it possible to purchase it somewhere? :)

@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.@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.

This sort of sensor is not good, because the electrolyticeffect.
You always should use soil sensors, which are based on the capacitive effect.Like this one:
