I've heard that the two-legged probe/sensor usually breaks after just a few days of use because the metal strip corrodes quickly. It is true? if it is true I have to buy many two-gauge probes/sensors and change them every time they break or I can use the "operational control module" circuit that alwais come with connected to a handmade probe/sensor with two copper strips of the same size connected in the same way to the operational control module? thank you so much, great video!

Maybe a bit longer but quick enough. I use nails, depends on how thick they are, but even ones that were 2 mm, lasted me for several seasons. Other things you can do is: only run electricity throughthem when you are actually measuring or use carbon probes

@@Ed19601 two legged moisture sensors are useless at best. They Never give the right moisture percentage. I think capacitance based are the way to go.

the moisture sensor you compare to costs 1,14 euro. So you made yours for 1,1 cent? I sincerely doubt that

Das Wasser hat ein Elektrisches Feld und das kann dann mein Sensor mit seiner Wünschelrute erfassen? Der Boden verändert durch Feuchtigkeit (aber ggF auch durch Dünger etc) seine Leitfähigkeit und damit seine Qualität als Dielektrikum. Das Beeinflusst dann die Kapazität des Kondensators (dessen Elektrisches Feld durch den Aufbau möglichst viel Erde durchdringt). Eigentlich sollte der Sensor in einer Düngerlösung entsprechend "feuchter" sein als in Leitungswasser als in Regenwasser als in Destilliertem Wasser... Vermutlich in der Praxis wenig relevant, aber es wäre interessant die Response aufs Gießen auszuwerten - ggF kann damit auch der Düngerbedarf bestimmt werden.

Klasse! Ich bewässere schon seit 20 Jahren automatisch, verwende Sensoren aus Edelstahl mit Widerstandsmessung, aber das ist zu ungenau, das Ergebnis hängt auch vom Versalzungsgrad des Substrates ab und zwischen den Elektroden wirkt auch ein elektrisches Potential vom Substrat her. Dadurch muss ich regelmäßig kontrollieren und nachjustieren. Ich denke ich werde Deine Lösung übernehmen. Allerdings werde ich auch versuchen, kleinere Sensoren für die kleinen Töpfe zu bauen. Vielen Dank jedenfalls!

Hi, muss der Sensor denn auch so lang sein oder kann man ihn beispielsweise auch halbieren?

The way I see it, he made a part that shows as water rises inside, the sensor than shows that there is more water. Than as the water lowers, the sensors shows less. That's not going to work in a medium, the water is all around and it gets drained by the roots, the sensor will be wet 100% for a few seconds and than dry a minute after since the water wont be touching it anymore. This is not going to work since the water isn't going to rise and fall like its being dipped into a cup of water.

This sensor detects the moisture level of any substance it is inside of. Yes of course the sensor will eventually detect a peak the second you water it, but any substrate eg. dirt or even coconut will retain water. And to track this time while the substrate dries slowly is the main purpose of the sensor.

I had a look into the AT328 datasheet and based on the Arduino code from github, still can not figure out what is the frequency of the PWM and what it means for duty cycle of 2 (it is a comment in the code). On Wikipedia en.wikipedia.org/wiki/Duty_cycle it is measured from 0 to 1 (ratio from the frequency). Can you help on this? And the second question: is a way that you can calculate the frequency and the duty cycle? Thanks!
@GermanMythbuster

Duty cycle goes from 0 to 255, so 128 for example is 50% on then 50% off. So basically a ratio of off to on in 256 increments. PWM frequency is 490 Hz (default) but can go up to 62.5 KHz if you change some registers. TCCR0A and TCCR0B TCCR1A and TCCR1B TCCR2A and TCCR2B depending on the PWM pin used
