Good product
Needed these sensors for a school project. Worked as expected and didn't need to calibrate them. Very happy with my purchase.

This is not for detecting water level in soil
I am taking a point off for the wrong indication, you do not want to put this into soil it will corrode. It would also need an AC circuit to make it not corrode which you would need to modify this circuit to support. It is much better as a leak or water detection device. This is what I am using it for, to detect water leaks, in my setup. The device will self destruct if you leave it in water for any length of time. It will plate out you can put some conformal coating on it to help it last a bit longer in water, in the end though it is not the right part for soil moisture detection as advertised. If you are looking for a soil moisture detector you are better off with a capacitive style sensor.

Soil Moisture Sensor Review
Work well they appear to be accurate great for the value not sure about the durability but will let you know later and easy to use

OK
This product is ok for use in student and hobby projects.For application as a soil moisture sensor for long periods of time, it is recommended to power the electronic module automatically to turn it on only when taking measurements, turning it off immediately when finished and thus minimize electrolytic corrosion. You can also swap the connections of the sensing element periodically so that the two electrodes rotate polarity.

Inconsistent baseline
Works well but the baseline value changes so much it’s tough setting the temperature range
H**Y
For prototyping only
These are beautifully cheap and they work great. Just don’t expect it to last more than a week in soil. More repeatable than I expected and dead simple to use with an arduino.

Not so accurate
I wont lie, the signal was very unreliable and caused my auto plant waterer to go haywire in sending water. The obscure moisture values depended on minerals from the soil i realized but its durable, just not super accurate. Also very easy to attach to arduino/clone!
