It works well

It is sometimes complex to operate other 'sensors' of this kind, but these are well documented on Utube and work well.

This probe is very good and easy to use

You can fight with other type of probe or go on utube and find how easy it to work with.

Plug and play

Very straightforward to use. Just now using it to check moisture before watering flowerbed.

good sensor

This product works well. It is expensive when compared with resistance soil moisture sensors. So far no signs of degradation with the capacitor based system while the resistance based systen suffers from electrolysis.

Would need more info

By buying this I thought that I would get a sensor that would deliver 0-3v, depending on ground moisture. I am currently using a competitor product that does just that but for a much higher price. When measuring the output, in the air and in the water, I never get the 0-3v range. I understand that this might be a calibration thing but then, if you want to use the sensor just with a relay board (no arduino, no programming). Just reading the voltage. Why don't I get that range ? How can I calibrate the sensor ? -------------------------------------------------------------------------------------------------------- We apologize for the issues you are having with your product.
