This is my first post here, I have been wondering if soil PH sensors are real or fake? An example is Soil Sensor. After reading through this post, these seem pretty useless. However the answers here talk about how USEFUL they are not if they give accurate readings. The thing that worries me about sensors such as these for being placed and left is mainly that it is ONLY reading from ONE place, and this isn't a good representation of the area as a whole.
I am wondering if anyone else has tried these? How accurate (if at all) are these? I am thinking of getting one and testing it against a Home Depot PH paper strip test.
Thanks for the info!
