I plan on using the pi grow moisture sensors connected to a pi4 and not a pi zero. I also want to use more than 3 moisture sensors so I didn’t buy the pigrow hat for both the above reasons. On the product page it states that the sensors can be used without the pigrow hat.
Now my problem is the pinout doesn’t make any sense so I don’t know which of the 3 pins in the sht connecter is vdd, gnd and signal (I’m guessing signal is middle based on the pinout but lost with the others) can anyone help me?
I have one other question, can the sensors be plugged direct into the gpio pins and read? Or will I need to use an ADC? I can’t find if they are analog or digital sensors
