I bought a few of these moisture sensors -> https://cdn-learn.adafruit.com/downloads/pdf/adafruit-stemma-soil-sensor-i2c-capacitive-moisture-sensor.pdf?timestamp=1543968539
I have a few of them, so I need to change their I2C addresses in order to use all of them on the same Raspberry Pi.
The pdf I posted above says I need to short the AD0 or AD1 to increase the address by 1 or by 2.
What exactly does this mean?
Do I just need to apply a voltage to one of these to increase the address?
Is the required voltage 3.3V (same as Pi's logic level) or 5V?
How long does the voltage need to be applied for?
Does the sensor need to be connected to the Pi's 3.3V power supply while applying the voltage?
What happens if I go past the maximum address? Ex: I short AD0 until I reach 0x39 and then I short again? Should it reset to 0x36?
Thanks in advance!
