I'd like to create a low-power, battery driven soil moisture sensor (I'm already using many battery powered mysensor nodes)
and wonder what would be better:
I2C - not sure about the deep sleep consumption here
Analog (Standard Aliexpress Sensor, found a power consumption spec on this page)
Does anyone have experience with these? I'm not sure if they can be easily turned off when sleeping e.g. if I connect them to
a digital out and switch it?
What would you use?
Thanks a lot!
