Thanks for sharing.
Please can you point to the android app you are using?
HI ahmadordi! Nice way of showing the time without a RTC. Well done:-)
I tried your code with mine Soil sensor but I see the reads continuously fluctuating.
Did you have the same problem?
I see that after some mins it becomes more stable but not completely.
Under which limit can the soil be considered dry and needs water?
Thanks for your sharing.
