'''
A somewhat fancier plantsensor based on cephir909's fancy plant sensor.
This sensor takes the value it gets when booting up and uses it as a baseline to measure moisture against.
You can change the step size of the capacity leds below, as in at what threshold the led triggers, some trial and error is needed to find best values
for different vessels/moisture levels/use cases.
