title: How to convert the adc output of the capacitive soil humidity sensor v1.2 to actual humidity percentages in python(micropython)?
body: <p>Below is an example of a basic test code, from which you can read out the analog values of the sensor.
  However, higher values are where the driest places are. Strictly water approaches value of 0. This is contrary to my basic knowledge of how moisture/humidity works - more water in the soil/air - more moisture/humidity.
  What is the most efficient way to convert this into usable soil moisture percentages?</p>
  <pre class="lang-py prettyprint-override"><code>from machine import Pin, ADC
  from time import sleep
      
  soil_moisture = ADC(Pin(34))
  adc.width(ADC.WIDTH_12BIT)   # set 12 bit return values (returned range 0-4095)     
      
  while True:
    soil_moisture_value = soil_moisture.read()
    print(soil_moisture_value)
    sleep(2)
  </code></pre>
