Hi
I am a newbie to the raspberry pi world, but for the longest time I have wanted to make my own plant watering system. As an engineering student, I want to use this opportunity to learn more about how to hook up devices and use python to make my own flexible system. I have therefore not purchased the complete smart garden package, but rather couple of capacitive moisture sensors, «Pi2Grover Pi Hat» and «Grove 4 Channel 16 bit ADC».
I have used this tutorial www.switchdoc.com/2020/06/tutorial-capacitive-moisture-sensor-grove/ and gotten everything to work up until the part about generating percentage of the moisture readings. I struggle to understand where this code snippet goes and how to put in my moisture readings into it. I’ve tried to save it as its own script, but nothing happens when I run it by itself.
Code snippet in question:
Would love some guidance on how to proceed
Thanks,
Anzie

Code snippet in question:
# scale for capacitance sensor 1
def scaleMoistureCapacitance1(Moisture_Raw, PlantNumber):
# do the varying scale of the moisture for Capacitance readers
# do the varying scale of the moisture
# based on 10 bit values
# > #0 100%
# = #1 0%
# scale to 0% from there
#
if (Moisture_Raw < config.Capacitor1SensorCalibration[PlantNumber][1]):
Moisture_Humidity = 100
else:
Moisture_Humidity = ((config.Capacitor1SensorCalibration[PlantNumber][0] - Moisture_Raw)*100.0)/(config.Capacitor1SensorCalibration[PlantNumber][0] - config.Capacitor1SensorCalibration[PlantNumber][1])
if (Moisture_Humidity < 0):
Moisture_Humidity = 0.0
return Moisture_HumidityWould love some guidance on how to proceed
