Example code is out of date/wrong

[Reddy Kilowatt]

Hi,

this code

from purpleair.network import SensorList
p = SensorList()  # Initialized 11,220 sensors!
print(len(p.useful_sensors))  # 10047, List of sensors with no defects

should be

from purpleair.network import SensorList
p = SensorList()  # Initialized 11,220 sensors!
print(len(p.all_sensors))
