HI TEAM,
I have coonected pi hat for raspberry pi with airquality analog sensor port A0 so i am using this program for it.i installed all packages but we can not get any output

This is the code for

Examples:
.. code-block:: python
import time
from grove.grove_air_quality_sensor_v1_3 import GroveAirQualitySensor
# connect to alalog pin 2(slot A2)
PIN = 2
sensor = GroveAirQualitySensor(pin)
print('Detecting ...')
while True:
value = sensor.value
if value > 100:
print("{}, High Pollution.".format(value))
else:
print("{}, Air Quality OK.".format(value))

Check whether I2C enabled and Grove Base Hat RPi or Grove Base Hat RPi Zero inserted
so how can we resolve this? please help me
