I use the sensor mentioned in the above link and the code is

import time
import grovepi
import atexit

atexit.register(grovepi.dust_sensor_dis)

print("Reading from the dust sensor")
grovepi.dust_sensor_en()
while True:
try:
[new_val,lowpulseoccupancy] = grovepi.dustSensorRead()
if new_val:
print(lowpulseoccupancy)
time.sleep(5)

except IOError:
print ("Error")
