python 3.x - Two sensors, Is it possible to pause a sensor for a short time? -

i have code saving data online. have 2 ir sensors reading door, 1 6 inches other. if first sensor goes off before second, know entering room, , code sends +1 file online. when second sensor triggered first, means leaving, system should pause , nothing should happen until person moves out of both sensors. last part isnt happening. how can pause first sensor when leaving, not accidentally double count?
code:

#!/usr/bin/python3.4  ubidots import apiclient  import rpi.gpio gpio import time import datetime import os import web  person_count = 0  ts = time.time() st = datetime.datetime.fromtimestamp(ts).strftime('%m-%d-%y  %i:%m:%s')  gpio.setmode(gpio.bcm) gpio.setup(4, gpio.in) #ir sensor closest door gpio.setup(25, gpio.in) #ir sensor farthest door gpio.setup(17, gpio.out) #led indicate when data being recorded web. api = apiclient("165c54954ee6d8f7324366495cab70217c7c3c91") test_variable = api.get_variable("559c18cc76254214be90fe05")  while true:     # if leaves, wait 1 second.     if gpio.input(4) == 0 , gpio.input(25) == 1:             gpio.output(17, false)             time.sleep(2)      # if both sensors blocked, wait 1 second until clear     elif gpio.input(4) == 1 , gpio.input(25) == 1:             gpio.output(17, false)             time.sleep(2)      # if neither sensor blocked, wait 0.1 seconds.     elif gpio.input(4) == 0 , gpio.input(25) == 0:             gpio.output(17, false)             time.sleep(0.1)      # if first sensor (4) blocked, send person count ubidots prog$   elif gpio.input(4) == 1 , gpio.input(25) == 0:             gpio.output(17, true)             person_count += 1             test_value = person_count             test_variable.save_value({'value':test_value})             time.sleep(1.5)
