Move-inator

People, especially engineers, are at their desks for many hours. My idea is to help them move out of their chairs and make 'em active.

•The Bolt IoT module returns the sensor value every five minutes only.
•The maximum sitting time can be set by the user depending on their requirements.
•I have assumed that the person is sitting only when he is resting his back on the back-rest. (Sensor is placed there. If the sensor were placed anywhere else, it might get damaged.
import conf
from boltiot import Sms, Bolt
import json, time

mybolt = Bolt(conf.API_KEY, conf.DEVICE_ID)
sms = Sms(conf.SSID, conf.AUTH_TOKEN, conf.TO_NUMBER, conf.FROM_NUMBER)
flag = 0;

while True: 
    response = mybolt.analogRead('A0') 
    data = json.loads(response); 
    print (data['value']);
    try: 
        sensor_value = int(data['value']) #storing sensor value in a variable
        print (sensor_value)
        if sensor_value > 0:
          flag++; # flag value gets incremented every five minutes when the sensor returns a non-zero value.
          if flag>5 
            response = sms.send_sms("You have been sitting for a long time. Time to get up!! ")
          
            
    except Exception as e: 
        print ("Error",e)
    time.sleep(10)
