Story

Application in home automation

You can basically keep this in your room at suitable point and can put the resistor of required value according to your room lighting. You can also attach your lamps to this hardware thus if external light is too low lamp will have greater brightness, and when there is more light in your room the lamp automatically goes to minimum brightness. Thereby maintaining sufficient lighting in your room.

Here in this picture you can see that the external light is somewhat less so that led has turned on and has set accordingly.

Here you can see there is actually more light in the room so there is no requirement of led to be turned on and it has so happened.

Application in the pharmaceutical company

There are certain pharma companies where chemicals and medicines are stored in dark room so that there is no chemical reaction due to light taking place and thereby maintaining the quality of product. If we keep this device in the dark room and if there is some light falling in the room we can get automatically get an alert message by the Twilio that the light intensity in the room is very high.

Code

SID = 'You can find SID in your Twilio Dashboard' 
AUTH_TOKEN = 'You can find  on your Twilio Dashboard' 
FROM_NUMBER = 'This is the no. generated by Twilio. You can find this on your Twilio Dashboard'
TO_NUMBER = 'This is your number. Make sure you are adding +91 in beginning'
API_KEY = 'This is your Bolt Cloud accout API key'
DEVICE_ID = 'This is the ID of your Bolt device'

import temp_sms
from boltiot import Sms, Bolt
import json, time

max = 300
 


mybolt = Bolt(temp_sms.API_KEY, temp_sms.DEVICE_ID)
sms = Sms(temp_sms.SID, temp_sms.AUTH_TOKEN, temp_sms.TO_NUMBER, temp_sms.FROM_NUMBER)


while True: 
    print ("Reading the sensor value")
    response = mybolt.analogRead('A0') 
    data = json.loads(response) 
    print("The current sensor value is: " + str(data['value']))
    try: 
        sensor_value = int(data['value']) 
        if sensor_value > max:
            print("Making request send a SMS")
            response = sms.send_sms("Light intensity in the rrom is very high. The Current sensor value is " +str(sensor_value))
            print("Response received from Twilio is: " + str(response))
            print("Status of SMS at Twilio is :" + str(response.status))
    except Exception as e: 
        print ("Error occured: Below are the details")
        print (e)
    time.sleep(10)
