Story

INTRODUCTION

The project has four major objectives.

1]Fetch the latest sensor value from the bolt module.

2]Check if the value is greater than the limit.

3]If the value is greater it will send an SMS to the user.

4]Switch on the LED and will ring the buzzer.

CODE

Create a file name confy.py and save all the credentials related to Twilio . After that write the below code to save all the credentials.

confy.py

Now create one more file named wake_up.py .To do so type sudo nano wake_up.py in the terminal . Now we will write the main code to collect the data from the bolt and send SMS if sensor value is greater than the limit.

wake_up.py

OUTPUT

Since we have written a couple of print statement in the code. So the value will be printed on the code. if the value is greater then SMS will be sent to registered number. The screenshot of the sms is given below.

CODE

Python

First create a file name confy.py and then create another file name as wake_up.py then write the code .
We store all the credentials in a separate file since it is sensitive data which should not be shared with anyone.
In the main code we have import our conf file ,python json and time libraries are also imported.
Now to fetch the data from Bolt Cloud, we will create an object called 'mybolt' using which you can access the data on your Bolt.For the Bolt cloud to identify our device we will produce the API _KEY and DEVICE_ID.
To send SMS we will create an object .We have used the while loop to continue fetch the value and run the code. We have enclosed code in a try and except block.

Below is the code for the program.

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


limit = 300

my bolt = Bolt(confy.API_KEY,confy.DEVICE_ID)
sms = Sms(confy.SID,confy.AUTH_TOKEN,confy.TO_NUMBER,confy.FROM_NUMBER)
while True:
           print("Reading Sensor Value")
           response = mybolt.analaogRead('A0')
           data = json.loads(response)
           print("Sensor Value is: " +str(data['value']))
           try:
               sensor_value = int(data['value'])
               if sensor_value > limit :
                  print("Making a request to Twilio to send SMS")
                  response = sms.send_sms("Its Time To Wake Up.GOOD MORNING.Enjoy A Brand New Day")
                  print("Lets Switch On The Lights")
                  print("Switching On The Alarm")
                  mybolt.digitalWrite('1','HIGH')
                  print("Response received from Twilio is: "+str(response))
                  print("Status of the Sms at Twilio is: "+str(response.status))
               else:
                  print("Its Night")
                  print("Do Not Send The Message Through Twilio")
                  print("Do Not Turn On The Lights")
                  print("Do Not Turn On The Alarm")
                  mybolt.digitalWrite('1','LOW')
            except EXCEPTION as e:
                  print("Error occured.Below are the details")
                  print(e)
            time.sleep(10)
