Story

At the end of the day the goals are simple : Safety and Security.

In our fast moving day to day life security is a very important part. It is very important to keep things safe and secure. Intruder alarm helps us to maintain this security.

This is a very simple yet efficient project made using LDR, LED and Bolt Wifi Module that gives us a notification via e-mail every time an intrusion is detected in the room.

WORKING :-

The Bolt IOT Wifi module is connected as shown in the circuit diagram. When the power supply is switched on, the LED starts glowing. As the light falls on the LDR its resistance is less. The resistance of a LDR decreases with increase in incident light. When there is an obstruction in between the light intensity reduces or cuts off. The LDR gives out an analog voltage . The greater the intensity of light falling on LDR, the greater is the corresponding voltage. Hence during any intrusion an obstruction is created thus reducing the output analog voltage. This is received by the 'A0' pin of the Bolt wifi module and is then monitored.

import json, time

mybolt = Bolt(email_conf.API_KEY,email_conf.DEVICE_ID) #Create object to fetch data from configuration file
mailer = Email(email_conf.MAILGUN_API_KEY,email_conf.SANDBOX_URL,email_conF.SENDER_EMAIL,email_conf.RECIPIENT_EMAIL) #Create object to send EMAIL

while True:
  print("Checking the status")
  response = mybolt.analogRead('A0')  #Fetching the value from BOLTIOT
  data = json.loads(response)
  
  try:
    v=int(data['value'])
    print(v)
    if v<200:
      print("Intrusion detected. Requesting to send email")
      response=mailer.send_email("ALERT","INTRUSION DETECTED")
      response_text=json.loads(response.text)
      print("MAILGUN response is :"+str(response_text['message']))
      
  except Exception as e:
    print("Error occured. The details are as follows")
    print(e)
    
  time.sleep(200)
