Story

According to a the FBI Uniform crime reporting statistics, there are 2.5 million Burglaries, and 66% of them are by house intrusions. There are 1, 495, 790 burglaries during the day. Break ins are 6% more likely to occur during the day between 6am and 6pm while people are at work or running errands.

By using the 3-Level intruder alert system we can avoid the burglaries and crimes caused by the intruders as a buzzer starts to beep so as to alert the surroundings and we get notified via SMS as well as Mail.

In the 3- Level Intruder Alert system, the LDR measures the Maximum Intensity of the Light when the door is closed as it becomes a closed circuit, but, when an Intruder tries to open the door it Open circuits the LED causing LOW intensity of light, When the low light is detected the Python program developed for this system alerts the surroundings, alerts the registered owner through SMS and Mail.

The buzzer stops beeping in 20 sec after closing the door.

Hardware setup

STEP 1:-Connect the LDR, one terminal to the A0 and other to the 3v3 pin of the Bolt wifi Module using jumper wires

STEP 2:- Connect 2 resistors of 330 ohm parallelly and then connect one end to the Ground and other to the A0 pin of the Bolt Module.

STEP 3:- Connect the Buzzer with negative end to the Ground and other to the 1 digital pin of bolt module.

STEP 4:- Take a pen barrel and cut half. Now, Insert the LDR at the one end inside such that the terminals come out. Insert the LED to the opposite end, so that when the LED glows the light emitted directly falls on the LDR and it detects maximum light intensity.

STEP 5:- Also wrap it with paper to prevent the surroundings light into the barrel.

STEP 6:- Now, Connect the negative end of LED to ground and positive end to an iron clip which is made to contact the metal scale that in turn is connected to the 0 digital pin of the module using a wire.(Note that the metal scale and clip acts as a switch of the LED circuit).

STEP 7:- Connect the USB cable to the bolt wi-fi Module for power.

(The circuit and schematic diagrams are attached below)

Software

STEP 1 :- Store all the necessary ids such as bolt API ID and credentials in a program. Create and generate APIs, Domain name, Authorized token from the apps like twilio and Mailgun which we use for Alerting the registered owner through sms and Mail respectively

STEP 2:- Import the program with ids and write the main code for the 3-Level Intruder Alert System.(The code is given below).

STEP 3:- Run the Program to turn the Intruder Alert system ON.

Conclusion

The 3- Level Intruder Alert system alerts in three different ways when an intruder is detected. It also Alerts the people in surroundings. The buzzer also stops beeping in 20 seconds after the door is closed.

Code

import keysandids, json, time#importing all the ids, json to load the content in json format
from boltiot import Email, Bolt, Sms#impoting bolt class, Email for sending mail and Sms for sending sms
mybolt = Bolt(keysandids.bolt_api_key, keysandids.bolt_device_id)#for bolt cloud to identify your device
isOn = myboly.isOnline()#to check the status of the system
print(isOn)
c = 0#this constant is used to turn off the buzzer
if isOn[-2] == '1':#isOn[-2] gives 1 if the system is online and 0 the other case
	print("Turning ON Intruder Alert System")
	mybolt.digitalWrite('0', 'HIGH')#to turn on the LED
	while True:
		if c >= 2:#to turn off the buzzer after 20 sec
			print("Turning Alarm OFF")
			mybolt.digitalWrite('1', 'LOW')
			c = 0
		elif c == 1:
			c = c + 1
		response = mybolt.analogRead('A0')#getting response from the bolt A0 pin
		data = json.loads(response)
		try:
			light_intensity = int(data['value'])
			if light_intensity < 1024:#if the LED is turned off
				c = c + 1
				print('Intruder Detected')
				print('Turning ON ALARM')
				mybolt.digitalWrite('1', 'HIGH')#turns on the buzzer
				print('Alerting through SMS and Mail')
				sms = Sms(keysandids.twilio_sid, keysandids.twilio_auth_token, keysandids.from_number)#passing the parameters required to send sms
				response = sms.send_sms("Alert!There's an Intruder in the house")#sends the msg as Alert! theres an Intruder in the house
				print('Status of SMS at twilio is '+ str(response.status))
				mailer = Email(keysandids.mailgun_api,keysandids.mailgun_domain_name,keysandids.sender_mail, keysandids.rec_mail)#passing the requiresd info to send mail
				response = mailer.send_email('Alert!',"there's an intruder in the house")#getting the response
				response_text =json.loads(response.text)#loading response json format
				print('Status of Mailgun is '+str(response_text))#printing the status of the mail
		except Exception as e:
			print('An Error Occured')
			print(e)
		time.sleep(10)
else:
	print('The Intruder Alert system is OFFLINE')
