Story

Fire alarm system basically help each and every person. It help them to understand if there is any fire situation on any floor. In industries, offices, houses, hotels, hospitals, etc.So people can easily leave the place before fire increase. It will keep the people safe from danger.

Step No : 01

Step all Hardware Component

01. Bolt Module

02.Jumper Wire

03. USB Cable

04. LM35 sensor(Temperature Sensor)

05.Buzzer

Step No.02

Hardware Connection

01. Place Buzzer and LM35 sensor on breadborad

02.Buzzer Positive (+) is join by Green Wire to '0' port of Bolt Module

03.Buzzer Negative (-) is ground with LM35 sensor with Blue Wire

04. LM35 has three pin VCC, Output, GND

05. LM35 VCC is connected to Bolt Module to '5' port by Brown Wire

06. LM35 Output is connected to Bolt Module to 'A0' port by Orange Wire

07. LM35 GND is connected to Bolt Module to 'GND' port by Red Wire

Step No:03

01. First of we have to start Ubuntu service from Virtual Box.

02. Than Login to Ubuntu Server.

03. Than use ' sudo apt get update 'code.

04. Than unblock your api-key and put api-key with device-id from Bolt Cloud.

1 / 2

05. Than use ' sudo nano ' code with any file name with proper extension.

06. Than start write the code.

07. Save the file by using ' control x ' and 'Y' command to save file

08. Than check the result.

Code

Fire Alarm System

from boltiot import Bolt
import json
import time

api_key = "####################################"
device_id ="BOLT########"

minimum_limit = 300
maximum_limit = 350

mybolt = Bolt(api_key,device_id)

while True :
    print("Reading Sensor Value....")
    response = mybolt.analogRead('AO')
    data = json.loads(response)
    print("Sensor value is " + str(data['value']))
    sensor_value = int(data['value'])
    if sensor_value > minimum_limit:
       print(mybolt.digitalWrite('0','HIGH'))
    if sensor_value < minimum_limit:
       print(mybolt.digitalWrite('0','LOW'))
else:
       print("Error Occurred:   ")
       print(e)
time.sleep(2)
