    Safety and security frameworks are utilized to screen indoor conditions to furnish mortgage holders with live updates and cautions when hurtful circumstances may emerge while they are far away. The point of these frameworks is to decipher the tactile information gathered (through sensors) from the general climate to give cautions or to do some proper activities (through actuators) against undesirable occasions. For example, fire in homes could happen for various reasons, like the consuming of materials, gases, also, electrical circuits, which could cause genuine mishaps.

    To shield homes from fire, an alarm framework is an absolute necessity. Alarm frameworks are valuable in notice mortgage holders about this undesired circumstance and to forestall the

    deficiency of assets and human existence that could result from it.

    Gas spillage is another undesirable circumstance. Liquefied Petrol Gas (LPG) is the most broadly utilized gas for cooking in homes. It is given in chambers and may impact because of spillage. Much of the time, occupants don't realize that gas is spilling. They in this way may illuminate fire that causes an impact. To keep away from this perilous circumstance, a gas spillage recognition framework should be introduced and utilized.

    Crime is rampant these days as well. The establishment of safety frameworks in homes is hence essential. These frameworks can recognize developments that may happen because of a cheat going into a house. Furthermore, the client can handle the electrical apparatuses, for example, lights and fans and screen the house conditions from anyplace by utilizing cell phone, tablet or PC. As model, if the client has neglected to switch of the fan and he previously showed up at his office, he can turn off utilizing his smart gadget.

    To stay away from every one of the circumstances referenced above, fire, gas spillage, and movement discovery frameworks should be created what's more, utilized. Doing as such will guarantee the wellbeing and security of mortgage holders and their families and will keep them from genuine mishaps and undesired circumstances. Crafted by shrewd home wellbeing and security frameworks begins with checking the general climate and afterward responding to the previously mentioned unforeseen occurrences that may happen while mortgage holders are away by sending alert notices. What's more, some appropriate activities may likewise be taken by the frameworks, for example, halting fire through the splashing of water and decreasing the convergence of gas through air ventilation. The checking cycle of these frameworks is performed through sensors like temperature sensors, gas sensors, and movement sensors. In occasion of a crisis, these frameworks may send notices, for example, messages and messages. Also, they may utilize actuators like signals, lights, and screens to tell close by individuals. A correspondence medium is needed to communicate with these frameworks. Remote correspondence, for example, ESP8266 Wi-Fi module is broadly utilized in this unique situation. The study starts with characterizing a few exploration questions covering a few parts of this subject. Then, at that point, it recognizes the connected papers that ought to be analyzed to answer the distinguished inquiries.

      The problem statements that occurred in current situation/existing system are as follows:

      1. Security System-Numerous individuals are consistently progressing from one spot to another because of business requests. A few groups can put two or three days from their home leaving all their home devices with no sort of checking and control. A few gadgets are left connected to control attachments though others should be connected to and out of force attachments at various spans relying upon the time. This requires a person to physically go to every one of the gadgets freely occasionally. Indeed, even old and the disabled client dealt with issue to physically get to control of light and fan rather than robotization measure. A few gadgets if not

        controlled as expected devour a ton of energy which prompts additional consumption on power. So, all such checking and controlling of house hold appliances can be done. In our project, Automatic door open and close, Motion detection intruder alert and Controlling of home appliances like fan and light are performed.

      2. Disaster Detection-Disasters frequently occur nearby human work. More often than not, it is either regular (e.g., avalanche, tremor, wave, flood, woods fire, and lightning) or man-made (e.g., mechanical blast, spillage in an oil pipeline, spillage in gas creation, and psychological oppressor assaults). Notwithstanding the reason for episode, debacle prompts enormous obliteration as far as financial and living souls. In our project, we are detecting few dsasters such as Fire detection and Gas leakage detection.

It has 54 advanced info/yield pins (of which 14 can be utilized as PWM yields), 16 simple information sources, 4 UARTs (equipment sequential ports), a 16 MHz gem oscillator, a USB association, a force jack, an ICSP header, and a reset button. It contains all that expected to help the microcontroller; basically, associate it to a PC with a USB link or force it with an air conditioner to-DC connector or battery to begin.

Fig. 2: Home automation system architecture

Disaster detection includes gas leakage and fire detection and security system includes motion detection intruder alert, automatic door opening and closing, and controlling of few

home appliances like lights and fans. All the data obtained is sent to Arduino board. Here ESP8266 acts as communication channel between Arduino and Blynk app. Based on the data received from ESP8266, expected results are obtained in Blynk app.

  1. Disaster Detection

    1. Fire Detection- Fire recognition frameworks are regularly utilized in smart homes to guarantee home owner security and to keep away from or decrease property misfortune. On account of fire danger, these frameworks consequently advise property holders about this crisis circumstance and may play out some appropriate activities to decrease the effect. Normal reasons for fire could be gas spillage, cooking flare-ups, and electrical fire including electrical contactless, broken outlets, and defective machines. Here, IR based flame sensors is connected to pin 9 of Arduino board is utilized to identify fire. A flame-sensor is one kind of detector which is mainly designed for detecting as well as responding to the occurrence of a fire or flame. A furnace flame sensor works by detecting the presence of a flame within the furnace. At the point when fire begins in any space inside a home, the temperature of the encompassing air increments dramatically until arriving at a most extreme level, while moistness diminishes until arriving at any rate level or even zero. The sensor is a short length of thin metallic rod that creates a small current of electricity in order to confirm there is fire burning within the furnace. Range is 760 nm to 1100 nm (Light Wavelength).

    2. Gas Leakage Detection- LPG is a colorless, odorless fluid that promptly dissipates into a gas. Ordinarily, it is given in chambers, with odorants added to assist with identifying spills. LPG is a fundamental need of each family, as it is utilized for cooking and warming. Notwithstanding, its spillage could prompt catastrophes. At the point when the gas meets a wells spring of start, it can consume or detonate. Breathing in LPG fume at high fixations in any event, for a brief time frame can cause blacking out, suffocation, or potentially demise. Here, various gas sensors can be utilized to recognize the presence of gas in the climate. MQ2 Gas sensor is connected to pin Ao of Arduino board is utilized in our task. The gas touchy material utilized in the MQ2 gas sensor is SnO2 i.e., Tin oxide, a low electrically conductive material in clean air. When there is flammable gas in the encompassing air, the electrical conductivity of the sensor will increment with the higher power of the combustible gas. All gases contain some percentage of alcohol content in them. As, most hand sanitizers, whether you get them at the mall or at your local drugstore, will contain some kind of alcohol content in them. Using MQ2 sensor, we can detect combustible gas (Intensity 300~10000ppm and preheating time should be 2 minutes) and smoke detection.

  2. Security System

    1. Intrusion Detection-Intrusion detection systems are systems introduced in homes to caution owners and prevent undesirable circumstances, for example, house break-ins and violent crimes. Interruption can be distinguished by means of three location techniques, specifically, motion-based recognition, vibration-based identification, and picture-based

      discovery. In our project, we are showing motion-based detection.

      Motion-based detection-Here, motion sensors are used to detect intrusion. When there is a movement in any space inside a home, the pre-owned movement sensor will identify that development. To distinguish interruption by means of movement, various kinds of sensors can be utilized. The PIR sensor stands for Passive Infrared sensor is a low-cost sensor which can detect the presence of human beings or animal and is connected to pin 11 of Arduino board. It is an electronic sensor that detect general movement. PIR sensors are commonly used in security system. It can distinguish between object movement and human movement. It detects the infrared light emanated by a warm item. It comprises of pyro electric sensors which present changes in their temperature (because of episode infrared radiation) into electric sign. It covers a distance of about 7 meters.

    2. Lights and fans control- The client can physically turn on or off few home appliances like lights and fans using Blynk app. Even the client can use temperature sensors like DHT11 sensor which is a commonly used Temperature and Humidity sensor that can measure temperature from 0°C to 50°C and humidity from 20% to 90% with an accuracy of ±1°C and

      ±1% is connected to pin 6 of Arduino board. This sensor displays the temperature of the surrounding environment. Based on the temperature, fan will automatically turn ON/OFF. It is a commonly used Temperature and Humidity sensor that can measure temperature from 0°C to 50°C and humidity from 20% to 90% with an accuracy of ±1°C and

      ±1%. The client has the decision to adjust the room conditions dependent on the sensor readings (temperature, dampness, and so forth) like control the speed of the fan from the versatile application or the speed will be naturally changed dependent on the room temperature. By this way, the energy effectiveness can be improved in light of the fact that when the electrical machines are consequently or handily killed when not utilized, this will save more energy and reduction electrical bill cost.

      DC motor, Relay, External battery

    3. Door control-RFID(Radio Frequency Identification) tags are used for automatic door open or close. With RFID, remote programmed recognizable proof takes an unmistakable structure: the item, area, or individual is set apart with a remarkable identifier code as a hexadecimal number contained with the RFID tag, which is implanted in the RFID card. Mifare RC522 Module RFID Reader is utilized in our task. This module usually comes with a RFID card tag and key chain. The Reader can both read from and write to key cards or key rings. The tag reader creates a particular interrogation zone, inside which the tag can communicate with the reader. The reader also has a receiver that captures a reply signal from the tags, and decodes that signal. The key card and key ring that comes with the kit each contains a small embedded RFID chip. Every RFID chip has a unique serial number that identifies that particular key card. The RC522 RFID Reader module is designed to create a 13.56MHz electromagnetic field that it uses to communicate with the RFID tags. Both RFID reader module and RFID cards should share the same frequency range i.e., 13.56MHz. The main functionality of RFID tags is that they store a unique identifier that can be

read. RFID is useful to identify people, to make transactions, etc. We can use an RFID system to open a door. The RFID door lock system provides ease of implementation, and the RFID card cannot be duplicated. For example, only the person with the right information on his card is allowed to open the door. The angle at which the door has to be opened or closed is based on Servo motor which is connected to pin 12 of Arduino board. A Servo otor is a small device that has an output shaft. This shaft can be positioned to specific angular positions by sending servo a coded signal. As long as the coded signal exists on the input line, the servo will maintain the angular position of the shaft. If the coded signal changes, the angular position of the shaft changes. In our project, servo motor is used to rotate in an angle of 0 to 90 degree.


    Figure 3 shows the Implementation of the proposed work where all the sensors used in this system are mounted on the Arduino board. The outputs are obtained through the rotation of the servo motor where we can automatically control home doors, indication, and disaster detection can be shown through led on/off. The whole model results can be noticed in Blynk app which is shown in figure 4.

    Fig. 3: Implementation of the proposed system

    Fig. 4: Results shown in Blynk app

    Blynk app- Blynk is a web of things stage which permits controlling electronic gadgets distantly utilizing its iOS and android applications. It gives dashboard by which client can make realistic interface utilizing various gadgets. Blynk can likewise store and show sensor information. Blynk gives libraries to the greater part of the famous equipment stages like Arduino, ESP8266, Raspberry pi, Sparkle Fun and so forth In the Blynk three most significant segments are Application, Worker and Libraries. Application can assist with making the interface. Worker is liable for all the correspondence among application and the designs. Furthermore, Libraries empowers correspondence for equipment with the worker utilizing orders.
