HOME AUTOMATION BASED ON USER DETECTION USING INTERNET OF THINGS FIELDOFINVENTION
The present invention generally relates to a field of internet of things, and particularly to the field of home automation using internet of things.
BACKGROUND OF THE INVENTION
The technical advancements disclosed by the present invention overcomes the limitations and disadvantages of existing and convention systems and methods.
Home Automation system(HAS) using IoT is a system that uses computers or mobile devices to control basic home functions and features automatically through internet from anywhere around the world. An automated home is sometimes called a smart home. It is meant to save the electric power and human energy.
The electronic devices present inside and outside the home is controlled manually by the switches. While the user enters the house, the user first needs to unlock the door and then enter inside the house. While entering, the user finds the house to be dark and even hot during night and summer respectively. The user then manually turns on the lights and fans and thus finds it difficult to reach the switches to do the same.
While leaving the house, the user might sometimes forget to switch on the lights and fans and thus a lot of electricity gets wasted during this process. Though this wastage of electrical energy may not be significant for household, it can be significantly huge for a city, still higher for a state and enormously high wastage for the entire country.
Whereas in home automation, these devices are controlled automatically based on certain parameters that are fed by the user during initialization of the system.
In order to address this issue, there needs to be a system for automatically controlling the use of electricity by turning on the loads when the user enters the house and turns off the load during exit. The system is designed to save a lot of electrical energy and human effort.
The technical advancements disclosed by the present invention overcomes the limitations and disadvantages of existing and convention systems and methods.

The units for measurement temperature are RH (relative temperature), D/F PT (/frost point) & PPM (parts per million).
The light sensor is a passive device that convert "light energy" whether visible or in the infra-red parts of the spectrum into an electrical signal output. Light sensors are more commonly known as "Photoelectric Devices" or "Photo Sensors" because the convert light energy (photons) into electricity (electrons). The light sensor is a component usually available in smartphones, notebooks, other mobile devices, automotive displays and LCD TVs. It is a photodetector that is used to sense the amount of ambient light present in the atmosphere.
The infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. An Active infrared sensor both emit and detect infrared radiation. Active IR sensors have two parts: a light emitting diode (LED) and a receiver.
The sensors are most often used in a PIR-based motion detector. The sensor is used herein to detect the presence of the visitor or any other object present near the entrance.
The audio sensor or sound sensor is a device that has a thin piece of material called a diaphragm that vibrates when hit by sound waves (similar to how eardrum vibrates when hearing sound). The vibration of the diaphragm is converted by the sensor into an electrical signal that is sent to the LEGO brick, which knows that a sound has been heard. The audio sensor is used herein to capture the voice of the visitor in case the visitor leaves a voice message for identification near the entrance. The audio sensor is preferably a microphone.
The load is connected to the controller unit. The load includes the electrical appliances such as a lighting module, a cooling module, a heating module or other such modules present in the house. The load includes the plurality of switches connected to each module. The switches are controlled by the command signals received from the controller unit. The command signals received from the controller either switches on or off the load automatically based on the requirement of the user.
The system includes a plurality of curtains or blinds positioned at each of the windows. The blind is a thin sheet that acts as a covering on the windows in order to block the passage of light from entering the house through the glass panes of the window. The blinds are connected to a motor unit. When the atmospheric light becomes sufficiently less during the day time, the blinds are automatically rolled up based on the command signals received from the controller and the light sensor.

Generating command signals by a controller unit interconnected with the plurality of sensors and a load via a motor and a plurality of switches, wherein the controller unit activates the load when the presence of a person is detected near the entrance of the house via the infrared sensors, wherein the motor is connected with a blind or curtain receives the command signals to either rotate in clockwise or anti-clockwise direction in order to fold or unfold the curtain or blind to allow the sunlight enter inside the house.
Activating a cooling module connected to the controller unit via the plurality of switches, wherein the cooling module is activated when the temperature present inside the house exceeds beyond 25 deg Celsius in order to maintain the temperature inside the house.
Activating a lighting module connected to the controller unit via the plurality of switches, wherein the lighting module is activated when the sunlight is not sufficient enough to brighten the house, wherein the lighting module is switched on to brighten of the house.
According to an embodiment of the present disclosure, the system includes a plurality of sensors for capturing an image of a visitor, an audio sensor for receiving the voice message of the visitor, a temperature sensor for measuring the temperature inside the house, an IR sensor for detecting the presence of a person present inside the house. The data acquired from the plurality of sensors are stored in the database and sent to a controller unit. The controller unit is interconnected to the plurality of sensors and receives the images of the visitor, the audio of the visitor, the fingerprint of the visitor, the temperature and the lighting conditions of the surrounding. The controller unit includes a processing module for processing the signals obtained from each of the sensors. Further, the controller includes a matching and comparator circuit.
The controller unit is able to compare the processed signals through the comparator circuit that compares each of the signals from the sensors and with a predefined threshold value and generates a command signal which is either a '0' or '1' based on the value obtained upon comparison. The ON state/ HIGH state is designated as 1 and the OFF state/ LOW state is designated as 0. The controller is designed to run one specific program and is dedicated to a single task. The controller units are low power devices with dedicated input devices and small LED or LCD display outputs. The controller unit either includes a Arduino UNO, or a Arduino Nano or a Arduino Mega or other similar devices based on the requirement of the system.
The communication module is interconnected with the controller unit and the user's interface device. The communication module transmits the signals from the controller unit to the user's device through a wireless medium such as Bluetooth, ZIGBEE and other such mediums known in the art. The communication module is able to send visitor image along with an audio message to the user device for manual authentication of the visitor in case the visitor is not identified by the system.
The database associated with the system holds the real time data of the image of the face for frequent visitors, the fingerprint of the visitor for additional security along with the image of the face, the light conditions and the temperature of the surroundings. The matcher and the comparator circuit compare the sequence of data and matches with the threshold value. If the real-time values received from any of the sensors, a control signal is generated by the controller unit. The control unit is further connected to a plurality of sub-controlling units associated with each load.
The image of the visitor standing at the entrance is captured by the camera. The image is compared with the images stored in the database, if the image does not match with the images stored in the database, the controller unit sends the signals to the locking unit attached at the entrance. The locking unit at the entrance keeps the door locked until the visitor gets identified. Further, the image of the visitor is sent to the user's device for manual recognition and the system activates the audio sensor to record the audio message of few seconds, in case the visitor wants to convey audio message for the user. If the visitor gets identified at the entrance, the door unlocks and the visitor is allowed to enter the house.
Meanwhile, the load present inside the house is connected to the controller unit via the plurality of switches. If the temperature/temperature data collected by the temperature sensor from outside the house of the user increases beyond a threshold value, the controller sends the command signals to the switches associated with the cooling appliances. The cooling appliance gets turned on and maintains the temperature inside the house. The user gets a desired temperature inside the house on arrival.
The lighting conditions of the house is adjusted based on the atmospheric lights. The atmospheric light is sensed by each of the light sensors embedded near each of the windows of the house. When the user enters during the day time i.e. from morning hours till afternoon, the atmospheric light is sufficient enough to brighten up the room and saves energy. The controller unit sends the control signals to the motor associated with the curtains or the blinds to unfold itself and let the lights enter the house. In case, the user enters the room during evening, night or when the atmospheric light is not sufficient, the light module present inside the house is switched on by the controlling unit automatically.
The user device comprises of a user interface module. The user is able to view the face of the visitor and manually authenticate the entry upon recognition through the user interface. The user manually feeds the data in the database regarding the name and image of the visitor through the user interface module.
The system is connected to the user's device wirelessly through the communication module. The communication module is either a wired or a wireless medium. The wireless medium includes either a Bluetooth, ZigBee, RFID, etc.
According to an embodiment of the present disclosure, the image of a visitor standing near the entrance is being captured by an image sensor/camera. The credentials about the visitor and the user are fed into the database. The images are then sent to a controlling unit where the images are being processed and matched with the images stored in the database. The real time images undergo image comparison with the images stored in the database using a matcher and comparator circuit. If the image of the existing user is found in the database, the user gets identified by the system and the entry of the user is authenticated inside the house.
The command signals are sent to a locking unit for unlocking the doors to allow the entry of the visitor inside the house of the user upon successful verification. When the user is not verified the image of the user along with an audio message is sent to a user device for manual verification. The user manually enters the name of the user upon identifying the name of the visitor in the database through a user interface device.
The locking device receives a command signal from the controller unit for unlocking the entrance door and allows the visitor to enter the house. If the user tries to enter the house without successful authentication, the controller unit sends a command signal to an alert unit and an alert signal in the form of a sound wave is generated by the alert unit.
According to an aspect of the present disclosure, the system uses a plurality of sensors such as an infrared sensor, a temperature sensor, and a light sensor. The infrared sensors are embedded near an entrance and senses the presence of a person entering inside the house. The temperature sensor is mounted inside the house of a user to measure the temperature in the house.
