Abstract — Robbery is a danger encountered several times. Modern electronics yields itself for robbery; also it shows ways to avoid it. We have, therefore, in this project, attempted to develop an integrated system that combines the features of a Embedded controller, GSM and IoT devices to be useful in detecting, monitoring and protecting through internet. The ultra modern micro electronics has made opportunities for the development of such security system with the advent of sensors for sensing the presence of a person. We use PIR sensor unit to detect the presence of any Person. Our system consists of three sections detecting, monitoring and protecting. Here detecting system consists of PIR sensor to indicate the motion of the human being. Smoke sensor to detect the smoke. Temperature sensor to sense the temperature variations. Vibration sensor to sense vibration level. Door breakage detector to detect the breaking of door to rob. Second section is monitoring, when the intruder enters into the monitoring area this sensor detect the intruder and immediately send the indication to the user through mail to reveal the message and also send the alert SMS to the user for notification. By this user can able to understand something has happened in his place and he can proceed for further action. Last section is protective section, it consists of spray control system which is controlled through internet to make the opponent unconscious for certain interval. Hence the electronic system which provides these three sections helps to prevent the properties from robbery and other unnecessary problem and also provides solution to the user to live a secured life.

I. INTRODUCTION

From last few year security is an essential requirement of armored cars, banks, houses, offices, etc., to keep properties safe from intruders to get rob. So the researchers and companies tries to implement an algorithms and make some gradates that keep your properties safe from intruders. This leads to advance technology that make your system intelligent or modern this called as intelligent security system also. With this technology property owner can control other appliances as well like lighting system, dimming, electrical appliances and many more. Now a day's wireless technology is used to control appliances instead of wired topological connection. GSM (Global System for Mobile Communication) technology makes used to communicate input signal from appliances to output message on device. That means after detection of any intrusion GSM Modem sends the appropriate message to owner's phone. The signals or data which is comes from sensors or other equipment digitize it by GSM module and send it to receiver. The user can control the rob by turn on spray unit to make robber unconsciousness through internet.

II. EXISTING SYSTEM

As the social computerization and automation has been increased and the ATM and credit card has been installed and spread out to simplify the activity for financial activity, the banking activity has been simplified, however the crime related with financial organization has been increased in proportion to the ratio of spread out of automation and devices.

POTENTIAL TRANSFORMER

The potential transformer works along the same principle of other transformers. It converts voltages from high to low. It will take the thousands of volts behind power transmission systems and step the voltage down to something that meters can handle. These transformers work for single and three phase systems, and are attached at a point where it is convenient to measure the voltage. CURRENT MEASURING CIRCUIT

The current drawn by the load is measured by using current transformer. The primary of the current transformer is connected in series with the load. A resistance of suitable value is connected across the secondary of the current transformer. Here the current is converted into voltage. Now the voltage drop across the resistor is applied to an attenuator circuit. The attenuator circuit reduces the voltage to a required level.

ARDUINO (ATMEGA 328) Arduino is an open-source computer hardware and software company, project and user community that designs and manufactures microcontroller-based kits for building digital devices and interactive objects that can sense and control objects in the physical world.





The project is based on microcontroller board designs, manufactured by several vendors, using various microcontrollers. These systems provide sets of digital and analog I/O pins that can be interfaced to various expansion boards ("shields") and other circuits. The boards feature serial communications interfaces, including USB on some models, for loading programs from personal computers. For programming the microcontrollers, the Arduino project provides an integrated development environment (IDE) based on the Processing project, which includes support for the C and C++ programming languages. The first Arduino was introduced in 2005, aiming to provide an inexpensive and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats, and motion detectors.

Arduino boards are available commercially in preassembled form, or as do-it-yourself kits. The hardware design specifications are openly available, allowing the Arduino boards to be manufactured by anyone. Industries estimated in mid-2011 that over 300,000 officials Arduino had been commercially produced, and in 2013 that 700,000 official boards were in users' hands.

RELAY DRIVER

ULN2003 is a high voltage and high current Darlington array IC. It contains seven open collector darlington pairs with common emitters. A darlington pair is an arrangement of two bipolar transistors. ULN2003 is for 5V TTL, CMOS logic devices. These ICs are used when driving a wide range of loads and are used as relay drivers, display drivers, line drivers etc. ULN2003 is also commonly used while driving Stepper Motors.

Each channel or darlington pair in ULN2003 is rated at 500mA and can withstand peak current of 600mA. RELAY Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically. They are very useful devices and allow one circuit to switch another one while they are completely separate. They are often used to interface an electronic circuit (working at a low voltage) to an electrical circuit which works at very high voltage. For example, a relay can make a 5V DC battery circuit to switch a 230V AC mains circuit. Thus a small sensor circuit can drive, say, a fan or an electric bulb. A relay switch can be divided into two parts: input and output. The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it.





This voltage is called the operating voltage. Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc. The output section consists of contactors which connect or disconnect mechanically.

In a basic relay there are three contactors: normally open (NO), normally closed (NC) and common (COM). At no input state, the COM is connected to NC. When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. Different relay configurations are available like SPST, SPDT, DPDT etc, which have different number of changeover contacts. By using proper combination of contactors, the electrical circuit can be switched on and off. Get inner details about structure of a relay switch.

LM35 TEMPERATURE SENSOR

LM35 Temperature sensor Pinout

The LM35 is an integrated circuit sensor that can be used to measure temperature with an electrical output proportional to the temperature (in °C).It can measure temperature more accurately than a using a Thermistor. The sensor circuitry is sealed and not subject to oxidation. The LM35 generates a higher output voltage than thermocouples and may not require that the output voltage be amplified. The LM35 has an output voltage that is proportional to the Celsius temperature. The scale factor is .01V/°C. The LM35 does not require any external calibration or trimming and maintains an accuracy of +/-0.4°C at room temperature and +/-0.8°C over a range of 0°C to +100°C.Another important characteristic of the LM35 is that it draws only 60 micro amps from its supply and possesses a low self-heating capability. The LM35 comes in many different packages such as TO-92 plastic transistor-like package,T0-46 metal can transistor-like package,8-lead surface mount SO-8 small outline package.

WORKING PRINCIPLE OF LM35

There are two transistors in the center of the drawing. One has ten times the emitter area of the other. This means it has one tenth of the current density, since the same current is going through both transistors. This causes a voltage across the resistor R1 that is proportional to the absolute temperature, and is almost linear across the range. The "almost" part is taken care of by a special circuit that straightens out the slightly curved graph of voltage versus temperature.





The amplifier at the top ensures that the voltage at the base of the left transistor (Q1) is proportional to absolute temperature (PTAT) by comparing the output of the two transistors. The amplifier at the right converts absolute temperature (measured in Kelvin) into either Fahrenheit or Celsius, depending on the part (LM34 or LM35).The little circle with the "i" in it is a constant current source circuit. The two resistors are calibrated in the factory to produce a highly accurate temperature sensor. The integrated circuit has many transistors in it -- two in the middle, some in each amplifier, some in the constant current source, and some in the curvature compensation circuit. All of that is fit into the tiny package with three leads.

HOW TO CONNECT TEMPERATURE SENSOR TO ARDUINO UNO?

The LM35 IC has 3 pins-2 for the power supply and one for the analog output. It is a low voltage IC which uses approximately +5VDC of power. The output pin provides an analog voltage output that is linearly proportional to the Celsius (centigrade) temperature. Pin 2 gives an output of 1 mill volt per 0.1°C (10mV per degree).So to get the degree value in Celsius, all that must be done is to take the voltage output and divide it by 10-this give out the value degrees in Celsius.

The circuit connections are made as follows:

Pin 1 of the LM35 goes into +5V of the arduino Pin 2 of the LM35 goes into analog pin A0 of the arduino Pin 3 of the LM35 goes into ground (GND) of the arduino

GSM MODEM

GSM MODEM is a class of wireless MODEM devices that are designed for communication of a computer with the GSM. It requires a SIM (Subscriber Identity Module) card just like mobile phones to activate communication with the network. Also they have IMEI (International Mobile Equipment Identity) number similar to mobile phones for their identification. The MODEM needs AT commands, for interacting with processor or controller, which are communicated through serial communication. These commands are sent by the controller/processor.





The MODEM sends back a result after it receives a command. Different AT commands supported by the MODEM can be sent by the processor/controller/computer to interact with the GSM cellular network. GSM MODEM SIM900

The GSM modem is a specific type of device, which accepts a SIM card operate on a subscriber’s mobile number over a network, as a cellular phone. Modem sim300 is triband GSM/GPRS locomotives that perform on EGSM900MHz, DCS1800MHz and PCS1900MHz frequencies. GSM Modem is used as a RS232-logic level compatible, i.e., it various from -3v to -15v as logic high and +3v to +15 as logic low.MAX232 is used to convert TTL into RS232 logic level converter is used between the microcontroller and the GSM board. The microcontroller signal is sent to the GSM modem through pin 11 of max232. The pin2 of the GSM modem received the signal from microcontroller. The GSM modem transmits the signals from pin3 to the microcontroller through MAX232.

FEATURES OF GSM Single supply voltage 3.2v-4.5v Typical power consumption in SLEEP Mode: 2.5mA. SIM300 tri-band Typical powerconsumptioninSLEEPMode: 2.5mA. SIM300tri-band MT, MO, CB, text and PDU mode, SMS storage: SIM card Supported SIM Card: 1.8V, 3V

LEVEL CONVERTER (MAX232)

The RS232 is not compatible with today’s microprocessors and microcontrollers; we need a line drive (voltage convertor) to convert the RS232’s signals to the TTL voltage levels that will be acceptable to the 8051’s TxD and RxD pins. The MAX232 converts from RS232 voltage levels to TTL voltage levels, and vice versa. One advantage of the MAX232 chip is that it uses a +5 V power source which is the same as the source voltage for the 8051. In other words, with a single +5 V power supply we can power both the 8051 and MAX232, with no need for the dual power supplies that are common in many older systems.
