ABSTRACT : With the development of IoT (internet of things), the concept of smart device has become more and
more popular. Devices are connected to the internet and stretch their reach. Mobile phone is not only the common smart device. Smart watch, smart rings, smart TV, smart air monitor, smart sensors, all kinds of traditional devices turn to smart and have the capability to access the internet. There are platform designed to connect sensor data with users daily life. Although electronic appliances are becoming more intelligent day by day. Not only manufacturers are promoting new smart appliances; there are also many smartphone oriented remote controller products. Current products are having some platform compatibility problems in addition to those problems user interaction in such systems are also becoming more and more complex. Here the work proposed is an approach to enhance old appliances and the controlling experience through an IOT based Bidirectional visitor counter. Appliances are controlled using sensors. The sensor data are processed by single-board computer named Arduino Uno and delivered to mobile applications through wireless connection. The results of implementation and experimentation has shown the proposed system can provide more IoT application possibilities daily life.

I. INTRODUCTION
The main aim of this project is to minimize the power consumption with the help of Sensor module, LDR module. Nowadays, there are huge amount of electricity consumption in conference and seminar halls even when the people count is less. To overcome this quandary, this project gives the best solution by monitoring the count of number of persons inside the conference/seminar halls. Using IoT, according to number of visitors in a room, the lights and fans are controlled and automatically controls the lights based on the intensity of the room and if there is any fire accident it gives alarm and automatically blows up water into the fired place.
II. HARDWARE USED
A. ARDUINO UNO
The microcontroller used for this project is Arduino uno. The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet) is shown in the Fig:1. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller operations. It is connected it to a computer with a help of USB cable.
The Uno varies from other boards because it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.

Fig:2 Infrared Sensor INFRARED SENSOR
An infrared sensor is an electronic device that emits infrared radiation in order to sense some aspects of the surroundings. An IR sensor can measure the heat of an object as well as detects the motion. The radiations which are invisible to our eyes can also be detected by an infrared sensor. The emitter is simply an IR LED (Light Emitting Diode) as shown in the Fig:2 and the detector is simply an IR photodiode which is sensitive to IR light of the same wavelength as that emitted by the IR LED.
PIR SENSOR
FIRE SENSOR
Fire sensor is the most sensitive to ordinary light hence it is generally used for fire alarm purposes. The detection angle is 60 degrees when the fire level is especially sensitive.
C. LCD DISPLAY
A liquid crystal display (LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. Each pixel consists of a column of liquid crystal molecules suspended between two transparent electrodes, and two polarizing filters, the axes of polarity of which are perpendicular to each other. Without the liquid crystals between them, light passing through one would be blocked by the other. The liquid crystal twists the polarization of light entering one filter to allow it to pass through the other.
D. DC MOTOR
Fig:3 DC Motor
45 RPM 12V DC Motor as shown in the Fig:3 is any of a class of rotary electrical machines that converts direct current electrical power into mechanical power. The most common types rely on the forces produced by magnetic fields

instance, when the LDR is in darkness, then it can be used to turn ON a light or to turn OFF a light when it is in the light. A typical light dependent resistor has a resistance in the darkness of 1MOhm, and in the brightness a resistance of a couple of Kilo Ohm.
III. PROPOSED WORK
Fig:5 Block Diagram Of The Proposed Work This block diagram can be separated into three blocks,
Sensor block
Controller and Display block
Appliances block SENSOR BLOCK
The sensor block consists of IR sensor, PIR sensor, Fire sensor and LDR module. IR sensor is used to count the number of persons in the room. Fire sensor senses the occurrence of fire. LDR module monitors the intensity of the room.
CONTROLLER AND DISPLAY BLOCK
The Arduino board receives the messages from sensor block and controls the appliances in the room. Arduino switches ON the appliances based on number of persons in the room. LCD display is used to display the visitors count.
APPLIANCES BLOCK
BLOCK DIAGRAM EXPLANATION
In this proposed work, Arduino Uno controls the light and fan according to number of visitors in a room and automatically controls the lights based on the intensity of the room and if there is any fire accident it gives alarm and automatically blows up water into the fired place. The infrared sensor1 is employed to count the incoming visitors whereas infrared sensor2 is employed to count the outgoing visitors. So that the number of persons inside the room can be counted. The buzzer alarm as shown in Fig:5 is used for indicating the occurrence of fire. Two lights and two fans are employed in this project. If visitor count is 0, the two lights and two fans are at OFF state. If visitor count is in between the 1 to 5, one light and one fan is switched ON whereas another light and fan are at OFF state. Else all four appliances are in ON state. If visitors count goes more than 10 persons, message will be displayed in the LCD as no seats are available inside the room. If fire sensor detects the fire, it gives the information to the connected mobile numbers (no limit) and activates the buzzer alarm as well as water pump motor which automatically blows up the water into the fired place. IoT module collects the information about the visitors count and fire occurence.
IV. IoT MODULE
IoT module consist of sim card slot and antenna part. It is used to connect the Arduino Uno serial monitor information to the user’s sim card through the arduino uno transmitter and receiver pins. It sends the information about fire broke out to the customers phone number.
V. SOFTWARE USED
C Language
VI. CONCLUSION
From the concept of Bidirectional visitor counter, it is easy to minimize power consumption and also it is low in cost. Electricity usage is minimized by the automatic switching ON/OFF of lights and Fans based on visitor’s count. If any fire breakout, the system generates alarm and pumps up water automatically to reduce huge loss.
