OBJECTIVES

To save Electrical Energy Consumption i.e. Minimize in

Electrical energy bill.

To provide security as well as monitor the Activities inside the

office via IP Web Cam.

Automatically Air freshening With Time interval

INTRODUCTION

Sometimes all peoples go out of the room but still fan light and

running, this is waste of energy, that need to be minimized..

Main door automatically close/open with counting incoming/outgoing

persons. i.e. it is very useful where air condoning is installed. It causes

proper use of Air conditioning system.

Boss’s(Head ) Room is Lock/Unlock Via-Bluetooth App using desired

character i.e. Password.

IP web cam App is used to monitor activities safely and

remotely access. Old android mobile set can be used ,so reduced

cost of installation CCTV.

Auto detection of darkness of environment. It also save

electrical energy consumption. This type of system can be used

in street light system.

METHODOLOGY

One Slide door is control by PLC . Two photo sensor is used

detect person ,then open door after 3 sec close automatically.

Another door via Bluetooth –Arduino. Bluetooth app is user

defined so it is security system.

Auto Air Freshener is run by Arduino. It uses timer in Arduino

as required time interval. Also it is user defined.

Darkness of environment senses by LDR sensor. Then Light is

controlled according to Darkness.

Activities monitor through IP Cam App on PC. It uses ip address

according to IP web cam App. So it is used in Wi-Fi as well as Hot Spot

tethering.

Counting is controlled by PLC & Photo sensor.it has special features

increment/decrement in counter until both sensor sense person.

Arduino

Arduino

An open-source electronics ATmega328P

platform based use hardware and software.

14 digital input/output pins , 6 analog

inputs, a 16 MHz quartz crystal.

Input voltage - 7-12V.

32k Flash Memory. Arduino Uno

Programmable Logic Controller

A digital computer used for automation of typically

industrial electromechanical processes.

Operate on AC/DC (115-240v).

8 inputs pin & 4 output with extension module.

Negligible probability of hanging of programme during

running

PLC LOGO

Bluetooth Module

Typical -80dBm sensitivity.

Low Power 1.8V Operation ,1.8 to 3.6V I/O.

Chipset CSR BC417143.

With integrated antenna.

HC-05

PHOTOELECTRIC SENSOR

Detect the distance, absence, or presence of an

object.

Assembled light transmitter, often infrared, and a

photoelectric receiver.

Four wires in Photo sensor.

PHOTOELECTRIC SENSOR

Solid state relay

An electronic switching device that switches ON or

OFF when a small external voltage is applied

across its control terminals.

It operate on the basis of electromagnetism.

It has e at least three pole two exciting & another

three NC,NO and COM.

6 V DC Relay

24 V DC Relay

DC MOTOR

A electrical machines that converts DC electrical

power into mechanical power. 6 V volts and is

controlled by the Arduino Microcontroller.

DC gear motor operates on 12 volts and is

controlled by the Arduino Microcontroller. It is 600 r.p.m. but due to gear output high power and

less r.p.m. DC MOTOR

LDR

Made up of semiconductor materials having

high resistance.

The electrons in the valence band of the

semiconductor material are excited to the

conduction band.

Resistance of LDR is inversely proportional

to the light intensityLDR connection diagram

CONCLUSION

The expected result from this project:

Automatically control of electric load.

By controlling the speed of fan and brightness of light as our demand

saving the electricity.

Highly secured dooring system.

Automatically water flowing control of basin.

Record the history by cc TV.

Making more comfortness and mentally satisfactions.

CONCLUSION

Using sensor device the speed of fan and brightness of light is controlled

By using Bluetooth apps highly secured door is constructed.

By using smart phone cc TV is developed.

Two rooms load is controlled by Arduino and PLC.

For some restriction automatically water control basin can not

developed. Further it can be developed

FUTURE RECOMMENDATION

Adding auto irrigation.

Water flow from basin tap can be stop/start

by detecting Hand.

Fan will be control by temperature sensor
