2. 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

3. 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.

4.  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.

6. 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.

7.  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.

11. 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

12. 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

13. 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

14. 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

15. 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

16. 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

17. 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 intensity
