3. 1.INTRODUCTION TO THE PROBLEM
•Automation takes the complete control of total plants few authentication and manual
actions are needed from user side for completing action. Hence there is a must situation
for users presence at all times in the control for taking some timely needed control actions.
•The proposed system provides a good solution to this problem.
•The whole control room is environment is additionally implemented in the arm-android
platform and the same is communicated to the process through Bluetooth .
•Now the user in control can use mobile at anytime, anywhere to monitor and control the
whole plant.
•8051 is used here for acquiring from the process control parameters from the sensors like
temperature, gas etc and transmitting it via a Bluetooth module to an android device.
Hence the parameter values can be monitored and stored simultaneously.

4. •Data logging is a process in which a controller is used to collect the
process control parameters with the help of the sensors and analyse and
store the results for further analysis.
•SCADA system is a high end current control system which is implemented
in all major automation industries. Several works have been done for data
acquisition using 8051, A control engineer or a user must always monitor
to take an effective and timely control action.
•Wired technology – difficult to monitoring and long construction time.

9. •LM35 is an integrated circuit sensor
that can be used to measure
temperature with an electrical output
proportional to the temperature(in ºc)
•The LM35 does not require any
external calibration.
•An accuracy of +/-0.4 ºc at room
temperature and +/- 0.8 ºc over a
range of 0 to 100 ºc.
•When the temperature in the field
increases that the sensors senses it
and further operation takes place
TEMPERATURE
SENSOR
•LM35 is a precision IC temperature
sensor with its output proportional to
the temperature
•We can measure temperature more
accurately than a using thermistors.
The sensor circuitry is scaled and not
subject to oxidation.
•Possesses a low self-heating capability.
•The operating temperature range is
from -55ºc to 150ºc.

11. GAS
SENSOR
•A gas detector is a device that detects the
presence of gases in an area, often as part
of a safety system.
•Gas detector can be used to detect
combustible, flammable and toxic gases,
and oxygen depletion.
•Gas leak detection is the process of
identifying potentially hazardous gas leaks
by sensors
•Common sensors include infrared point
sensors, ultra sonic sensors, electrochemical
gas sensors, and semiconductor sensor.
FEATURES
•High sensitivity to LPG, Iso-butane,
propane
•Small sensitivity to alcohol and smoke
•Detection range 10-10000ppm
•Fast response time <10sec
•Simple drive circuit and long life
•Heater voltage: 5V

13. BLUETOOTH MODULE
• Bluetooth is a specification for the use of low-
power radio communications to link phones,
computers and other network devices over short
distances without wires
GENERAL SPECIFICATION
• Short range wireless connectivity.
• Low power consumption.
• Automatic recognition.
• Wireless signals transmitted with Bluetooth cover
short distances, typically up to 10 meters.
• Bluetooth devices generally communicate at less
than 1Mbps.
• Bluetooth networks feature a dynamic topology
called personal area network, up to 8 devices.

transistor arrays.
•It consists of seven NPN
Darlington pairs that features
high voltage output with
common cathode clamp diode for
switching inductive loads.
•The collector current rating of a
single Darlington pair is 500mA.

15. RELAY
•A relay is an electrically operated switch.
•In electromagnetic relays operating current flows through the
coil. when this operating current increases, coil energizes the
electromagnet.
•When the operating current becomes large, the magnetic field
produced by electromagnet is high such that this magnetic field
pulls the armature making the rip circuit contacts to close.
•The coil current can be ON or OFF so relay have two switch
positions and most have double throw switch contacts.
ADVANTAGES
•Relays can switch AC and DC systems for protection of ac and
dc components.
•Electromagnetic relays have fast operation and fast reset.
•Relays operating speeds which has the ability to operate in
milliseconds are also can be possible.
•They have the properties such as simple, robust, compact and
most reliable.

16. POWER SUPPLY
 The aim is to design the power supply section which converts 230V AC in to 5V DC.
 We short listed to use bridge rectifier, because half wave rectifier has less efficiency.
Even though the efficiency of full wave and bridge rectifier are the same, but as there is
no requirements for any negative for our application, we gone with bridge rectifier.

17. LIQUID
CRYSTAL
DISPLAY(LCD)
• LCD is an electronic device for
displaying text or characters.
We are using 16×2 LCD. It
represents 16 characters and 2
line display.
• LCD’s are economical and
easily programmable and can
easily display special and
custom characters.
APPLICATIONS
• The big shops and the shopping
centres use digital displays
now.
• Also, in trains and buses the
information like platform
