II.SYSTEM OVERVIEW
I.INTRODUCTION
Interactive online data acquisition and
control system plays a major role in the rapid
development of the rapid popularization and control
in the field of measurement and control systems. It
has been designed with the help of is that it makes the
system more complicated and not many reliable
electrical, electronics and low voltage equipment.
This makes the system more reliable and prevents
complication. It is the great demand in many
consumer applications and industries. This system
replaces several complex cable used for data
acquisition and use Atmega168 Arduino processor
and the data acquisition and control. Data acquisition
system is widely used in a number of automatic test
and measurement equipment. They are used to collect
the necessary data from input peripheral devices,
such as meters, sensors, etc.
This data acquisition system uses a 10-bit
ADC fast available ATmega168 AVR. The
ATmega168 has 16K bytes of Flash Program, 512
bytes of EEPROM and 1K byte SRAM. This system
can measure all kinds of electrical and non-electrical
signals locally and remotely. And be able to control

Figure shows the overview of IDAC system. Every
client can access the industry directly without any
interaction using internet. IDACS shows Intelligent
Data Acquisition and Control System. This system
contains single atmega168 processor which is
programmed. Atmega168 processor is the heart of
this work.
It handles two modes at the same time, DAC and
internet modes. During DAC mode Processor can
measure signals which are coming from various
external sources and applications. And it can be used
to control the industry machineries by the control
instruction sent by client via internet. Client can
interact the industry by giving instruction on his own
system using internet.
During signal measurements Analog to digital
converter is very important, because almost every
external source is giving analog signal only. This
system has an inbuilt 10-bit ADC with 6 –analogue
input channels.

16K bytes of Flash Program, 512 bytes EEPROM
and 1K byte SRAM. This system can measure any
kind of electrical and non-electrical signals locally as
well as remotely. And it can able to control the
devices remotely. The measured data can be
displayed on flash magic using serial to Ethernet

1. Arduino:
An Arduino is a tiny computer that can be
programmed to process the inputs and outputs that go
to and from the chip. Arduino is what is known as a
physical computing platform or incorporated, which
means that it is an interactive system using hardware
and software can interact with its environment. The
Arduino can be used to develop independent
interactive objects or can be connected to a computer
to retrieve or send data to the Arduino and then act on
that data (eg, sensor data sent to the Internet).
Arduino is an Atmel AVR microprocessor, a crystal
or oscillator (basically a raw clock time that sends
pulses to the microcontroller in order to operate at the
correct rate) and a 5V linear regulator. Depending on
type of Arduino you have, you might have a USB
connector so it can be connected to a PC or Mac to
upload or retrieve data. The Board sets the
microcontroller pins I / S (input / output) to allow
connection of the pins to other circuits or sensors.
2. Atmega168:
The Atmel ATmega168 is a low-power
CMOS 8-bit microcontroller based on the AVR
enhanced RISC architecture. By executing powerful
set of instructions in single clock cycle, the
ATmega168 gains throughputs approaching 1 MIPS
per MHz allowing the system designer to optimize
power consumption versus processing speed. AVR
core combines a large instruction set with 32 registers
of general purpose work. All 32 registers are directly
connected to the arithmetic logic unit (ALU),
allowing two independent registers to access in a
single instruction executed in one clock cycle.
Features:
 High pursuance with low power
consumption Atmel AVR 8-bit
microcontroller..
 It has Advanced RISC architecture.
 16 Kb of inbuild system-self-programmable
flash program memory
 512 bytes EEPROM

they use thermistors (temperature sensitive
resistors).
How it look like:
3. Analog to Digital Converter:
The Atmel ATmega168 features a
successive approximation 10-bit ADC. The ADC is
connected to an 8 channel analog multiplexer which
allows eight voltage inputs one constructed from
terminal pins of port C. Unipolar voltage inputs refer
to 0V (GND). The ADC contains a sample and hold
circuit which ensures that the input voltage to the
ADC is maintained at a constant level during the
conversion. The data acquisition system presented
uses two analog inputs, one of which can be used to
detect the temperature and the other can be used to
detect pressure. The system can be easily adopted for
additional analog inputs.
4. RS-232 Communication:
RS-232 (Recommended standard-232) is a
standard interface approved by the Electronic
Industries Association (EIA) for connecting serial
devices. RS-232 is a long established standard that
describes the physical interface and protocol for
relatively low-speed serial data communication
between computers and related devices. RS-232 is
the interface that your computer uses to talk to and
exchange data with your modem and other serial
devices. The serial ports on most of the computers
use a subset of the RS-232C standard.
IV. LM35 TEMPERATURE SENSOR
The sensor LM35 is an integrated circuit that can be
used to measure temperature with an electrical output
proportional to the temperature (in ° C).
Fig: Lm35 Temperature Sensor
V.PRESSURE SENSOR
The pressure varies smoothly from the surface of
the earth to the top of the mesosphere. Despite
pressure changes over time, NASA has averaged
the conditions for all parts of the world
throughout the year. As altitude increases,
atmospheric pressure decreases. One can
calculate the atmospheric pressure at a given
altitude. Temperature and humidity also affect
the atmospheric pressure, and it is necessary to
know these to calculate an accurate figure. The
graph on the right was developed for a
temperature of 15 ° C and a relative humidity of
0%.
Features:
• Development of Industry's Smallest and
Thinnest Class Piezoresistive Type Pressure
Sensors
• Industry's small and thinnest class.
• High resolution of 0.01kPa
Features:
 You can measure temperature accurately
than a using a thermistor.
 The sensor circuitry is totally sealed and not
subject to oxidation, etc.
 The LM35 generates a high output voltage
than thermocouples and may not require
that the output voltage be amplified.
 These sensors use a solid-state technique to
determine the temperature. That is to say,
they don’t use mercury (like old
thermometers), bimetallic strips (like in
some home thermometers or stoves), nor do

VI.PROXIMITY SENSOR
A proximity sensor is a sensor
capable of detecting the presence of nearby
objects without any physical proximity
sensor
contact.A
often
emits
an
electromagnetic field, or a beam of
electromagnetic radiation (infrared, for
example), and look for changes in the field
or return signal. The object being sensed is
known as the proximity sensor target often.
Different proximity sensor targets require
different sensors. For eg a capacitive
photoelectric sensor might be suitable for a
plastic target; inductive proximity sensor
always requires a maximum distance run
this metal that this sensor can detect is
defined "nominal range". Some sensors have
adjustments of nominal range or means to
report
a
graduated
detection
distance.Proximity sensors will have a high
reliability and long life due to the absence of
mechanical parts and lack of physical
contact between the sensor and the object
detected.
