13. LCD(liquid crystal display):
 Liquid Crystal Display (LCD) consists of rod-shaped tiny molecules sandwiched
between a flat piece of glass and an opaque substrate. These rod-shaped molecules
in between the plates align into two different physical positions based on the
electric charge applied to them.
 When electric charge is applied they align to block the light entering through them,
where as when no-charge is applied they become transparent.
 Light passing through makes the desired images appear. This is the basic concept
behind LCD displays.
 LCDs are most commonly used because of their advantages over other display
technologies. They are thin and flat and consume very small amount of power
compared to LED displays and cathode ray tubes (CRTs).
 LCDs have become very popular over recent years for information display in many
‘smart’ appliances. They are usually controlled by microcontrollers. They make
complicated equipment easier to operate.

19. A photoresistor or LIGHT DEPENDENT RESISTOR or cadmium
sulfide (CdS) cell is a resistor whose resistance decreases with
increasing incident light intensity. It can also be referred to as a
photoconductor.
ldr
A photoresistor is made of a high resistance semiconductor.
If light falling on the device is of high enough frequency
photonsabsorbed by the semiconductor give bound
electrons enough energy to jump into the conduction band.
The resulting free electron (and its hole partner) conduct
electricity, thereby lowering resistance.

20. Cont….
 A photoelectric device can be either intrinsic or extrinsic. An
intrinsic semiconductor has its own charge carriers and is not an
efficient semiconductor, e.g. silicon. In intrinsic devices the only
available electrons are in the valence band and hence the photon
must have enough energy to excite the electron across the entire
bandgap.
 Extrinsic devices have impurities, also called dopant, added whose
ground state energy is closer to the conduction band; since the
electrons do not have as far to jump, lower energy photons (i.e.,
longer wavelengths and lower frequencies) are sufficient to trigger
the device.
 If a sample of silicon has some of its atoms replaced by phosphorus
atoms (impurities), there will be extra electrons available for
conduction. This is an example of an extrinsic semiconductor.

21. Tempreture sensor:
• A thermistor is a type of resistor whose resistance varies with
temperature. The word is a portmanteau of thermal and resistor.
Thermistors are widely used as inrush current limiters, temperature
sensors, self-resetting overcurrent protectors, and self-regulating heating
elements.
• Thermistors differ from resistance temperature detectors (RTD) in that
the material used in a thermistor is generally a ceramic or polymer, while
RTDs use pure metals. The temperature response is also different; RTDs
are useful over larger temperature ranges, while thermistors typically
achieve a higher precision within a limited temperature range [usually −90
°C to 130 °C].
• Basic operation
•
• Thermistor symbol
• Assuming, as a first-order approximation, that the relationship between
resistance and temperature is linear, then:
• Where,
• ΔR = change in resistance
• ΔT = change in temperature
• k = first-order temperature coefficient of resistance

22. Rs-232

23. RS232:
In communications, RS-232 is a standard for serial binary data interconnection
between a DTE (Data terminal equipment) and a DCE (Data Circuit-terminating
Equipment). It is commonly used in computer serial ports.
Scope of the Standard:
The Electronic Industries Alliance (EIA) standard RS-232-C [3] as of 1969 defines:
• Electrical signal characteristics such as voltage levels, signaling rate, timing and slew-
rate of signals, voltage withstand level, short-circuit behavior, maximum stray
capacitance and cable length
• Interface mechanical characteristics, pluggable connectors and pin identification
• Functions of each circuit in the interface connector
• Standard subsets of interface circuits for selected telecom applications
The standard does not define such elements as character encoding (for example,
ASCII, Baud rate or EBCDIC), or the framing of characters in the data stream (bits per
character, start/stop bits, parity). The standard does not define protocols for error
detection or algorithms for data compression.

24. VISUAL BASIC
• Microsoft’s VB is perhaps the most successful attempt to provide a real higher level windows
programming language, which really uses the facilities of the environment for writing as well
as the executing of programs.
• Using VB is much more like using a window’s application than programming
for windows in the traditional power of VB comes from the fact that it is a real programming
language. All the BASIC commands and functions are available (only the obsolete and in
applicable have been removed), and it is possible to call windows functions.
• As like in windows programming environment, the VB environment also
consists of number of windows. Though often not thought of as such, the familiar dialog
boxes are also types of window. Further more, within windows all controls are regarded as
classes of window. In Visual Basic terminology windows and dialog boxes are known as forms.
• Each form will have its own controls and code associated with it. Controls
include the various types of buttons, scroll bars and edit controls used for text entry and also
menus which allow the user to make a choice
•
• from a large number of options in a structured way windows generally takes care of all the
drawing of these controls and for the logic of, for example., the editing of text in a control.
• There are variety of controls along with this, some of them are combo
boxes, picture boxes, labels, text boxes, etc., each control has some code associated with it.
These codes are executed when the controls are activated which in the windows terminology
are known as events. This gives a VB program an event-driven architecture.

25. In VISUAL BASIC all events are associated with forms or controls. For each control or
form, VB provides a list of the events which may occur. The events are chosen for
which is usually to do nothing.VB represents the latest step in the development of the
BASIC language taking it in to the field of object oriented programming.
The language constructs of almost resemble its forerunner it also provides the user
with facilities like DLL (Dynamic Linking Library that is ., functions outside the program
can be called by the program) DDE (Dynamic Data Exchange), and OLE (Object Linking
and Embedding)Through DLL windows API can be called by any programs.
DEFINITION
Visual Basic is a language, the codes are written using basic language. Visual
Basic is a descendant of BASIC.Microsoft Visual Basic Product is defined as a
programming system. Simply put this programming system is used to write Windows
based computer programs; it includes the Visual Basic language as well as number of
tools that helps you write these programs.By using Visual Basic to create customized
programs, you are not bound by the limitations of a particular “off-the shelf”
computer program; rather, you can design applications to meet your own specific
needs.

26. zegbee
• ZIGBEE:
• The mission of the ZigBee Working Group is to bring about the existence of a broad range of
interoperable consumer devices by establishing open industry specifications for unlicensed,
untethered peripheral, control and entertainment devices requiring the lowest cost and
lowest power consumption communications between compliant devices anywhere in and
around the home.
• The ZigBee specification is a combination of HomeRF Lite and the 802.15.4 specification. The
spec operates in the 2.4GHz (ISM) radio band - the same band as 802.11b standard,
Bluetooth, microwaves and some other devices. It is capable of connecting 255 devices per
network. The specification supports data transmission rates of up to 250 Kbps at a range of
up to 30 meters. ZigBee's technology is slower than 802.11b (11 Mbps) and Bluetooth (1
Mbps) but it consumes significantly less power.
• ZigBee/ General Characteristics:
• Dual PHY (2.4GHz and 868/915 MHz)
• Data rates of 250 kbps (@2.4 GHz), 40 kbps (@ 915 MHz), and 20 kbps (@868 MHz)
• Optimized for low duty-cycle applications (<0.1%)
• CSMA-CA channel access Yields high throughput and low latency for low duty cycle devices
like sensors and controls
• Low power (battery life multi-month to years)

27. Multiple topologies: star, peer-to-peer, mesh
Addressing space of up to:
- 18,450,000,000,000,000,000 devices (64 bit IEEE address)
- 65,535 networks
Optional guaranteed time slot for applications requiring low latency
Fully hand-shaked protocol for transfer reliability
Range: 50m typical (5-500m based on environment)
