Power Supply – Circuit Description

The operation of power supply circuits built using filters,

rectifiers, and then voltage regulators. Starting with an AC

voltage, a steady DC voltage is obtained by rectifying the AC

voltage, Then filtering to a DC level, and finally, regulating to

obtain a desired fixed DC voltage. The regulation is usually

obtained from an IC voltage regulator Unit, which takes a DC

voltage and provides a somewhat lower DC voltage, Which

remains the same even if the input DC voltage varies, or the

output Load connected to the DC voltage changes.

PIR sensor

PIR sensors

Passive Infrareds sensors (PIRs) are electronic devices which are

used in some security alarm systems to detect motion of an infrared

emitting source, usually a human body.

The pyroelectric sensor is made of a crystalline material that

generates a surface electric charge when exposed to heat in the

form of infrared radiation.

When the amount of radiation striking the crystal changes, the

amount of charge also changes and can then be measured with a

sensitive FET device built into the sensor.

This radiation (energy) is invisible to the human eye but can be

detected by electronic devices designed for such a purpose

PIR sensor materials

The actual sensor on the chip is made from natural or artificial

pyroelectric materials

usually in the form of a thin film, out of gallium nitride

– gallium nitride (GaN)

– caesium nitrate (CsNO3)

– polyvinyl fluorides

– derivatives of phenylpyrazine

– cobalt phthalocyanine

– Lithium tantalate (LiTaO3) is a crystal exhibiting both

piezoelectric and pyroelectric properties

PIR configuration

Block process

The PIR325 sensor has two sensing elements connected in a

voltage bucking configuration.

This arrangement cancels signals caused by vibration, temperature

changes and sunlight.

A body passing in front of the sensor will activate first one and then

the other element whereas other sources will affect both elements

simultaneously and be cancelled.

The radiation source must pass across the sensor in a horizontal

direction when sensor pins 1 and 2 are on a horizontal plane so that

the elements are sequentially exposed to the IR source.

A focusing device is usually used in front of the sensor


ATMEL microcontroller and write the code to initialize the UART and

use it to send and receive data

Data you need to transmit and it will do the rest.

It transmits data at standard speeds of 9600,19200 bps etc

The advantage of hardware UART is that you just need to write the

data to one of the registers of UART and your done, you are free to

do other things while UART is transmitting the byte.

UART automatically senses the start of transmission of RX line and

then inputs the whole byte and when it has the byte it informs

you(CPU) to read that data from one of its registers

RS232 pins

UART pins

The UART always transmits data on pin P3.1,P1.3/TX

The UART always receives data on pin P3.0,P1.2/RX

The RS-232 standard defines lots of other signals other than

TX and RX used for handshaking.

Voltages

The USART input/output uses 0V for logic 0 and 5V for logic

1.

The RS-232 standard (and the COM port) use +12V for logic

0 and –12V for logic 1.

To convert between these voltages levels we need an

additional integrated circuit (such as Maxim’s MAX232).

Infrared digital communication

must have line- of-sight

direction dependent

short distances

reflection

can suffer from sunlight and tube light (TL) noise

Emitter/Detector Alignment Good alignment of the emitter and detector is

important for good operation, especially if

the gap is large. This can be done with a

piece of string stretched between and in

line with LED and phototransistor. A length

of dowel or stiff wire could be used to set

the alignment. Another method that can be

used for longer distances is a laser pointer

shone through one of the mounting holes.

The next diagram shows two methods of

aligning the emitter and detector mountings.

For best results the height of the "beam"

should be at coupler height and at an angle

across the tracks.

Relay

A relay is an electrical switch that opens and

closes under the control of another electrical

circuit. In the original form, the switch is operated

by an electromagnet to open or close one or

many sets of contacts.

GSM modem

A GSM modem is a wireless modem that works with a GSM

wireless network.

A wireless modem behaves like a dial-up modem. The main

difference between them is that a dial-up modem sends and

receives data through a fixed telephone line while a wireless

modem sends and receives data through radio waves.

A GSM modem can be an external device or a PC Card /

PCMCIA Card. Typically, an external GSM modem is connected

to a computer through a serial cable or a USB cable.

Like a GSM mobile phone, a GSM modem requires a SIM card

from a wireless carrier in order to operate.

AT COMMANDS

computers use AT commands to control modems. Both

GSM modems and dial-up modems support a common

set of standard AT commands.

GSM modems support an extended set of AT

commands.

Operations

Reading, writing and deleting SMS messages.

Sending SMS messages.

Monitoring the signal strength.

Monitoring the charging status and charge level of the battery.

Reading, writing and searching phone book entries.

GSM phone or modem supports SMS text mode

Check if your GSM phone or modem supports SMS text mode

To check if your modem supports this text mode, you can try the

following command:

AT+CMGF=1 <ENTER>

If the modem responds with "OK" this mode is supported.

DESCRIPTION 2^12 decoders are a series of CMOS LSIs for

remote control system applications.. The decoders receive serial addresses and

data from a programmed 2^12 series of encoders that are transmitted by a carrier using an RF transmission medium.

They compare the serial input data three times continuously with their local addresses.

If no error or unmatched codes are found, the input data codes are decoded and then transferred to the output pins.

The VT pin also goes high to indicate a valid transmission.

The 2^12 series of decoders are capable of decoding information's that consist of N bits of address and 12-N bits of data.
