Objective

INTRODUCTION OF PROJECT“GSM based Control System” implements the emerging applications of the GSM technology. Using GSM networks, a control system has been proposed that will act as an embedded system which can monitor and control appliances and other devices locally using built-in input and output peripherals.

Remotely the system allows the user to effectively monitor and control the house/office appliances and equipments via the mobile phone set by sending commands in the form of SMS messages and receiving the appliances status.

The main concept behind the project is receiving the sent SMS and processing it further as required to perform several operations. The type of the operation to be performed depends on the nature of the SMS sent.

GSM (Global System for Mobile Communications): It is a cellular communication standard. SMS (Short Message Service): It is a service available on most digital mobile phones that permit the sending of short messages (also known as text messaging service).Technology has advanced so much in the last decade or two that it has made life more efficient and comfortable. The comfort of being able to take control of devices from one particular location has become imperative as it saves a lot of time and effort. Therefore there arises a need to do so in a systematic manner which we have tried to implement with our system. The system we have proposed is an extended approach to automating a control system.

The new age of technology has redefined communication. Most people nowadays have access to mobile phones and thus the world indeed has become a global village.

At any given moment, any particular individual can be contacted with the mobile phone. But the application of mobile phone can not just be restricted to sending SMS or starting conversations.

New innovations and ideas can be generated from it that can further enhance its capabilities. Technologies such as Infra-red, Bluetooth, etc which has developed in recent years goes to show the very fact that improvements are in fact possible and these improvements have eased our life and the way we live.

GSM Based Smart Irrigation ControlBackground

What is GSM TEChnologyGSM (Global System for Mobile Communications, originally Groupe Spécial Mobile), is a standard developed by the European Telecommunication Standard Institude (ETSI) to describe protocols for second generation (2G) Digital Cellular Network Used By mobile Phones . It is the de facto global standard for mobile communications with over 90% market share, and is available in over 219 countries and territories. The GSM standard was developed as a replacement for first generation(1G)analog cellular networks, and originally described a digital, circuit-switched network optimized for Full Duplex and voice Telephony This was expanded over time to include data communications, first by circuit-switched transport, then Packet data transfer by GPRS (General Packet Radio Services) and EDGE (Enhanced Data rates for GSM Evolution or EGPRS).

This GSM Modem can accept any GSM network operator SIM card and act just like a mobile phone with its own unique phone number.

Advantage of using this modem will be that you can use its RS232 port to communicate and develop embedded applications.

Applications like SMS Control, data transfer, remote control and logging can be developed easily. It can be used to send and receive SMS or make/receive voice calls. It can also be used in GPRS mode to connect to internet and do many applications for data logging and control. In GPRS mode you can also connect to any remote FTP server and upload files for data logging. Supports features like Voice, SMS, Data/Fax, GPRS and integrated TCP/IP stack.APPLICATIONS SMS based Remote Control & Alerts Security Applications Sensor Monitoring GPRS Mode Remote Data Logging

GSM MODULE 300

A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Printed circuit boards are used in all but the simplest electronic products.

PCB DESINGNING

Printed circuit board artwork generation was initially a fully manual process done on clear mylar sheets at a scale of usually 2 or 4 times the desired size.

MANUFACTURING1.PatterningIn subtractive methods the unwanted copper is removed to leave only the desired copper pattern. . Direct laser imaging techniques are sometimes used for high-resolution requirements.

1.Design

PatterningIn subtractive methods the unwanted copper is removed to leave only the desired copper pattern. In additive methods the pattern is electroplated onto a bare substrate using a complex process.

The pattern in the manufacturer's PCB CAM system is usually output on a photomask (photo-tool, film) by a photoplotter and replicated via silk screen printing or by exposing on a photo-sensitive photoresist coating. Direct laser imaging techniques are sometimes used for high-resolution requirements.

Manufacturing

Additive processes adds desired copper traces to an insulating substrate. In the full additive process the bare laminate is covered with a photosensitive film which is imaged (exposed to light though a mask and then developed which removes the unexposed film).

Additive Process

Chemical etchingChemical etching is usually done with ammonium per sulphate or ferric chloride

Holes through a PCB are typically drilled with small-diameter It is also possible with controlled-depth drilling, laser drilling, or by pre-drilling the individual sheets of the PCB

Assembly In surface-mount construction, the components are placed on pads or lands on the outer surfaces of the PCB

Copper thicknessCopper thickness of PCBs can be specified as units of length (in micrometers or mils) but is often specified as weight of copper per area (in ounce per square foot) which is easier to measure

POWER SUPPLY

Practical View

It basically operates as an ON/OFF toggle switch controlled Its output is high at power on and gives 5 volts. When it senses pulsed IR rays, its output becomes low.

TransformerA transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits

Bridge rectifierWhen four diodes are connected as shown in figure, the circuit is called as bridge rectifierOne advantage of a bridge rectifier over a conventional full-wave rectifier is that with a given transformer the bridge rectifier produces a voltage output that is nearly twice that of the conventional full-wave circuit.

A transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits. A varying current in the primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic flux through the secondary winding. This varying magnetic flux induces a varying electromotive force (emf) or voltage in the secondary winding. Transformers can be used to vary the relative voltage of circuits or isolate them, or both

Transformer

When four diodes are connected as shown in figure, the circuit is called as bridge rectifier. The input to the circuit is applied to the diagonally opposite corners of the network, and the output is taken from the remaining two corners

Bridge Rectifier

IC Voltage Regulator LM7805 is a voltage regulator integrated circuit. it is a member of 78xx series of fixed linear voltage regulator ics.

The voltage regulator ic maintains the output voltage at a constant value. the xx in 78xx indicates the fixed output voltage it is designed to provide. 7805 provides +5v regulated power supply. capacitors of suitable values can be connected at input and output pins depending upon the respective voltage levels.

ResistorA Resistor is a heat-dissipating element and in the electronic circuits it is mostly used for either controlling the current in the circuit or developing a voltage drop across it, which could be utilized for many applications. There are various types of resistors

Crystal Osscilator A piezoelectric crystal is an electronic circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.
