ABOUT THE ISRO:The Indian space research Organization is the

space agency of the Indian government.Its primary Objective is to advance space

technology and use its application for national benifit.

The Headquarter of ISRO is at bengaluru.

ISRO is established in 1969 and managed by Department of space(DOS).

India’s first satellite ‘Aryabhata’ was built by ISRO and launched on 19 April 1975 and now ISRO has launched 77 satellite till March 2015.

In these satellite different type of satellite are launched like SLV,ASLV,PSLV,GSLV,GSLV Mk-III.

REMOTE SENSING SYSTEM

Remote Sensing is a method of obtaining information about the properties of an object without coming into physical contact with it.

Application of remote sensing

1.Meteorological

application.

2.Medical application.

3.Astronomy and Cosmology application.

4.Exploration of terrestrial bodies.5.Science of Geology.6.National security (i)Targeting (ii)Disaster mapping and monitoring. (iii)weapons monitoring.

GEOGRAPHIC INFORMATION SYSTEM Geographic information system (GIS) is a computer

system for capturing, storing, checking, and displaying data related to positions on Earth’s surface.

With GIS technology, people can compare the locations

of different things in order to discover how they relate to each other. For example, using GIS, the same map could include sites that produce pollution, such as gas stations, and sites that are sensitive to pollution, such as wetlands. Such a map would help people determine which wetlands are most at risk.

IMAGE PROCESSINGAnalyzing and manipulating images with a computer. Image

processing generally involves three steps:

1. Import an image with an optical scanner or directly through digital photography.

2. Manipulate or analyze the image in some way. This stage can include image enhancement and data compression.

3. Output the result-the output of image processing may be either an image or a set of characteristics or parameters related to the image.

Image processing is of two types:-1. Analog image processing2. Digital image processing

DIGITAL IMAGE PROCESSINGDigital image processing deals with

manipulation of digital images through a digital computer. It is a subfield of signals and systems but focus particularly on images.

How a digital image is formed

Capturing an image from a camera is a physical process. The sunlight is used as a source of energy. A sensor array is used for the acquisition of the image. So when the sunlight falls upon the object, then the amount of light reflected by that object is sensed by the sensors, and a continuous voltage signal is generated by the amount of sensed data.

In order to create a digital image , we need to convert this data into a digital form. This involves sampling and quantization. The result of sampling and quantization results in an two dimensional array or matrix of numbers which are a digital image.

OPEN SYSTEM INTERCONNECTIONOSI (Open Systems Interconnection) is reference model

for how applications can communicate over a network. A reference model is a conceptual framework for understanding relationships. 

TRAINING PROJECT “TEMPERATURE AND HUMIDITY SENSOR USING

ARDUINO”

In this project hardware is designed to measure the temperature and humidity that based on ARDUINO UNO microcontroller which controls all its functions. A humidity and temperature sensor DHT11 is used for sensing the humidity and temperature of the environment and the system displays the humidity and temperature on an LCD in the range of 20%RH to 80%RH and 0°C to +50°C respectively

Component used for the project

1. DHT11 temperature and humidity sensor

2. Wires.

3. Arduino UNO R3

4. 10K resistor for the DHT11 pull-up

5. 16x2 LCD display

TEMPERATURE AND HUMIDITY SENSOR (DHT11):

The DHT11 is a basic, ultra low cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermostat to measure the surrounding air, and spits out a digital signal on the data pin.

ARDUINO UNOArduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board microcontroller)

 and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board.

16x2 LCD DISPLAY

LCD (Liquid Crystal Display) screen is an electronic display module. They come in many sizes 8x1 , 8x2 , 10x2 , 16x1 , 16x2 , 16x4 , 20x2 , 20x4 ,24x2 , 30x2 , 32x2 , 40x2 etc .

A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits.

A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. they all have same 14 pins (0-13) or 16 pins (0 to 15). 

All LCD have •Eight(8) data pins

•Vcc (apply 5v here)

•Gnd (ground this pin)

•Rs (register select)

•Rw (read - write)

•En (enable)

•V0 (set lcd contrast)
