INDUSTRIAL MINITORING SYSTEM BASED ON BLUETOOH CONTROLLED SENSOR ..



Bluetooh technology is used for wide range of applications. Here we make use this technology for the use of boiler control in industry.this project implementation mainly needed of Temperature sensor, Blue tooth kit, PC, PIC Microcontroller kit, LCD display and multiple devices.
The temperature sensor  is used to control the temperature of the boiler system. Boiler temperature is continously monitored and signal datas are send to the PIC unit.PIC control monitor the sensor out put and control the bluetooth kit.
The bluetooth receiver receives the data from the bluetoth transmitter. The transmitter is attached to the controller and receiver is connected to the usb port of any windows installed pc.
In pc we can make a program which monitors the range of temperature and alert if the range exeeds.

My name is RESISTOR


Hi friends, my name is resistor. I don’t know how old I was.I think I am looking so beautiful.Usually I wear different colored dresses.But my dear friends I am not showing fashion to public.Each color in my dress has different meaning.This color shows my resistance value.Many people don’t know how to calculate it.Here I put a short cut word.
Remember this string    BBROYGotBeautifulVeryGoodWife”. Now expand each capital word in its.

                             B=black
                             B=brown
                             R=red
                             O=orange
                             Y=yellow
                             G=green
                             B=blue
                             V=violet
                             G=grey
                             W=white


                           

There is tolerance value,which shows how much my value can change  to front and back.I am not moving to its details now.Friend you know I have two terminals.You can connect it in either ways, no problem here.I am a passive element with two symbolic representations.My aim is to offer resistance to electronic circuits.Many people used me as a current limitng elements to fulfill their needs in their circuits.Normally my value can not change,but some time due to temperature and voltage values there may be a small amount of change.In market I am available in variable mode also,known as variable resistor.The theory of working is similar when one person moving through street with no crowd he can move simply with out any resistance.But when he moves through a crowded street he need more power to move through this street.
                   There is a law named ohms law which shows the relation between voltage and current in a circuit,and which is given by,
                             V=IR
                             I=V/R
                             R=V/I
Generally people can connect resistor in series and parallel.But my friends there is a difference in effective value when we connected in both ways.
Here comes some electronics Indian companies which make resistor,
          GALAXY ELECTRONICS COMPONENTS
          BALAGI ENGINEERS
          MEGA ELECTRONICS
          PROGRESSIVE ENTERPRISES
          NEHA TRADING CORPORATION
          SUPERFINE METALS PVT.LTD
          CREATIVE INDUSTRIAL CORP.
          ARENA AUTOMATION
