Electrical engineering is a field which deals with study and application of electricity, electronics and electromagnetism. Electrical engineering has subdivided into a wide range of subfields including electronics, digital computers, power engineering, telecommunications, control systems, radio-frequency engineering, signal processing, instrumentation, and microelectronics. The subject of electronic engineering is often treated as its own subfield but it intersects with all the other subfields, including the power electronics of power engineering. Electrical engineers use their skills and knowledge to solve various electricity related technical problems.
Abstract:- Todays, life is modern life in which everyone want safe and happy and workless life. So that lot of people appoint security guards. But in some case it cant affordable or it cant trust worthy so on behalf of this we developed this project
Which will helpful for security and for other purpose.
In this we used LDR & IR SENSOR. In modern house LDR sensor is used for light sensing & IR is used for gate control. & it also used for letter detection in post box. All sensors output we can see on LCD in home. If in some condition theft would come near to house then also we get some indication on alarm.
Every year ,we find more and more road accidents due to increased traffic on the roads, and if you see the statistics ,you will find that the causalities are more every year than that of 1970 Indo -Pak war. Experts says, increased motorist population, long working hours, stressful life, are the major cause. The factors are beyond one’s control , but if we could alert the driver on the highway,could save the many presicious lives.
Now days, many times out of three phase one of the phase cutout and the circuit breaker trips at that time the MSEB operator has to operate it manually by turning on the contacts of circuit breaker contact and if a MSEB operator sleeps at the time of duty at that time the hooter shouts and gives us alert.
A conveyor system is a common piece of mechanical handling equipment that moves materials from one location to another. Conveyors are especially useful in applications involving the transportation of heavy or bulky materials. Conveyor systems allow quick and efficient transportation for a wide variety of materials, which make them very popular in the material handling and packaging industries. Many kinds of conveying systems are available, and are used according to the various needs of different industries. There are chain conveyors (floor and overhead) as well. Chain conveyors consist of enclosed tracks, I-Beam, towline, power & free, and hand pushed trolleys.
Ideal gas sensor is used to detect the presence of a dangerous LPG leak in your car or in a service station, storage tank environment. This unit can be easily incorporated into an alarm unit, to sound an alarm or give a visual indication of the LPG concentration. The sensor has excellent sensitivity combined with a quick response time. The sensor can also sense is-butane, propane, LNG and cigarette smoke. If the LPG sensor senses any gas leakage from storage the output of this sensor goes low. This low signal is monitored by the microcontroller and it will identify the gas leakage. Now the microcontroller is turn on Buzzer. After few milliseconds delay, it also turn on exhaust fan for throwing gas out and continue send messages as ‘GAS LEAKAGE’ to a mobile no, written in c-code.
