Reasons for Use of PLC in our project


From the programming point of view, PLC manufacturers has developed standards such as statement list, structured text, ladder, function block diagram, sequencial function chart. With this standards user can concentrate on how to make their factory work and let the PLC manufacturer doing the circuitry and programming of the microcontroller inside the PLC and do the
testing for the whole unit.
1. Housing, electrical properties of inputs/outputs and power supplies are designed fo ....etc

AUTOMATIC NIGHT LAMP WITH MORNING ALARM
ABSTRACT:
Automatic Night Lamp with Morning Alarm System is a simple yet powerful concept, which uses transistor as a switch. By using this system manual works are 100% removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. This is done by a sensor called Light Dependant Resistor (LDR) which senses the light actually like our eyes. It automatically switches OFF lights ....etc

Abstract:
electrodeless lamp is a light source in which the power required to generate light is transferred from the outside of the lamp envelope by means of (electro)magnetic fields.Two systems available noe—one, plasma lamps, based on the use of radio waves energizing a bulb filled with sulfur or metal halides, and the other is, fluorescent induction lamps, based upon conventional fluorescent lamp phosphors .. and the Magnetic induction lamps are basically fluorescent lamps with electromagnets wrapped around a part of the tube, or ....etc

Introduction
This circuit automatically turns on a night lamp when bedroom light is switched off. The lamp remains ‘on’ until the light sensor senses daylight in the morning. A super-bright white LED is used as the night lamp. It gives bright and cool light in the room. When the sensor detects the daylight in the morning, a melodious morning alarm sounds.
The circuit is powered from a standard 0-9V transformer. Diodes D1 through D4 rectify the AC voltage and the resulting DC voltage is smoothed ....etc
