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 whenever the sunlight comes, visible to our eyes and activates the morning alarm.

By using this system energy consumption i ....etc

Respected Sir/Madam
I want to find some disadvantages of using LDR based automatic switch street light system.
But I am not able to find it. Please send me some disadvantages of using LDR based automatic switch street light system. I liked your site and even wanted to register on it. But due to this I will never register.
Thank You

Vaccum Brake System
The vacuum brake is a braking system employed on trains and introduced
in the mid-1860s. A variant, the automatic vacuum brake system, became
almost universal in British train equipment and in those countries influenced
by British practice. Vacuum brakes also enjoyed a brief period of adoption
in the USA, primarily on narrow gauge railroads. However, its limitations
caused it to be progressively superseded by compressed air systems starting
in the United Kingdom from the 1970s onward. The vacuum brake system is ....etc

3 Point Starter Working Principle and Construction of Three Point Starter

A 3 point starter in simple words is a device that helps in the starting and running of a shunt wound DC motor or compound wound DC motor. Now the question is why these types of DC motors require the assistance of the starter in the first case. The only explanation to that is given by the presence of back emf Eb, which plays a critical role in governing the operation of the motor. The back emf, develops as the motor armature starts to rotate in presence of the magneti ....etc

Cranes are a family, Gruidae, of large, long-legged and long-necked birds in the group Gruiformes. There are fifteen species of crane in four genera. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Cranes live on all continents except Antarctica and South America.

They are opportunistic feeders that change their diet according to the season and their own nutrient requirements. They eat a range of items from suitably sized small rodents, fish, amphibians, and insects to grain, berries, and ....etc
