Intensity Control of Room System

AIM:      The main aim of Intensity Control Of Room System project is to design an equipment which controls the intensity of a room.

DESCRIPTION:                       The block diagram mainly consists of microcontroller, triac, and keys. The main concept behind this intensity control is gate width. The device is controlled based on the gate width. By pressing the keys the intensity control is obtained. When a key is pressed it gives signal to the microcontroller and the micro controller gives gate pulses to the triac. These gate width is obtained in the triac by triggering it at a certain firing angle. So when the HIGH key is pressed the triac is triggered at less firing angle and the gate width of the pulses is more hence the intensity of the device is increased. In the same way when the LOW key is pressed the triac is triggered at more firing angle and gate width of the pulses is decreased and hence the intensity of the device is decreased. Hence just by pressing HIGH and LOW keys the intensity of the bulb is controlled by using triac and microcontroller.
