PROJECT DESCRIPTION

The project is designed to maintain precise illumination of a lamp. A microcontroller of 8051 family is used along with thyristor controlled lamp for maintaining the illumination.

Illumination of a lamp varies depending on the voltage applied to it. In certain specific applications it is necessary to have controlled illumination as per requirement. This system overcomes the faults in the present system and provides a solution for light illumination control mechanism of the lamp.

This system is built by using an 8051 microcontroller and based on the principle of firing angle control of thyristors, which in turn can control the illumination of lamp. An LCD display unit is used, which displays entered percentage of the illumination through a matrix keypad.

The firing angle control of thyristors is done by the microcontroller, according to the desired percentage entered by the user. Based on this input the microcontroller will automatically adjust the power delivered to the lamp through a solid state switching mechanism.

Further the project can be enhanced by interfacing the current system with a GSM modem. The user can send an SMS with the desired percentage of illumination entered in it through his cell phone. The GSM modem accepts this message and thus controls the illumination of the lamp through microcontroller.
