PROJECT DESCRIPTION

The main objective of this project is to control the illumination of the lamp as per the requirement by using a firing angle to control the thyristors for switching the loads by alternating the voltages applied to the load.

The controlling of light illumination is necessary for certain specific applications as per the requirement. So, this system overcomes the faults in the present system and provides a solution for light illumination control mechanism of the lamp.

The proposed system uses a microcontroller of the 8051 and a rectifier-power supply. In this system, the lamp is controlled by the TRIAC, which is connected to the microcontroller with the help of the opto-isolator. The isolator is used for isolating galvanically the loads from the microcontroller. In this system, op-amp is used as a comparator to find the zero crossing of voltages. The snubber circuit is connected to the circuit for protecting the TRAIC for inductive load.

The light illumination is controlled by varying the duty cycles (PWM Pulses) from the microcontroller as per the program. The microcontroller receives the percentage of duty cycles from the matrix keypad and delivers the desired output to switch the TRIAC for controlling the illumination of light.

The future scope of this project can be enhanced by interfacing a GSM modem to control the light illumination by using SMS wirelessly.
