PROJECT DESCRIPTION

This project is designed to maintain a precise illumination level of a lamp using a microcontroller of the 8051 family along with a thyristor-controlled switch for maintaining accurate illumination.

An opto-isolator is used for interfacing the microcontroller with a TRIAC and load. A Zero crossing detector is used to perform switching at exactly zero crossing of the waveforms. An LCD display unit is used, which displays entered percentage of illumination through a matrix keypad.

Firing-angle control of the thyristor is done by the microcontroller, according to the desired percentage entered by the user. Based on this input, the microcontroller automatically adjusts the power delivered to the lamp through a solid-state switching mechanism. A snubber circuit is used for the protection of the TRIAC.

Furthermore, this project can be enhanced by interfacing the current system with a GSM modem. Thus 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 the microcontroller.

Q & A
Q:  Which microcontroller is used in this project?
A:  The microcontroller used in this project is a 40 pin IC from 8051 family.
Q:  Why TRIAC is preferred instead of relays?
A:  TRIAC is a solid state device compared to a relay which is a electromagnetic device with contact pitting problem
Q:  How can the bulb intensity be varied?
A:  The bulb intensity can be varied by delaying the firing angle of the thyristor.
Q:  Which thyristor is used?
A:  TRIAC BT136 is used as the thyristor.
