In this paper we have proposed conference hall automation system. We have used optimum energy management concept. When any person enters the conference hall, system senses and accordingly operate the lights and fans and saves energy. Also we have used GSM module which is interfaced with the controller. Security against fire is added, fire alarm system is activated when it detects fire and dials a call from the connected phone. The principle used is very easy and simple to implement. Hardware required for the design is not very costly and easily available in the market.
