Formed control model is uses fuzzy logic to take decisions how we can protect. Formed model makes an intelligent system for control the water paths inside and outside Temples and the historical Monuments. Formed system to be installed and monitored for better results. We are trying to install and form results how it can protect from the environmental can be protected in the Less Cost.
