Design of wireless sensor network based fuzzy logic controller for a cold storage system

In spite of India holding the second position in production of fruits and vegetables in the world, about one third of these are wasted in post-harvest. Major chunk of post-harvest losses are attributed to lack of proper cold storage and cold chain facilities. The quality and life of the commodities are determined by their storage conditions. Hence, designing an intelligent cold storage system turns out to be very much essential in order to mitigate the post-harvest wastage of the perishable commodities. This enables remunerative prices to the cultivators in addition to making the commodities available at competitive and affordable prices to the consumers. Based on the technical standards for control atmosphere cold stores temperature, humidity, CO

level and light intensity level are the essential parameters to be monitored and controlled for maintaining their quality and life. However, currently available cold storage systems in India do not consider controlling of all these essential parameters. With an intention to address this, a wireless sensor network based fuzzy logic controller for monitoring and controlling these essential parameters is proposed here.
