In this paper, we offer the entire description of the existing system followed by solutions in greenhouse monitoring. Then we have conducted a survey on the related literature and concisely explaining them to the reviewer about the proposed work. The main aim of this survey is to make a way for the readers to recognize the developments and issues in this area. This paper concentrates to provide information to the farmers to develop agriculture so that they could grow crops according to their farm conditions allowing in enhancing productivity and sales. The approach in carrying out the survey is to know about various technologies that have been implemented in monitoring the greenhouse and also to know the enhancements that could be made further. The survey has been made to analyze to what extent the farmers have been benefited or not by reviewing the various papers and to make an attempt to understand the levels of difficulties in monitoring greenhouse with exact temperature, humidity, soil moisture, water level and, aid farmers to perceive profit and also to resolve the same.
