I want to thank all teaching and non‐teaching staff to support us. Especially I am thankful to Mr. Mahender Bishnoi for providing this golden opportunity to work on this project, inspiration during the course of this project and to complete the project within Stipulated time duration . I would like to express our sincere gratitude to our Guides Dr. for their help during the course of the project right from selection of the project, their constant encouragement, expert academic and practical guidance. I thank Mr. Mahender Bishnoi for his valuable suggestions and use of his resources. Special thanks to our families for standing by us. Above all, I express my gratitude to God.

Monitoring and control of greenhouse environment play an important role in greenhouse production and management. To monitor the greenhouse environment parameters effectively, it is necessary to design a measurement and control system. The objective of this project is to design a simple, easy to install, microcontroller-based circuit to monitor and record the values of temperature, humidity, soil moisture and sunlight of the natural environment that are continuously modified and controlled in order optimize them to achieve maximum plant growth and yield. The controller used is a low power, cost efficient chip manufactured by Microchip having 8K bytes of on-chip flash memory. It communicates with the various sensor modules in real-time in order to control the light, aeration and drainage process efficiently inside a greenhouse by actuating a cooler, fogger, dripper and lights respectively according to the necessary condition of the crops. An integrated Liquid crystal display (LCD) is also used for real time display of data acquired from the various sensors and the status of the various devices. Also, the use of easily available components reduces the manufacturing and maintenance costs. The design is quite flexible as the software can be changed any time. It can thus be tailor-made to the specific requirements of the user. This makes the proposed system to be an economical, portable and a low maintenance solution for greenhouse applications, especially in rural areas and for small scale agriculturists. Index Terms – Wireless sensor network, Digital Agriculture, Environment Monitoring; Greenhouse Monitoring, Environment Parameter.
