Description

ABSTRACT

In present scenario, there is no mechanism to find where irrigation is needed. In this Project, we made Zigbee wireless sensor network for monitoring the humidity level by Deploying moisture sensors in the land to detect the places where the water content is low and some more environmental monitoring parameters. From the above methodology we Can conserve water and minimize the problem of water logging in the land. We used humidity Sensor to sense the weather. By this ,  farmers can get idea about the climate. If There is any chance for rainfall; the farmer need not irrigate the crop field. Due to this we can Conserve water and also power since we didn’t turn on motors. Nowadays in the crops the Fertilizer level is increasing, which affects people. By using pH sensors we get the Information about the soil and analyze the acid level of the soil. By which we can apply fertilizer To the place where it needs, also we can avoid over fertilization of the crops. Temperature is a Randomly varying quantity in the environment of paddy field. Temperature reading gives Information to the farmer. By using temperature sensors we can detect the temperature, and Irrigate the water to the crop. 

This  project  reports  the  design  and  development  of  a smart  wireless  sensor  network (WSN) for  an  agricultural  environment. Monitoring  agricultural  environments  for  various factors such  as  temperature  and  humidity  along  with  other factors can be of significance. The ability to document and detail changes  in  parameters  of  interest  has  become  increasingly valuable.  Investigations were performed for a remote monitoring system using Zigbee. These nodes send data wirelessly to a central server,  which  collects  the  data,  stores  it  and  allows  it  to  be analyzed and displayed as needed.  

INTRODUCTION

As it is well known, greenhouse is a building where plants are grown. Greenhouses are often used for growing flowers, vegetables, fruits, and tobacco plant. Basic factors affecting plant growth are sunlight, water content in soil, temperature, CO2 concentration etc. These physical factors are hard to control manually inside a greenhouse and there is a need for automated design arises. Greenhouses are very useful for following reason it they provide an optimal temperature around plants, protect them from weather extremes, extends the growing season, allowing you to sow plants earlier and harvest plants later and allows economic crops such as tomatoes, cucumbers, melons and aborigines to crop more successfully
