ABSTRACT

In agricultural country like India, greenhouses form an important aspect of agricultural and horticulture sectors. In greenhouses, plants are grown under favorable climatic conditions for its production and growth. Thus monitoring and control of greenhouse environment is necessary for production and management of greenhouses. This project is designed to monitor and control the indoor humidity and weather conditions affecting the plants using embedded system and Android mobile phone. The android phone is connected to a central server which then connects to microcontroller and humidity sensor via serial communication. Thus the sensor records and manages the required weather conditions proved to be appropriate for plant growth

INTRODUCTION

There is continuous increase in demand for food production technology. India is a country where the economy is dependent on agricultural produce. Agricultural means can satisfy the food production demand. But due to isotropic climatic conditions, lack of water reservoir, agricultural produce does not meet the demands. At the present scenario, farmers have been using different irrigation technique for increasing production. These techniques were done by human intervention. But due to this sometimes either the plants consume more water or the water reaches late up to the plants. This ultimately affects the plant growth. Also there are many such problems associated with it. To overcome from this problem, we can use an automatic micro controller based system. For automatic monitor and control we are developing an embedded system which will record the temperature, moisture and other parameters that will control the environmental conditions in the plant field. Moreover for effective control, an android application is used along with embedded system.

SYSTEM OVERVIEW

The system is a greenhouse system in which there are four sensors. These sensors act as input to the microcontroller system. The input feed provided to the microcontroller is in the form of analog data. This data is converted by the controller into digital format.  on the android phone via wifi. Thus the monitoring of temperature, moisture and other parameters is done automatically. Once the parameter values are monitored they can be control by the embedded system which is built with coding. This is automating controlling system. The android phone is operated by the user. The android application is used for controlling as per the user knowledge and required output
