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.

The above is our proposed block diagram for smart agriculture. Here we mainly using NODMCU ESP8266 controller to control all the sensors and actuators. DHT11 sensor is used to detect temperature and humidity. LDR sensor is used to detect whether the light is there in that particular place or not. LED is used to provide light. Water level sensor is used to detect the water level is high or low. In order to provide water we are using water pump.  Two channel relay module is used in order to control LED and water pump automatically. NODMCU has inbuilt wifi and which is used to send all the data to the blynk server. We can monitor all the data in the server through blynk app in any android phone.

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. We proposed automatic monitor and control using 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.
