ppt for greenhouse monitering and controlling using 8051 microcontroller
In today s greenhouses, many parameter measurements are required to monitor and control for the good quality and productivity of plants. But to get the desired results there are some very important factors which come into play like Temperature, Humidity, Light and Water, which are necessary for a better plant growth. Keeping these parameters in mind I have built an Automatic Green House Controlling and Monitoring System over GSM module using Arduino. This system is very efficient for growing good quality plants. The other important part of this project is that it is fully automatic. Arduino automatically turns on and turn offs the appliances.
These days GSM Module is widely used in Green House Monitoring. Here in this project by using GSM Module we can keep information about the affects of climate on plants. The system shall also demonstrate climatic changes which affects the plant in its productivity and quality etc. The main purpose of coming up this project is to built an Automatic Green House Monitoring in which GSM module sends the information about Temperature, Humidity, Light intensity, Soil moisture and status of appliances (Fan, Sprays, Artificial Lights and Water pump) that are connected with circuit for controlling Green House effects or Green House parameters (Temperature, Humidity, Light intensity and Water supply for plants).
Temperature
The temperature sensor is used for sensing temperature. When temperature exceeds from a defined level or critical level, the system automatically turns on the fan and a message is also send to the owner or the operator with information of all parameters (Temperature, Humidity, Light intensity and Electrical appliance on off status). And when the temperature comes in normal range or comes below the defined level Fan turns off automatically.
Humidity
Humidity is measured by using the humidity sensor. If the Humidity of the environment is below the defined levels, sprays are automatically turned on and if the humidity level exceeds from the defined level sprays are automatically turned off. But here in this project instead of a spray I have used CFL light to denote the spray. A status or notification message is also send to the owner by the system using GSM Module.
Light Intensity
Light intensity is an important factor for the plant growth. If the light intensity is low then it affects the growth of the plants. To resolve the problem of low light, artificial lights are used. Here in this project 100 watt bulb is used for demonstration. When light intensity is lower than a defined level, the artificial lights turns on, and when the light intensity comes in normal range artificial lights automatically turns on and a notification message is also sent to the owner.
