Description:

Greenhouse monitoring and controlling project is used to measure the various parameters like Temperature, Humidity, Light and soil moisture. Microcontroller displays these parameters on a LCD. Temperature, Humidity and Light is sensed by respective sensors, soil moisture is sensed by 2 thin metal rods or metal wires. Sensor output of Temperature is amplified and along with other 3 sensors, it is given to Analog to Digital Convertor ADC. Microcontroller controls these parameters and keeps them below predefined levels using relay interface and motor drivers. These relays can be connected to Fan/Heater and DC motors can be connected to respective devices. For demo purpose we have connected a 12 volt DC fan and a 12 volt DC bulb and two 12 volt DC motors. Values of temperature, humidity, light and soil moisture are send to a computer through serial port. These values can be displayed on PC using hyper terminal.

Monitor and Control of Greenhouse Environment

Description in detail:

It mainly consist of following blocks:

1. Sensors: we are going to use temperature sensor, humidity sensor and light sensor to sense temperature humidity and light respectively. Metal thin rods or wires are used to sense soil moisture. These sensors sense the parameters and gives corresponding voltage output.

2. Amplifier: As the voltage output from the sensors is in miliVolts, it has to be increased to 0 to 5 volts range. We are going to use linear amplifier for this purpose.

3. ADC: The main part of our project is microcontroller which reads only digital input. (0V & 5V) But the output of Amplifier is in analog form, so it has to be converted into digital format, for this purpose we are going to use ADC to convert analog output from amplifier into the digital output to be given to microcontroller

4. Microcontroller: This is the CPU (central processing unit) of our project. We are going to use microcontroller of 8051 family. The various functions of microcontroller are like:

I. Reading the digital input from ADC which is derived from Temperature and Light sensor. II. Sending this data to LCD so that the person operating this project should read the values of temperature and light. III. Controlling the parameters like Temperature, light, turning On/Off the respective relays IV. Sending the values of temperature and light to the computer using serial port

5. Relay: We have used 2 relays in our project. First one will be turned on when the temperature goes above the desired value. And the second relay will be turned on when humidity goes above the desired value. (e.g. if the desired value of temperature is 35 degree C and for humidity it is 50%, then Relay 1 will be turned on when temperature is 36 or above and Relay 2 will be turned on when humidity is 51 or above)

6. DC Motors: We are going to use two 12 volt DC motors. First DC motor will be turned on when Light goes above threshold level. Second DC motor will be turned on when Soil moisture goes below threshold level.

7. PC Interfacing: We are going to use max 232 IC for pc interfacing, the values of temperature and light will be sent to pc when the key is pressed

Applications and Advantages:

1. Can be used in green houses to control the temperature, soil moisture, humidity and light for the proper growth of plants

2. With little modification, this project can be used in Mechanical companies to measure various parameters of operating machines like temperature and light.

3. Temperature monitoring and controlling action can be used in home or various halls like conference room, seminar hall to control the temperature of room

Future Development:

1. We can monitor more parameters like Humidity, PH of soil, pressure, water level and at the same time control them

2. We can send this data to a remote location using mobile or internet

3. We can draw graphs of variations in these parameters using computer

Question and answers about this project:

Question: Can we add soil moisture sensor in Greenhouse monitoring ?

Answer: Yes, we can monitor soil moisture, but for that we have to use 2 metal probes. These should be inserted into soil. If moisture is more then the conductivity will increase.

Question : I need some modifications in project. If possible make sensors wireless. It should be have good big life and good protection from high voltage. A isolating switch should be there in every controls. Can you implement these changes ?

Answer : It seems that you need to use it for actual use in greenhouse. Our project are educational projects and are for educational purpose.

      Hi HemalathaRavikumar, now a days some greenhouse systems are using manually controlled devices. The farmers or persons operating it are very well aware of environment situations. They know when to turn on the fan or heater and during which time period of day. But now some greenhouse system have started using automatic controlling systems.
