http://microcontrollerslab.com/green-house-intelligent-control-system/

Green house intelligent control system is designed to protect

the plants from more cool and hot weather and additional

control system is included to save power by making fans and

lights automatically turn on and off with the help of intelligent

control system. In this project, the intelligent control system is

developed using microcontroller and sensors. Green housesystem has a very important use now a days in the agriculture

field.Some plants need the specific amount of water for their

proper growth and more productivity, therefore farmer should

provide them the proper quantity of water. But it’s difficult for

the farmer to get a estimation for quantity of moisture in soil.

But in this project moisture sensor is used to to provide this

facility with a intelligent control system.

MAIN FUNCTIONALITY OF PROJECT

Block diagram below shows the main functionality of green

house intelligent control system. Four sensors are used to

measure different parameters of green house system which

includes temperature sensor, light sensor, humidity sensor,

moisture sensor. Four relays are used to control four respective

loads as given below:

LM35TEMPER TURE

SENSOR :

When temperature becomes greater than 25 degree,

respective relay become energize to operate the fan and when

temperature becomes lower than 20-degree relay turn off the

fan by getting control signals from microcontroller.

PIC16F877A microcontroller analog to digital converter

module is used to read temperature value and to operate relay

which in turn operate the fan. To know more about temperature

sensor and its working, go through the following article :

DIGITAL TEMPERATURE SENSOR USING PIC

MICROCONTROLLER

LIGHT

SENSOR :

Light dependent resistor is used as a light sensor. LDR is kind

of variable resistor which resistance changes with the change in

light intensity. So LDR resistance is converted into intensity of

light by using LDR resistance and intensity of light formula.

PIC16F877A microcontroller is used to measure intensity of

light. When intensity of light fall under a certain limit,

microcontroller provide signal to relay to turn on light and when

video, pictures, code and

schematics. Please

support our efforts.

intensity of light raise upto a certain limit , microcontroller

provide signal to relay to turn off fan. So light sensor is used to

add automatic light switching functionality in the green house

system, if you don’t have much money to afford a gardener,

then you can use green house intelligent control system to

make your green house self-operating.

HS1101 HUMIDITY SENSOR :

Humidity sensor is used to check level of moisture in air

Because greater or less humidity level in air can also effect

growth of plants. Humidity sensor HS1101 is used to measure

level of moisture in air. HS1101 is a capacitative type humidity

sensor, So additional circuit is used to convert change in

capacitance of humidity sensor into frequency and frequency

is measured with the help of microcontroller. Measured

frequency is converted back into humidity using a algorithm in

microcontroller programming. To know more about humiditysensor and its working, I suggest you to go through following

article :

DIGITAL HUMIDITY SENSOR USING PIC

MICROCONTROLLER

If humidity becomes greater than a specified limit,

microcontroller gives a signal to respective relay to turn on

sprinter which is used to maintain a humidity level in the air and

when humidity level comes back to a normal limit,

microcontroller gives a signal to respective relay to turn off

sprinter.

MOISTURE SENSOR :

Moisture sensor is used to measure level in soil. A wire strip is

used to measure moisture of soil. Wire strip has a specific

resistance at specific moisture, but when moisture increases,

the resistance of wire strip starts decreasing and similarly when

moisture decreases, resistance become higher. PIC16F877A

used to measure moisture level and to turn on and off water

pump with the help of relay.

SIMULATION :

For simulation purpose, I have connected four LED’s instead of

real load to check project working and code. LCD is used todisplay digital values of temperature, light , humidity and

moisture. LCD also display the status of devices either they are

on or off. As shown in the figure below.

APPLICATIONS AND FUTURE ADVANCEMENTS :

So this project can be easily used in any green house system to

make to self-operated and automatic control of devices. You

can also add extra functionality in this project by adding

wireless communication to send values of sensors and status of

devices to someone which is not at remote location.
