Green House Monitoring Based on Arduino , using DHT11 for temperature and humidity sensor,Ldr for Light Intensity sensor,Mq135 for Gas sensor (CO2).

3. DEFINITION
GREEN HOUSE is a building, room, or
area, usually chiefly of glass, in which
the temperature is maintained within
a desired range, used for cultivating
tender plants or growing plants out of
season.

4. DEFINITION

5. DEFINITION
GREEN HOUSE MONITORING SYSTEM is a system
which is oversee the aspect of a green house, such
as a temperature, humidity, gasses and the light
intensity to keep the green house in the ideal
condition

6. FEATURES
• Detect temperatures
• Detect humidity levels
• Detect sunlight and artificial light
• Detect carbon dioxide

7. BENEFIT
• Define specific greenhouse conditions
• Control environmental conditions within
greenhouse
• Eliminates risk of greenhouse not being
maintained at specific environmental
conditions due to human error

8. Green House Standard ASHRAE
Temperature : 25°C
Humidity : 60-70%
CO2 : 300 ppm
light intensity : 32.000 lux

9. TOOLS

10. MIND MAPPING
DHT11
Temperature&humidity sensor
MQ135
C02 SENSOR
LDR
LIGHT SENSOR
LCD
DAQ PLX

11. PROCEDURE
1. Prepare the components
2. Arrange the components into PCB by using the wire,
corresponding wiring with the pictures that guide to connect
into arduino

12. 3. Connect Arduino into PC which have arduino
application
4. Compile sketch, make sure that sketch don’t have
any error

13. 5. upload sketch to the arduino
6. See the value of measurand on the serial
monitor, or on the LCD

14. DESIGN

15. RESULT

16. HOW IT WORK
This project are monitoring 4 indicator, such as
LIGHT INTENSITY, HUMIDITY, GASS C02,
TEMPERATURE.
This project have a set point is based on ASHRAE Standard, when the value of
measurand is on the standard value it called ideal and the GREEN LED will
turned on,
if the value of measurand approch the exceed the standard the Red LED will
turned on,
