The document describes a greenhouse monitoring system that detects temperature, humidity, light intensity, and carbon dioxide levels to maintain a greenhouse's optimal conditions. The system helps control the environment by defining specific conditions, eliminating human error risks, and ensuring conditions stay within the ASHRAE greenhouse standard of 25°C, 60-70% humidity, 300 ppm CO2, and 32,000 lux light intensity. It uses sensors like DHT11, MQ135, and LDR connected to an Arduino via a PCB board to measure values and display results.

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

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
