Figure 1: Greenhouse picture

Development of humidity control & automatic greenhouse watering system is design to control and maintain the condition in a greenhouse like temperature, humidity and lighting. This project also used the water pump to water the chili plants in a greenhouse. All the system in a greenhouse is control by the PIC16F877A microcontroller. Consumers can always setting the time when the plant need water. Besides that, they never have to drag a hose all over the plant, never have to try and figure out if they applied enough (or too much) water, and never have to worry about watering the plant while away. The system is automatic; consumer does not have to be there to physically apply the water. They have more free time to enjoy more of your favorite activities.

Conclusion:

As for the conclusion, in order to achieve the objective of this project, the knowledge of each part of the project such as sensor,  PIC circuit, programming that using C programming as the source code of programming and microcontroller PIC16F877A as the main hardware, need to research more. This system use the subject such as microcontroller & interfacing as the source of information in order to understand the concept, theory, problem and solution of this project

         6) Conclusion about this project

Introduction of project:-

This system will constantly control and maintain the environment conditions in the greenhouse to ensure that it remains the temperature, light, humidity at the normal level and the plants will always watered two timed per day. It used three sensor which is temperature, humidity and light dependent resistor (LDR) sensor. Three sensor is provide an input signal into a microcontroller which compares these values with the preset values. Depending on the comparison value, the microcontroller will control the operation of a lamp, cooling fan, motor pump to maintain the greenhouse at the normal conditions.

Project Objective:-

1. To design a prototypes of humidity control & automatic greenhouse irrigation system
2. To design and develop humidity and temperature control system
3. To control the amount of water to the plants when it is needed
4. To detect and control the temperature and relative humidity in a greenhouse via microcontroller

Methodology:-

Figure 1: Block system

Result:-

Figure 2: Result taken from project

Poster design:-

Figure 3: Poster project

Analysis:-

From the poster it will describe everything about the project. The assessor can understand about the project from the poster. Block diagram can explain more clearly based on the block show. The block diagram shows the input and the output from the PIC. The result show the way to control the temperature, humidity, lighting and irrigation system. The conclusion is concluding about the whole project.

Conclusion :-

As the conclusion the poster is the most important thing to describe about our project. When the assessor read all the data and information on the poster it will give them satisfaction and just ask when they don’t know certain about the project.

Week 11: Fyp 2: Troubleshoot all part of this project

Tittle: Troubleshoot all part which is temperature sensor, humidity sensor, LDR sensor and motor pump
Objective: To make sure all the circuit is function
Content: 1) Testing the functionality of temperature sensor
         2) Testing the functionality of humidity sensor
         3) Testing the functionality of LDR sensor
         4) Testing the functionality of motor pump

Result:-

Figure 1: Humidity sensor function

The humidity sensor function is to detect the relative humidity in a greenhouse. So, for this project I already choose the chili plants to be experimental. The normal relative humidity for this plants is about 55%-60%. When the humidity sensor detect the wet humidity the cooling fan will be "on" to absorb air. When the humidity sensor detect the normal humidity condition in a greenhouse the cooling fan will be "off".

Figure 2: Temperature sensor function

The temperature sensor function is to detect the temperature in a greenhouse. The normal temperature for plants in a greenhouse is 28 - 29  Celsius. When the temperature sensor detect the high temperature the cooling fan will be "on" to remove air in a greenhouse. When the temperature sensor detect the normal temperature condition in a greenhouse the cooling fan will be "off".

Figure 3: LDR sensor function

Light dependent resistor (LDR) sensor function is detect light. When the sensor is detect no light in a greenhouse the lamp will be "on" while sensor detect light  the lamp will be turn "off".

The motor pump function to water the plants in a greenhouse two times per day there are in the morning and evening. The motor pump will be on and off depends on the setting time on the control panel.


Analysis:-
All the sensor will be programmed to ensure the greenhouse close to the normal condition. The sensor involved in this project are humidity, temperature and light dependent resistor (LDR) sensor. The output for humidity and temperature sensor is cooling fan. It is function to remove and absorb air in a greenhouse. Lamp is the output of LDR sensor and its function to make sure intensity in a greenhouse have a normal condition.

Conclusion :-
As the conclusion, the output of this project only activate depends on the signal from the microcontroller.

Week 10: FYP 2: Conctruct greenhouse prototype

Tittle of project: Construct greenhouse prototype

Objective: To ensure that the greenhouse prototype is built according to the correct dimensions

Content: Construct the greenhouse prototype by using acrylic

Result:-

Figure 1: During construction

Figure 2: After construction

Analysis:-

From the picture above shows the greenhouse prototyping before and after. This project wall and roof is built by using acrylic. The design is basically get from the internet based on the existing product. The wire more important because it can make short circuit, it will damage for this project. The prototype also small, so it is easy to carry and testing the hardware.

Conclusion :
To make some design, we must take note all this aspect such as material that will be used, their costing, product, sizing, item endurance and also their usage. If we miss some of that part, the design will not completely useful.
