Week 14: FYP1:-Submit Proposal

• I need to submit the complete proposal to the supervisor. By guideline given from RPS website, I have complete the proposal on time. Before submitting the proposal, many things that need to be in the focus, for example:-

                  1. Project benefits

                  2. Project objectives  

                  3. Projects budget

                  4. Work plan to complete the project  

                  5. Component in the project

• After submit the proposal, I have to update my blog until week 14.   

  

Week 13:FYP1:- Conclusion & References

CONCLUSION

In conclusion, greenhouse is a building in which plants are grown. The basic function greenhouse is to provide a protective environment for crops/plants production.  The greenhouse environment has to be closely monitored so that plants grow in the best possible conditions. A plant that grows in an environment where temperature, moisture, light, nutrition, and pest levels are ideal and continuous will be as strong and healthy as it can possibly be. The main important things for this project are microcontroller. The microcontroller functions to control the all activities or environment in a greenhouse. The present proposal is a model to modernize the agriculture industries at a mass scale with optimum expenditure. By using this system, the gardener can save manpower, water to improve production and ultimately profit.

Week 11: FYP1:-Research about Sensor

1) TEMPERATURE SENSOR

 

The temperature sensor measures the temperature in the greenhouse. It is connected to a 5V power supply with a current limiting resistor. This limits the current to the allowable operating current of the sensor, which is between 6µA and 12µA. We chose the average resistance to guarantee the efficiency of the circuit. The sensor’s output is connected directly to the PIC. The current output of the sensor is 100µA with an output voltage ranging from 0V to 1V. Since this current output is less than the maximum current input of the PIC (25mA), a direct connection is possible. To convert the output voltage to the equivalent temperature measurement, the datasheet provides the necessary equations. The equation is as follows:

 T_A = V out - V°C

          T_C­

    Where: V_OUT = Sensor Output Voltage

                                                T_C­ = Temperature Coefficient (10.0mV/°C)

                                                T_A = Ambient Temperature

                                                V_0°C = Voltage at 0°C (500mV)

 2) LIGHT DEPENDENT RESISTOR (LDR) SENSOR

The LDR light sensor detects the light intensity shinning into the greenhouse. The output of the sensor will be in analogue ranging from 0 to 1V. Since the PIC’s maximum input current is 25mA, we set the sensor’s output current to be 20mA for extra precautionary measures. Ohm’s law was used to determine the resistance needed to limit the current at this voltage output range.

                                

 Ohm’s Law: Voltage [V] = Current [A] x Resistance [Ω] 

 3) HUMIDITY SENSOR

 

The humidity sensor is used to determine the relative humidity level inside the greenhouse. It requires a 5V power supply and can be directly connected to VCC. The output of the sensor ranges from 0V to 1V. To determine the equivalent relative humidity, the voltage output will be analyzed. As stated in the datasheet, the voltage output varies linearly with the humidity level - every 0.01V is equivalent to 1%RH. This is a very useful feature of the sensor as it helps determine the humidity level faster and more efficiently.
