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.
