WEEK 6

Title of activity

• To test the Water Level Sensor

Objective / content

• The idea to detect water level is simply by the basic circuit loop where the water conductivity itself can be the connector of the circuit. Simply connect the 5V and GND to the water and another two rod (jumper) that will determine the level whether it is low or high. If the water is below than Low Level Rod, then the rod will be open circuit to that 5V and GND. If the High Level Rod is touch the water, then it will detect 5V. The rod will be connected to analog input of arduino that can read the voltage from the rod.Then the output of arduino will be connected to either solenoid to drain the water or water pump to refill the water into the tank of aquarium.
• To control the output must include another circuit because output cannot be driven by arduino. Arduino usually will inject 5V to the output pin then, a relay circuit will fetch the signal and act as a switch to turn on/off the output either solenoid or water pump.

 Component List:

1. Arduino UNO
2. 12V Relay
3. 2N2222 Transistor
4. 1N4004 Diode
5. 12Vdc adaptor

Shop that sell elctronics component

  After gather all the component, the circuit is constructed on the breadboard and run the program by arduino software. 

Construct the circuit by the component in the breadboard

.

 After we construct the circuit then we demonstrate the system to Sir Halim and be verified. Sir Halim then instruct us to continue for the testing of sensor system so that the water will change automatically without pushing a button..

WEEK 5

Title of activity

• In this week,all of Muslim peoples celebrate Aidil adha Eid. My friend and i went back to our hometown and village to enjoy the weekend with lovely family.
• At the same time, we also not forget to do it some research about our final year project (F.Y.P)

WEEK 4

Title of activity

• Research on project

Objective

• The main objectives or our aim of this project is to develop the Aquarium Automatic Cleaning System which can help the consumers that has an aquarium and we create the automatic cleaning for aquarium which facilitate the user in maintaining or cleaning their aquariums.

SCOPE AND LIMITATIONS

 The scope of this project is use to detect the cloudiness of the water in the tank and automatically change it to new water. For the limitation, this system is developed in specific cloudy of water it not perfectly as turbidity sensor.

       PROJECT BLOCK DIAGRAM AND DESCRIPTION

Block Diagram Description

Water Cloudy Sensor:        Detect cloudy of the water and trigger the (M.C.U)to start                                                                   the process.

M.C.U:                                  Arduino as micro-controller will receive signal from water                                                                   cloudy sensor and send signal to solenoid to start drain                                                                     the water.

Water Level Sensor:           Water level sensor will detect the water level and send                                               signal to (M.C.U) if the water is in low level (M.C.U) will stop                                               the solenoid if the water level is in high level water pump                                                                   will stop.

Water Pump:                       When solenoid have been stop (M.C.U) will send another                                                                   signal to water pump to start pump the water.

WEEK 3

Title of activity

• Produce Gantt chart.
• Research on proposed project.

Objective

• To produce details of fyp project progress on each week.
• To find information that connected to proposed project.

Content

• Produce Gantt chart in Microsoft excel.
• Search in the internet information that related to this project.
• Make sure all the info about the dateline,sent report and the details of exhibition.

Turbidity Sensor

     Turbidity sensor works as a device that measure the cloudiness  of the water whether the water contained suspended particles that make the water turn cloudy or clear. There are many method to read the cloudiness water. One of the method is by running the water between LDR and LED. If the water is cloudy enough it will block LED and the reading from LDR would changed.

Water Level Sensor

       

       To drain and fill the water simply just connects the tank with Solenoid and Water Pump. The issue is how to control the water level. Supposedly when start draining water the solenoid will turn on and the water will flow out but, to start refill the water by water pump the solenoid must be closed off otherwise the water will drain straight to solenoid and act just like filtering the water obviously, that not the way for this project.

       To stop the water from keep drain there must be something trigger to send signal to the control unit telling that the water is drain enough the control unit will send signal to solenoid to turn off. After that the motor pump can start its part to refill the water until full. Similarly, there must be something trigger to send signal to control unit telling that the water is full enough so that water pump not continuously on.

      Usually there have been Hi-Lo water level sensors that can do the triggering job in the market. But those sensors quite not necessary because this project is run base on control unit that have build in many advantage. Therefore, from the control unit can be design a trigger circuit as replacement for Hi – Lo water level sensor.
