week 14

Hai and have a nice day everyone .

 Thank you for always see my updated progress blog for my Final Year Project 1 .

So, i am  starting for week 14 today ,however , for week 13 i missed 1 week  because  i am too busy with preparation for presentation FYP 1 , Honestly ,i am feeling relieved because my presentation is going very well, Alhamdulila..

 Lets continue with my progress FYP 1.

Now , i want to update about esp 8266 wifi module. As we know, my project are related to iot ( Internet of things) . So , it must be have interconnection between the system with the cloud server .

In my project , for iot i decide to use esp 8266 as a wifi module.


ESP8266 is a 3V WiFi module very popular for its Internet of Things applications. ESP 8266 maximum working Voltage is 3.6V and its very important to note. ESP8266 has 8 pins, namely:

• RX

• VCC

• GPIO 0

• RESET

• CH_PD

• GPIO 2

• TX

• GND

 figure of ESP 8266.

Figure above showed the communicating ESP 8266 via arduino Uno

The ESP8266 is a low-cost Wi-Fi microchip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer, Espressif Systems.

This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands. The very low price and the fact that there were very few external components on the module which suggested that it could eventually be very inexpensive in volume, attracted many hackers to explore the module, chip, and the software on it.

week 12

This is week 12 .



Assalamuailaikum and hai ..

i hope everyone in this week are feeling well , This week are very busy because many test and tutorial  from another subject . But dont worry , i keep it to update my progress for my final year project 1. what i want to review in this week are about my flowchart of my project.


First of all ,lets me explain what is flowchart ?

A flowchart is a diagram that depicts a process, system or computer algorithm. They are widely used in multiple fields to document, study, plan, improve and communicate often complex processes in clear, easy-to-understand diagrams. 

The figure above showed the shape that use in flowchart that have their own meaning for every shape.As a conclusion ,every project or systems are need flowchart to show the process of each system starting with "start of process"then"followed by end of process".

This is flowchart of my project.

This flowchart are clearly described process that  involved in my project .

week 11

 Hye everyone .. OMG this is week 11 so that means i only have 2 week  more to go for presentation day .. what i can say now i am so nervous .. But as my supervisor always says " Trust yourself, you can do it " .. hmmmm.. tq sir ..For you advice , i always remember that .

For blog in this week , I am just to review my scope and limitation of my project.
Actually my project title is water quality monitoring system by using IOT .But my project are limited because the project only have scope which is at the pond or fish tanks .

There are a few of my cope and limitation of my project .

-          Designed to monitor on a small scale of fish farm such as the ponds and tanks.

The system can only monitor the water quality in a fish farm with a maximum radius of 5,000 m² and 4 meters deep.

                                                       

-          UNO R3 is used as the microcontroller

The UNO R3 is chosen as the microcontroller to be used as it is built with Wi-Fi for the information processing and make it easier to be accessed by the users. Besides , ESP 8266 IOT Wifi Uno used to connect with wifi  as a function of Internet Of Things.

-         -There is no feedback mechanism to balance the water quality

  system is designed for monitoring purpose only without any feedback or response mechanism to     balance the water quality level. However, the user will receive a

  warning via SMS when the water quality drops.

-          -The system is just a prototype.

There may be some error while running the system as it is only a prototype for now and need some upgrade to improve its function.

As we all know, every project have their own scope and limitation because of some factor .In this project i want to highlight why i use arduino as a microcontroller because the arduino are ready to use the large community . What means by larger community because in this era,engineer, industry people use the arduino in their project so it is easier me to ask them for help.Furthermore , the aduino website itself also provide the information how to use it . At the same time, it is easier me to making and develop my project .

That all for this week. tq .. see u guys next week

week 10

 This is week 10 .
For this week i have already meet my sv  , sir mohd zubir for discussion of my project then  a little bit preparation for presentation day.According  from Sir Mohd Zubir ,i need to survey the three sensor i want use for this project at Jalan Pasar or another mall that sell the all component needed. Then , i discuss with sir which is  the last sensor i want proposed is turbidity sensor .

Turbidity Sensor

Figure showed the set of turbidity sensor .

Turbidity is the measure of cloudiness of water .Cloudiness is caused by suspended solids and plankton that are suspended in water column

Table turbidity sensor specifications

Operating voltage	5V DC
Operating current	40mA(MAX)
Response time	<500mS
Insulation Resistance	100M(min)
Operating Temperature	5-90°C
Storage Temperature	-10-90°C
weight	30g

 So, for overall i have done proposed three sensors that i want to use for this project which is temperature sensor,  Ph sensor and  turbidity sensor then i already study the specification of each sensor that i mention before . ok tq 

week 9

Assalam And hai .. have a nice day ..
This is week 9 so i already meet my Sv ,Sir Mohd Zubir to discuss about next sensor i must use in this project. The sensor i will proposed is temperature sensor.So, here is the explanation and some data about my selected temperature sensor.

Figure showed  1.5M NTC Thermistor Accuracy Temperature Sensor 10K 1% 3435 Waterproof Probe

            The temperature sensor made of semiconductor material to display large changes in resistance in proportion to small changes in temperature. The resistance is determined by measuring the voltage drop produced as the small DC, went through the thermistor while the environmental temperatures are measured using Arduino ADC. It is durable enough to be used in harsh condition since the probe is waterproof and made of stainless steel sheath

Table  Temperature Sensor Specification

Measurement range	-40 to 120 °C
Length of wire	1.5 m
Size of probe	4x30 mm
Typical Dissipation Constant	5 mW/ °C
Probe insulation	> 100 MΩ

week 8

For this week , i will explain or review  about one of the my sensor that use in my project.
The sensor use is Ph Sensor.

Figure Showed Liquid PH Value Detection Sensor Module Monitoring Control Kit

The PH electrode consist of a cylinder which enables direct connection to the BNC input terminal that is suitable for most pH meter and controller. It can give almost instantaneous reading which is accurate and reliable to be used.
