FYP 2 PROGRESS - WEEK 8

Title

- Calculation of energy meter's power

Purpose

- To get intended calculation consumed power from energy meter based on pulse from meter energy 3200 pulse for 1 kWh which using tnb calculation (for single phase's tariff)

Description

Calculation of Pulses and Units:

Before proceeding for the calculations, firstly  keep in mind the pulse rate of energy meter. There are two pulse rates of energy meter first is 1600 imp/kwh and second is 3200 imp/kwh. So here I am using 3200 imp/kwh pulse rate energy meter.

So first I need to calculate the Pulses for 100watt, means how many times Pulse LED will blink in a minute, for the load of 100 watts.

Pulse= (Pluse_rate*watt*time)/ (1000*3600)

So pulses for 100 watt bulb in 60 seconds, with energy meter of 3200 imp/kwh pulse rate can be calculated as below:

Pulses=3200*100*60/1000*3600

Pulses = ~5.33 pulse per minute

Now I need to calculate Power factor of a single pulse, means how much electricity will be consumed in one pulse:

PF= watt/(hour*Pulse)

PF=100/60*5.33

PF=0.3125 watt in a single pulse

Units= PF*Total pulse/1000

Total pulses in an hour is around 5.33*60=320

Units = 0.3125*320/100

Units = 1 per hour

If a 100 watt bulb is lighting for a day then it will consume

Units =1*0.3125

Units = 0.3125 Units

And suppose unit rate is at the region is rm0.0218 per unit then

So have to pay for 0.3125 Units for:

Price= 0.3125*0.0218 = RM0.0068125

This is simplified equation :-

watt = (i*0.3125);

unit = watt/100;

price = unit*0.0218

FYP 2 PROGRESS - WEEK 6

Title

- Finding the suitable energy meter

Purpose

- To learn how to get input from energy meter

Description

there are two type of energy meter which is analog meter and digital meter. But the most important is how to get the pulse or signal that indicate how much energy/electricity has been used.

digital

analog

there one that i use in the project.

after research, i found one way to calculate the signal from energy meter, which is from its diode pulse which blinking each time it reach certain consume of power. 3200 pulse for 1 kWh.

FYP 2 PROGRESS - WEEK 4

Title

- Learn and research more about gsm and arduino

Purpose

- To find suitable method to calculate and get input from meter energy

Description

Booting the GSM Module

1. The SIM card is inserted to GSM module and lock it.

2. The adapter is connected to GSM module and turn it ON.

3. Waited for some time (say 1 minute) and  start to see the blinking rate of ‘status LED' or ‘network LED'(GSM module will take the time to establish connection with mobile network.

4. After the connection is set up and initiated is made successfully, the status/network LED is blink continuously every 3 seconds. The user try making a call to the mobile {number of|quantity of|amount of} the sim card inside GSM module. After hear a ring back, the gsm module has successfully established network connection.

Connecting GSM Module to Arduino

There are two methods for connecting GSM module to arduino. Regardless, the communication between GSM and Arduino module is serial. So it supposed to use serial pins of Arduino (Tx and Rx). So if choosing this technique, Tx pin of GSM module is connected to Rx pin of Arduino and Rx pin of GSM module to Tx pin of Arduino. GSM Tx –> Arduino Rx and GSM Rx –> Arduino Tx. The ground pin of arduino is connected to ground pin of gsm module. Lastly, load different programs to communicate with gsm module and  ensure it is work.

To prevent the difficulty, in this project, it can using  alternate method in which two digital pins of arduino are used for communication. It must select two PWM enabled pins of arduino  for this method. So in this project, I choose pins 12 and 13 (which are PWM enabled pins).

So given below is the circuit diagram to connect gsm module to arduino – and hence use the circuit to send sms and receive sms using arduino and gsm modem.

The connections as shown are made in the project. The program (coding) has two objectives as described below:-

1) Send SMS using Arduino and GSM Module – to a specified mobile number inside the program.

2) Receive SMS using Arduino and GSM Module – to the SIM card loaded in the GSM Module.

Description

FYP 2 PROGRESS - WEEK 2

Title of activity

-  FYP 2 Briefing and Hardware Survey

Objective

- To understand the FYP 2 subject's flow
- Dateline of progress and submission
- Survey and compare some component market price

Content

This week we have FYP 2 briefing which include all student that are taking the FYP 2's subject. It all about the dateline of the each chapter in FYP 2 that were need to submit. And general information about the FYP 2. Also, we are inform that, there will be a workshop as a guideline for chapter 1,2 and 3. 

Other activity, i survey the component price that will be used in my FYP 2.
