I'm a Developer

Hello There Again People,,!!!

Good morning, its quite cold and quite around here at Shah Alam,... This week i make a revision about the developing android application using Java Development Kit, which will be used to develop application for monitoring data in smartphone from the output of the PPG. As i know, Android is open source and Google releases the code under the Apache License. The open source code and permissive licensing allows the software to be freely modified and distributed by device manufacturers, wireless carriers and enthusiast developers. Additionally, Android has a large community of developers writing applications that extend the functionality of devices, written primarily in a customized version of the Java programming language.

Java Development Kit (JDK) includes a complete JRE (Java Runtime Environtment) plus tools for developing, debugging and monitoring Java applications. For this project i decided to use Android Development Tools (ADT) which is a plugin for the Eclipse IDE that is designed to give you a powerful, integrated environment in which to build Android applications.

There you are, one of the simple application that success by me. The software of the developer kits can be downloaded at here http://developer.android.com/sdk/index.html... Happy Developing.....Bye nowww..

Decide Which One is the Best Communication Technology

Communication technology really confusing, because for me this technology almost the same which is to receive and transmit the data. The differences is that, how much the distance can this data will be transmitted or the limitation which is depends on the applications that applied to it. 

For this project which can be used and view to other place which far away for example, the PPG is attached to your grandparents at Sarawak and monitor it through smartphone to your place at Kuala Lumpur. This is quite long range since there are South China Sea separating you and your loves one. 

To overcome this problem, GSM is suitable choice. This is because, GSM enables individuals to be reached via the same mobile number in up to 219 countries. GSM uses General Packet Radio Service (GPRS) for data transmissions like browsing the web. 

Time to Learn About Networking Technology

Hello again,,,

I have few knowledge about communication technology which is used in our life. There are bluetooth, GSM, RF module and etc.

What i had research about Bluetooth wireless technology is types of networking and communication that is popular standard in the communication arena and it is convenient, easy to use and has the bandwidth to meet most of today's demands for mobile and personal communications. Bluetooth technology handles the wireless part of the communication channel, it transmits and receives data wirelessly between these devices. It delivers the received data and receives the data to be transmitted to and from a host system through a host controller intergace (HCI).

About the GSM, (Global System for Mobile communications) is an open, digital cellular technology used for transmitting mobile voice and data services. GSM supports voice calls and data transfer speeds of up to 9.6 kbps, together wuth the transmission of SMS (Short Message Service). The use of harmonised spectrum across most of the globe, combined with GSM's international roaming capability, allows travellers to access the same mobile services at home and abroad.

For the RF module (Radio Frequency Module) is a small electronic circuit used to transmit and receive radio signals on one of a number of carrier frequencies. RF Modules are widely used in electronic design owing to the difficulty of designing radio circuitry. Design engineers will design a circuit for an application which requires radio communication and then "drop in" a radio module rather than attempt a discrete design, saving time and money on development. RF Modules are most often used in medium and low volume products for consumer applications such as garage door openers, wireless alarm systems, industrial remote controls, smart sensor applications and wireless home automation systems.

I have to choose which one is suitable for my project which is Graphical User Interface for Monitoring Data in Smartphone. As we all know, smartphone already has its own networking system. And now, we just have to build transmitter for it to receive the data into the smartphone.

That's all for now....See you again in next week....

Now I Know, Medical Electronic Are Not That Simple....

Nice to meet you again......

Didn't realized its already week 3!! I met my supervisor Thursday before, and i show him the DIY PPG that i found on the internet. We had discuss about the DIY PPG. The cost is estimated around RM70.00. All of the components and the can be found as listed at table below.

Component for PPG	Vendor
MCP6004 IC	Online RS Component/jalan pasar
14 pin DIP socket	Jalan pasar
1k,150R,47k,5k potentionmeter,10k,680k,6.8k resistor	Jalan pasar
100nF,4.7uF	Jalan pasar
PCB	Jalan pasar
5 pin header	Jalan pasar
2n3904 transistor	Jalan pasar
Tcrt 1000 Reflective Optical Sensors	Online RS component/jalan pasar
3mm red led	Jalan pasar

But, i told my supervisor, that we can buy online for the complete PPG device which only cost 18 dollar. After few discussion, we found that there are disadvantages to buy things that we doesn't have experience about it. There are:-

• We don't know the output of the devices such as the sensitivity of it
• We don't know if modification of the circuit will effect too much of the circuit
• How long will the devices arrived at our place

Then, because of that matter, Sir Saiful Yusri suggest that to used the device that he used before for his students project. But, we have to wait around 2 weeks minimum for the device to be delivered. Though it is required 2 weeks, don't think that i'm on VACATION and not updating the blog...Will keep in touch in next blog..bye now...sleep..zzzzzZZZZzz

Wow!! Let's Get Started

Good Morning People,!!

The first study is about the Photoplethysmography (PPG). PPG is the devices that can measured beat rate of a person. Heart rate is the number of heartbeats per unit of time, typically expressed as beats per minute (bpm). So then, i have to study things that out of my major, which is about medication. What i search, due to individuals having a constant blood volume, one of the physiological ways to deliver more oxygen to an organ is to increase heart rate to permit blood to pass by the organ more often. Normal resting heart rates range from 60-100 bpm. Bradycardia is defined as a resting heart rate below 60 bpm. However, hearts rates from 50 to 60 bpm are common among healthy people and do not necessarily require special attention. Tachycardia is defined as a resting heart rate above 100 bpm, though persistent rest rates between 80-100 bpm, mainly is they are present during sleep maybe signs of hyperthyroidism or anemia.

This is just enough for my basic about health and medication, before developing heart beat rate devices that can view by smartphone via wirelessly. Then, i have to search the types of PPG that suitable to make it as Graphical User Interface for monitoring data in smartphone. Which the output from the PPG is send via wirelessly. 

Research have been made, i found that a DIY photoplethysmographic sensor for measuring heart rate is more easier and not using much budget. Therefor, future modification of the PPG is easy to be done since there are diagram which still can i study with my supervisor. For more information regarding the DIY PPG can be found here http://embedded-lab.com/blog/?p=5508... See you in the next blog... Thanks for reading my blog until the 3rd week.
