Week 9 - Research on the Internet Enabled Microcontroller

As salam..

Regarding on the post last week..

Since the plethysmograph still in the same result.

I had met my supervisor, Sir Zul and informed him

the problem that I faced. 

He suggested for me to buy the exactly type 

of sensor that shown in the schematic circuit.

There are SFH 487 for IR and 

SFH 309 FR for photodetector. Currently I'm

already had the SFH 487. Just need to make an 

order for SFH 309 FR. For me to wait the delivery 

might takes few days.

I'm proceed to find out the "Remote System" part in

my project, whether by applied the internet or wireless.

Refer on my proposal for the last FYP Semester 1,

I had found the ioBridge IO-204 was quite 

compatible to act as a remote. This IO-204 is applied

by connecting to a Local Area Networking (LAN) using 

10/100/1000 Base-T-Ethernet and then establishes and 

encrypted connections to ioBridge web server.

But unfortunately, this module not sold in Malaysia.

Even, I buy this module at the out of country, if any 

problems come it might difficult for me to be refer of.

Then, this module also used the internet cable, and 

the price is quite high because plus with the shipping.

Other thing, I'm thinking when the time I want to 

present my project, where can I plug in the internet cable.

From the few matters, I have to decide to find other 

module that might be solve the matters and most important 

is compatible with my "Remote System". 

So, I've found a few modules that related with Arduino

and mostly I found is better to be used 

a wireless application. The Arduino also has the 

Wifi Shield Arduino but in Malaysia still not listed in 

market. 

Then I found DF Robot. Mostly the module from 

DF Robot is related with Arduino.

So, by doing the survey with comparing the price

and the features. I've decided 

to choose Wifi Shield V2.2 for Arduino. 

Below are some pictures of modules that I found:

Wifi Shield Arduino (prefer to use this)

Wifi Shield V2.2 (final choose)

The reason I'm chosen this Wifi Shield V2.2:

(a)   This product is listed in Malaysia market.

(b)   Easy for me to refer if has any problem with this module.

(c)   It's related with Arduino

(d)   This provide the documentation how to set up and the tutorial.

I'm already make an order and waiting for the delivery.
