New to Arduiono -- Project feasibility check

I am a newb to Arduion, and have an ambitious project to begin, after my learning phase. I want to build a sensor and transmitter using Arduino Uno board.
I want to take measurements using a sensor, and transmit the data gather every minute (60000 ms). The data being gathered and transferred is in the KB, I would even say under 50 kb. The SHT15 sensor I can get unmounted or mounted, not sure which is better.

Here is what I am using:
Arduion Uno
GPRS Board (http://garden.seeedstudio.com/index.php?title=GPRS_Shield_v0.9b)
SHT15 Sensor (http://www.sensirion.com/en/01_humidity_sensors/03_humidity_sensor_sht15.htm)

Here are my questions:
Do I need something like the Seeduino Stalker (http://garden.seeedstudio.com/index.php?title=Seeeduino_Stalker_v2.0) to gather the data?
Where would I mount the bare SHT15 chip, or the SHT15 board?
I want to use battery power, still earning about batteries, so not sure what i will need there double As or 9v. The board specs say optimal is 7-12V so I believe I would need a 9v, right or wrong?

Thank you for the help,
Charles

Hi,

SHT15 is temperature and humidity IIRC, you can find several articles on them - google +arduino +SHT15

you want to transmit once per minute, how many samples do you take per minute? (can be 1 but can be more and do some averaging or collecting)

Q: where do you want to transmit the data to? What is at the receiving end ?

No the SHT15 can be connected directly to Arduino.

Where would I mount the bare SHT15 chip, or the SHT15 board?

don’t know

Everything between 7 and 12 Volt is OK,
Q: how long must the device run - unattended?
Q: how much milliAmperes will your device take? to be deterrmined I guess
There are arduino applications that seriously considered a car battery so it can run for a year or more.

Hopes this helpes to refine your project,

Kilo bits or kilo bytes? You aren't clear here.

1) kilo bytes --- sorry for the confusion.

I want to take 1 sample a minute, I was not thinking an average over th minute, because a sampling rate at once per minute, gives me pretty accurate results.

I want to transmit the Temperature, Relative Humidity and MAC Address of the hardware. In the long run, I want it stored on a mySQL database. In the short run, ie testing, it can be texted to my phone or emailed to me.

You answered my question about mounting the bare SHT15 or boarded one, by saying I can mount it to the Arduino Uno board...so THANK YOU!!!

In terms of battery life, the thought process is run for a couple of weeks without replacing the battery. I have read some articles on how to save battery life, but I am still reading the boot up specs on some items to know if it is practical to put the device in sleep mode for my sampling rate.
