hi
im new to Arduino, i got the Arduino UNO
i want to make a bracelet for kids ! that has a GPS and a body temperature sensor
that data collected i need it to be transmit to a webpage.
can you please guide me 
i don't know what the exact pieces i should buy
and it have to be small for that the UNO isn't suitable .
i looked up and found gemma ? is it alright?
What is your programming and electronics ability?
Weedpharma
i know java
and i started learning about electronics recently
Modify your Original Post and make the title useful. What about "How to make bracelet with GPS and temperature"
Where do you want to be able to view the GPS and temperature values?
Do you mean air temperature, or the bracelet wearer's body temperature?
Does the dollar sign in the title imply that you're willing to pay?
Do you want me to move this thread to "Gigs and collaborations"?
I think 
is probably the smiley for Embarrassed, blushing

What is the objective of this ? Are also wanting to transmit the collected data somewhere ?
If you also want to transmit the data, you should think of how (GSM etc) and how you are going to power all that lot.

i want to make a child safety product that let parent check online the location and body temp of their child.
i really need to know is adafruit gemma okay for such project?
First get a prototype working, without regard to size. You will be amazed at how complicated the programming can be and how much time it will take to get it working (assume months). Any Arduino will do for the prototype.
Once the prototype is working perfectly, design a bracelet that can contain all the parts.
Why temperature and location? Is temperature such a meaningful key parameter?
What's your use case scenario? What âge for the target kid?
Or is that just for you to explore ideas?
(Programming an app for a smart watch would probably be more reachable - I don't believe any individual has the capacity tonbuikd something small enough to fit on the wrist an be powered on full day, with the functions you list at a reasonable cost )
I think the greatest problem you'll have - even after the required multi-million$ investment, will be the mechanical construction to make it durable, comfortable and functional.
As mentioned above - get your prototype working in a jiffy box, then shop around for investors.
When you show them the result, they'll be falling all over you to make it smaller. (Others have tried)
Keep in mind the GPS, battery and radio-modem will need to be housed in a water and damage resistant housing. To get these in custom small form factors - you'll need to order a million of each to get the manufacturers on board. Remember to provide heat dissipation that won't interfere with your body temperature sensor.
I'd guess your jiffy box prototype will cost you $50-100K in equivalent paid parts/hours/effort over 6+ months with testing - then allow another $100K for investor shopping - after that, the sky's the limit when you start getting orders. Good luck.

You might be able to make such a thing with a gemma, but it wouldn't be my first, or even tenth choice. Gemma has less data pins available than nearly any other board. Bear in mind that in addition to the processor, you will need the temperature circuit, the GPS module and antenna, a WiFi module, and a power source with regulating circuitry.
This ain't a first project.
... body temp of their child....
Come to think of it, a WiFi module would require that the child be in a WiFi hotspot. Take a look at this Iridium phone module. AFIK, Iridium is available anywhere, anytime, and I think it includes GPS. You may also want to incorporate heart rate, GSR, and blood oxygen (through an earlobe clip - maybe make then as earrings or gages) of the kids, so you can know the level of stress they are facing. It sounds like you could make a ... large amount of money , with a project like this.
Perhaps just hiring a bodyguard would be more practical though, but not nearly as Orwellian thorough.

My 4 children are now adults - 2 of them are middle aged adults.
I cannot conceive of any situation in which a parent needs to remotely monitor the body temperature of a child. If body temperature changes the child will be "sick" and it will be perfectly obvious.
Unless, of course, the objective is to check if the child is just pretending to be sick 
...R
There is something you can buy off the shelf for location tracking, but it's an ankle bracelet and probably does not monitor temperature.

perfect !!!
so can i use those together?

omg thank youuuu ! such a great advice
I WILL do that . 
Skin temperature is not a measure of core body temperature, so forget using a bracelet for that.
