Temperature logger

[Kurt]

Hello, I would like to develop a temperature logger which Starts to log temperatures between certain limits
The data is stored until the device has connectivity to the iPhone. It then pushes the Data to the iPhone and the process starts over again. Best would be if radio Connection gets active above a certain temperature. All this should be:

• tiny
• Wireless, i.e. Ble, Driven by cr 2032 3V battery.

Which device should i Take to realize this Project? Is there a dev kit and sample code for xcode available?

Thank you so much for your help,

Curt

Hi Petter, thank you very much for your reply. I asked because I am not sure if it as possible to configure the behavior of the nRF8001. The specifications don't tell about memory, so I don't know exactly if it could log some data over a time to transfer it later on. So if you say I can adapt the functions of nRF8001 to my needs, I would got forward to buy the development kit.

Whereas the 51822 is equipped with everything I need, it is actually not available as a ready to use unit (as i.e. the 8001 you can see here). This would be much more handy to use, but contains only nRF8001.

Thank you again for your advice,

The nRF8001 is not a SoC, you need a microcontroller to utilize it, the microcontroller would have memory to store the temperatures.

I'm not sure I get what you mean by ready to use unit. Do you want to develop your own product or use a ready to use unit?
