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 Kurt

Thank you for the explaination. I haven't heard of this before and I'm not aware of any projects in the same direction. The nRF51822 has a 10 bit ADC which can be useful, but unfortunately I can't recommend any implementation. You could create a separate thread addressing this, maybe someone out there has any suggestions.

We have two developing platforms for the nRF51822, the Evaluation Kit and the Development Kit.

The eval kit is a stand-alone development platform with a few 2 buttons, 2 LEDS, coin-cell battery holder, current measurement pins++

The dev kit is used together with the nRFgo Starter Kit which consists two nRFgo motherboards, a display add-on module, and cables. Each motherboard has an nRFgo radio module socket, an add-on module socket, standard interface connectors (USB, RS232, ISP and hardware debug), plus an array of I/O ports and buttons, an on-board I/O controller, and multiple power supply options (USB, battery, or external supply).
