Data logger Gateway + 2 wireless temp sensors

[dj_janker]

Hi,
I newbie at this world and I'm finding info about my project in mind:
I'd like to build a Data logger Gateway for storing data from 2 wireless temperature sensors in a .csv file.

My idea is: Gateway --> Mega+RTC+SD Card
Wireless temperature sensors --> Nano+DS18B20

It`s possible?
Any help, please?

Yes, what you are describing should be fairly straightforward. You could use the receive() function on the gateway to write to the SD card. I would however use 3.3V Pro Mini instead of Nano for the battery powered nodes. See https://www.mysensors.org/build/battery for more information.

For the DS18B20 see https://www.mysensors.org/build/temp
