Data logger Gateway + 2 wireless temp sensors
dj_janker last edited by dj_janker
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
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
