Two temperature sensors DS18B20 on the nodemcu v3

Hi!

I was wondering if it would be possible to have the possibility to connect to temperature sensors DS18B20 on the nodemcu V3 firmware.

Best regards,

@irukard How it works ?

OneWire. Every sensor has unique address.

I tried but I didn’t receive the data from the second temperature sensor in the firmware I use for the luftdaten air sensor nodemcu v3

Should this work, did I make a mistake?

Regards Arjan

I don’t think multiple sensors are supported by firmware.

You will have to modify the firmware to set the second adress or to switch between the 2 addresses.
