Hi all!

I managed to read data from my DS18B20 using Particle Photon using this tutorial:

How can I hookup and read data from two sensor instead of one?

Thanks!

Dallas temperature sensors are designed to be connected together in a bus, because most micro controllers use 'bit banging' to communicate they are often limited.

Your best bet is to use a actual bus master look at the data sheet to find a compatible part

I purchased a few of these for about a buck each off ebay
