Hi,

I am having a problem with DS18B20 sensors.
Trying to connect more than 15 sensors but I get 10 sensors of data only.
Used 5v, 1K ohm.
I think the problem is the maximum count of master slave
any ideas to get the all data?

hello
For over 10 sensors is simple. just create a file in wire.conf
/etc/modprobe.d/
You write inside: options wire max_slave_count = 20

Hop and the limit increases to 20 ...

sorry for my english, thank you google translator

I was having same issues so switched to use an i2c 8 channel 1-wire chip. Solved all my reliability issues although it did cost about $15
