Readings, some times my project works great,so i dont think its a code issue

Solved

I have 4 DS18B20’s and 1 DHT11 along with one push button.
Sometimes the DS18b20’s read -196, and the DHT11 will read zero and the push button will be on.
sometimes this is only for a second or two, other times it will be hours.

Any ideas as to why? Right now it all on a bread board, want to work it out before coming up with a long term
hard wired project.

Thanks for any input,

If you don’t think it’s a code issue there are few options:

  1. Breadboard connection.
  2. Power supply issues
  3. Knockoff components

if you use too many DS18B20 on the same board,it will goes wrong.
