DTH22 & DS18B20 conflict


I am building an aquarium controller and I am facing problems for getting correct temperatures from my four DS18B20 temp sensors when I use the DHT 22 also can it be there is a conflict with both libraries maybe someone else faced this before .

If I only use DS18b20 in my sketch I get proper temperatures but with The DTH22 also included I get correct temperature and Humidity from DTH22 while on the DS18B20 i get 85.00 from all four sensors.

the libraries I am using are below.
#include “DHT.h”

#include <OneWire.h>

#include <DallasTemperature.h>

Any help is highly appreciated

Please post your complete sketch, and in this case also the schematic.

The 85C is a value that the DS18 has not been initialized properly, so I assume there is a problem with your poser supply.
All sensors in total might drop the 5V. Can you verify with a Digital MultiMeter?
