I am trying to connect to my Arduino Uno board two temperature sensors: DHT11 and DS18B20. The problem is with the DHT11 sensor, apparently there's an error with reading the temperature at every two measurements.

Here's what I get on the serial monitor(temperature 1 is from the DHT sensor):

As I am new to this I was wondering what the problem may be. I have read about the one wire interface used by the DS18B20, but I noticed that the DHT is not using the same protocol.

If I use the DHT11 alone, it works perfectly fine.

Also, I am using 4k7 pull-up resistors for both sensors.

Here's the code:

#include <DallasTemperature.h>
#include <OneWire.h>
#include <dht.h>

dht DHT;

#define ONE_WIRE_BUS 8
#define DHT11_PIN 7

OneWire oneWire(ONE_WIRE_BUS);
 
DallasTemperature sensors(&oneWire);

void setup(void)
 {
 Serial.begin(9600);
 Serial.println("Dallas Temperature IC Control Library Demo");
 sensors.begin();
 }
 

 void loop(void)
  {
 int chk = DHT.read11(DHT11_PIN);  
 sensors.requestTemperatures(); 
 Serial.print("Temperature1: ");
 Serial.print(DHT.temperature);
 Serial.print(" Temperature 2 : ");
 Serial.println(sensors.getTempCByIndex(0)); 
 
 }
