Connecting two sensors dht11 and dht22 the same nodemcu module esp-12e

I have a project where I'need connect two sensors the DHT11 and DHT22 to module nodemcu esp-12e. Is there any way to use the two sensors in the same module at the same time?

Solution

  • If you want an implementation example use steps below:

    • Get DHT library from https://github.com/adafruit/DHT-sensor-library/

    • Use the code snippet below, but do not forget to set your pins :

      #include "DHT.h"
#define DHT11PIN 2
#define DHT22PIN 3

DHT dht11(DHT11PIN, DHT11 );
DHT dht22(DHT22PIN, DHT22 );

void setup() {
  Serial.begin(9600);
  Serial.println("DHTxx test!");

  dht11.begin();
  dht22.begin();
}

void loop() {
  delay(2000);
  float h11 = dht11.readHumidity();
  float t11 = dht11.readTemperature();
  float f11 = dht11.readTemperature(true);

  float h22 = dht22.readHumidity();
  float t22 = dht22.readTemperature();
  float f22 = dht22.readTemperature(true);
  //do print them..
}
