Dht11 Arduino Beispiel

Wemos D1 And D1 Mini Arduino Projects Arduino Projects Arduino Electronics Projects For Beginners

As show in the circuit schematic the dht11 sensor has 4 pins.

Dht11 arduino beispiel. 20 80 5 genauigkeit und im. Vcc 5v data nc not connected pin and gnd from left to right. Void setup serial begin 9600. Void loop wait a few seconds between measurements.

A 10k ohm pull up resistor is needed between the signal line and 5v line to make sure the signal level stays high by default see the datasheet for more info. Arduino dht11 lcd connection circuit. A pull up resistor should be added to the data pin with a value between 4 7k and 10k. The dht11 uses just one signal wire to transmit data to the arduino.

Power comes from separate 5v and ground wires. A beginner tier project i hope will help the fellows that are newbies in the arduino world. Dht11 und dht22 die sensoren dht11 und dht22 bieten die möglichkeit mit dem arduino die luftfeuchtigkeit und temperatur zu messen. In unserem beispiel möchten wir einen dht11 auslesen falls du ein dht22 hast einfach dht22 eintragen definieren der objekte dht dht dhtpin dhttype.

Der dht11 sensor misst im luftfeuchtigkeitsbereich von ca.
