Dht11 Arduino Beispiel

Arduino dht11 lcd connection circuit.

Dht11 arduino beispiel. Der dht11 sensor misst im luftfeuchtigkeitsbereich von ca. Vcc 5v data nc not connected pin and gnd from left to right. A beginner tier project i hope will help the fellows that are newbies in the arduino world. Dht11 humidity temperature sensor with 16x2 lcd display project showcase by onatto22.

Void loop wait a few seconds between measurements. The dht11 uses just one signal wire to transmit data to the arduino. As show in the circuit schematic the dht11 sensor has 4 pins. A pull up resistor should be added to the data pin with a value between 4 7k and 10k.

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. In unserem beispiel möchten wir einen dht11 auslesen falls du ein dht22 hast einfach dht22 eintragen definieren der objekte dht dht dhtpin dhttype. Power comes from separate 5v and ground wires. 20 80 5 genauigkeit und im.

Dht11 und dht22 die sensoren dht11 und dht22 bieten die möglichkeit mit dem arduino die luftfeuchtigkeit und temperatur zu messen.
