Power comes from separate 5v and ground wires.

Dht11 arduino beispiel. Dht11 und dht22 die sensoren dht11 und dht22 bieten die möglichkeit mit dem arduino die luftfeuchtigkeit und temperatur zu messen. Vcc 5v data nc not connected pin and gnd from left to right. Instantly share code notes and snippets.

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. Dht11 digital temperature and humidity sensor is a composite sensor contains a calibrated digital signal output of the temperature and humidity.

Our interfacing circuit diagram is shown below. Die messwerte können dann über den serial monitor oder einem lcd angezeigt werden. Arduino library for dht11 dht22 etc temp humidity sensors.

Arduino library for dht11 dht22 etc temperature humidity sensors adafruit dht sensor library. Application of a dedicated digital modules collection technology and the temperature and humidity sensing technology to ensure that the product has high reliability and excellent long term stability. Ein kleines beispiel zum umgang mit dem dht11 temperatur und luftfeuchtigkeits sensor.

I published this one since there a lots of various versions of the dht11 library for arduino floating around but most of them do not work with the current version of arduino ide. 20 80 5 genauigkeit und im. Der dht11 sensor misst im luftfeuchtigkeitsbereich von ca.

Nachdem du dein dht11 sensor gemäß schaltbild an dein arduino uno angeschlossen hast kann es schon losgehen mit dem programmieren. 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. A beginner tier project i hope will help the fellows that are newbies in the arduino world.
