Dht11 arduino beispiel. Arduino dht11 test ino dht11 test sketch mit der dhtlib. As show in the circuit schematic the dht11 sensor has 4 pins. Beispiel wie die arduino dhtlib eingesetzt wird.

Ein kleines beispiel zum umgang mit dem dht11 temperatur und luftfeuchtigkeits sensor. The dht11 uses just one signal wire to transmit data to the arduino. 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.

Nachdem du dein dht11 sensor gemäß schaltbild an dein arduino uno angeschlossen hast kann es schon losgehen mit dem programmieren. A pull up resistor should be added to the data pin with a value between 4 7k and 10k. Der dht11 sensor misst im luftfeuchtigkeitsbereich von ca.

Power comes from separate 5v and ground wires. 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. 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.

A beginner tier project i hope will help the fellows that are newbies in the arduino world. Working version of the dht11 library for arduino. Our interfacing circuit diagram is shown below.

Die messwerte können dann über den serial monitor oder einem lcd angezeigt werden. Dht11 digital temperature and humidity sensor is a composite sensor contains a calibrated digital signal output of the temperature and humidity. Vcc 5v data nc not connected pin and gnd from left to right.
