Raspberry Pi: Luftfeuchtigkeit und Temperatur messen Mit dem Raspberry Pi und einigen Sensoren ist es ohne viel Aufwand die Temperatur zu messen. Daneben kann aber auch die Luftfeuchtigkeit in gewissen Situationen oder Projekten (z.B. einer Wetterstation) aufschlussreich sein. Sensoren wie der DHT11 bzw. DHT22 sind nicht nur für wenige Euros zu haben, sondern können neben der Luftfeuchte auch ... Temperatursensor DHT22 am Raspberry Pi – :: Klenzel Temperatursensor DHT22 am Raspberry Pi Sehr oft wird der relativ günstige Sensor DHT22 (oder auch AM2302) eingesetzt, um am Raspberry Pi Temperaturen und die Luftfeuchtigkeit auszulesen. Wie dieser angeschlossen wird und welche Software dazu verwendet werden kann, möchte ich in diesem Beitrag beschreiben. Wiring for DHT22 Raspberry Weather You can use female and male jumper wires to extend the length of the wires on DHT22 if you bought one without the cables. If you happen to have a white wire, you can leave it disconnected. The second image is meant for those of you that decided to buy the “shorter” version of DHT22. WiringPi auf dem Raspberry Pi installieren WiringPi auf dem Raspberry Pi installieren WiringPi ist ein nützliches Framework um die GPIO Ein und Ausgänge am Raspberry Pi zu schalten. Natürlich ist das Schalten der GPIO’s auch ohne WiringPi möglich (Tutorial: GPIO’s am Raspberry Pi schalten), der Einsatz von WiringPi vereinfacht die ganze Sache aber und ist zudem erweiterbar. Temperatursensor auslesen Raspberry Pi Homeautomation Der Fehler äußert sich wie folgt:. loldht 7 Raspberry Pi wiringPi DHT22 reader .lolware.net Data not good, skip Data not good, skip Data not good, skip Data not good, skip Data not good, skip Data not good, skip Data not good, skip Data not good, skip Data not good, skip Der GPIO Anschluss 7 müsste korrekt sein. Raspberry Pi GPIOs mit wiringPi auslesen und steuern ... Es existieren mehrere Möglichkeiten, die GPIO Ports eines Raspberry Pi zu steuern oder deren Stati auszulesen. Den herkömmlichen und recht umständlichen, oder mit Verwendung der wiringPi Bibliothek. wiringPi ermöglicht die Einbindung in Programmiersprachen wie PHP, Java oder Python. Read DHT11 22 Temperature & Humidity Sensor from Raspberry ... DHT11 and DHT22 are very frequently used in projects that need to measure environment temperature and humidity. They have different range of measurement and accuracy. They have different range of measurement and accuracy. Wiring | DHT Humidity Sensing on Raspberry Pi or ... Raspberry Pi Its easy to connect these sensors to your Raspberry Pi. Our code can use any GPIO pin, but we'll be using GPIO #4 for our diagrams and code. Once you have it working, you can simply adapt the code to change to any other GPIO pin (e.g. pin #18). Luftfeuchtigkeit und Temperatur mit dem Raspberry Pi ... Am Raspberry Pi kann zum Beispiel GPIO 4 (wiringPi Pin 7) benutzt werden. Pin 3 bleibt frei und Pin 4 wird an die Masse, also GND angeschlossen. Das ganze sieht dann in etwas so aus: Pin 3 bleibt frei und Pin 4 wird an die Masse, also GND angeschlossen. WiringPi WiringPi is a PIN based GPIO access library written in C for the BCM2835, BCM2836 and BCM2837 SoC devices used in all Raspberry Pi. versions.
