(again, works fine in python), Code works on my Pi3 B+ however, I dont get live info. import Raspberry_Pi_2 The reason is, that the Adafruit_DHT Version 1.4.0 not yet knows the new Raspberry Pi 4b CPU (may be they will newer do as the Adafruit_DHT library has been deprecated) and recognizes the Pi 4b as a Beagle Bone . We live on a farm. humidity, temperature = read(sensor, pin, platform) Thing is, I have it on a Raspberry Pi 3, where it works without root, and in a Raspberry Pi 2, where it only works with root. Raspberry Temperature Humidity. Doesnt this mean that we get a maximum voltage of 5V on the input GPIO? Managed to solve it, had to increase the delay from 1 micro second to 2 micro seconds. avrdude: stk500_send(): failed to send command to serial port TypeError: this constructor takes no arguments, Hi Interfacing DHT11 sensor with Raspberry Pi to collect Temperature and Humidity data from nearby environment. Like you suggest, I readed some kind of magazines (like the magpi, Raspberry Pi For Beginners or for kids). #!/usr/bin/python It probably something simple, but the entire process has never worked for me. / 5. File q.py, line 7, in Maybe also try with another GPIO pin, to make sure that is not the issue. Can you help me? This is some very basic code written in Python. I got it working but with very strange readings like: pi@raspberrypi:~/wiringPi $ sudo ./example Im getting the same error like you. The DHT11 and DHT22 are fundamentally the same from a wiring and software perspective. File /usr/local/lib/python3.7/dist-packages/Adafruit_DHT/Raspberry_Pi_2.py, line 34, in read I have this error then I try first script in python (without lcd) HOWEVER, if I connect the Arduino to the Macbook directly or via the Mac, I receive the following error: Arduino: 1.8.5 (Mac OS X), Board: Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560), Sketch uses 6900 bytes (2%) of program storage space. return platform.read(sensor, pin) import Raspberry_Pi_2_Driver as driver These will install PIP and other utilities you may need.
