Getting 'NaN' when I try to read temperatures with DHT11 on ESP8266 with C

Can the Adafruit DHT22 library be modified to support Raspberry Pi 4 Model B (BCM2711)?

QUESTION

Getting 'NaN' when I try to read temperatures with DHT11 on ESP8266 with C

Pictures of the wiring of the DHT11 to the ESP

When I try to read temperatures in Fahrenheit, Celsius and to get the Humidity, it always says 'nan' on the serial monitor. I'm working the Arduino IDE with the Generic ESP8266 Module and I got the libraries "DHT-Sensor-Library" and the "Adafruit-Unified-Sensor"-Library installed.

I know it stands for "Not a number", but why? I looked on here before and tried using (isnan) and store it in a backup-variable, but that didn't work either.

It looks like you're trying to power the DHT11 directly from a GPIO pin.
GPIO pins are intended to send signals. When you use them for power, the results can be unpredictable.

Instead, try powering it from one of the "always-on" 3.3V pins.
If that doesn't work, try powering the DHT11 from an external power source (preferably 5V).
If that doesn't work, please post a picture of your circuit.

Asked 2020-Aug-28 at 05:40

I found the only one Python library for the Digital-output relative humidity & temperature sensor/module DHT22: https://github.com/adafruit/DHT-sensor-library

But considering a function in /usr/local/lib/python3.7/dist-packages/Adafruit_DHT/platform_detect.py it's not supporting the latest Raspberry processor (BCM2711):

I dared to change the above function and it works! But BE CAREFUL if you use outputs that are different for different board versions. I used GPIO4.
