    hello @shenouda

    have you tried adafruit dht circuit library? adafruit/Adafruit_CircuitPython_DHT: CircuitPython support for DHT11 and DHT22 type temperature/humidity devices (github.com)

    dht22 requires 3 pin connectors (vcc, gnd and gpio), you can use it on tinker edge r

    to install the package:

    pip3 install adafruit-circuitpython-dht --user

    details can be found here: https://github.com/adafruit/Adafruit_CircuitPython_DHT#readme

    Hi @tooz thank you for your reply.

    when I try to do import board i get the following error:

    NotImplementedError: Adafruit-PlatformDetect version 3.40.2 was unable to identify the board and/or microcontroller running the Linux platform. Please be sure you have the latest packages running: 'pip3 install --upgrade adafruit-blinka adafruit-platformdetect'

    i tried running  'pip3 install --upgrade adafruit-blinka adafruit-platformdetect' but still getting the same error. Do you have any suggestion?

  3. Hi I am new to this forum. I am trying to use python-periphery library to use the pins  on the board.

    if I do :

    from periphery import GPIO

    gpio3 = GPIO(3,"in")

    I get the following error:

    Traceback (most recent call last):
      File "/usr/local/lib/python3.7/dist-packages/periphery/gpio.py", line 1017, in _open
        with open("/sys/class/gpio/export", "w") as f_export:
    PermissionError: [Errno 13] Permission denied: '/sys/class/gpio/export'

    During handling of the above exception, another exception occurred:

    Traceback (most recent call last):
      File "/home/linaro/Desktop/temp_hum.py", line 7, in <module>
        gpio3 = GPIO(3,"in")
      File "/usr/local/lib/python3.7/dist-packages/periphery/gpio.py", line 999, in __init__
        self._open(line, direction)
      File "/usr/local/lib/python3.7/dist-packages/periphery/gpio.py", line 1020, in _open
        raise GPIOError(e.errno, "Exporting GPIO: " + e.strerror)
    periphery.gpio.GPIOError: [Errno 13] Exporting GPIO: Permission denied


    Any Idea how to solve this?
