I am having trouble getting to run my temperature sensor. If I execute the following script to check if the PIN 7 gives me an output, it returns 1 (as it ought to).

import re, os, urllib2
import RPi.GPIO as GPIO

if __name__ == '__main__':
    GPIO.setup(7, GPIO.IN)

    print GPIO.input(7)

Furthermore I am VERY sure, that the setup of my temperature sensor is correct, you can see an image of it here:

As it goes into the GPIO ports, the wires are arranged like this:

For all of this I was using a Rasperry Pi 3 Model B V1.2. My kernel Version is 4.4.50-v7+ As Operating System I am using Raspbian 8 (jessie)

Could it be a hardware, or a software error? I also changed up all the files as you see it in various tutorials (see comments) but still it doesn't show up in the w1/devices folder. Please help me, I have no idea what I could have done wrong. If you need further information feel free to ask.

  • I used this tutorial: golem.de/news/… – Cowboy_Patrick Aug 6 '17 at 12:20
  • I watched the video on the tutorial website you mentioned. Something is missing on the video of your reference tutorial(Since I don't know German I watched the video). The following link will be helpful for you to configure DS18B20. pimylifeup.com/raspberry-pi-temperature-sensor . Also adafruit lesson written by Dr. Simon Monk is also very helpful for your project(following link). drive.google.com/file/d/0B5HkM_BeqkJxSi13aExqT1AwZVU/… – Arun K S Aug 7 '17 at 14:38
  • thank you very much! Hope these links help. You can also watch another tutorial if you want, I'm sure they just copied it from an english source – Cowboy_Patrick Aug 7 '17 at 14:43
  • I think problem is with configuration of your 1-wire protocol which is not mentioned in the tutorial you referred. To know more about 1-wire protocol configuration for ds18b20 read pinout.xyz/pinout/1_wire this one too. – Arun K S Aug 7 '17 at 14:50
  • Oh yeah I will! After a little debugging I'll tell you wether or not it helped😉 – Cowboy_Patrick Aug 7 '17 at 14:57
