The DS18B20is a very easy to use temperature sensor with the Raspberry Pi.
There are lots of articles explaining how to get things working. Below the way I’m doing it – with reference to the source articles.
A bit of a rough and dirty guide 🙂
Follow process as described in Raspberry Pi 1- Wire Digital Thermometer Sensor
Make the modprobe statements permanent:
sudo nano /etc/modules
add the following lines at the bottom
w1-gpio
w1-therm
and save.
(Reference Adding Modprobe w1-gpio / Modprobe w1-therm to boot)
If required, configure Python:
sudo apt-get install python-pip
sudo pip install w1thermsensor
