Review on 🌡️ Raspberry Pi DS18B20 Temperature Sensor Module Kit: Waterproof Stainless Steel Probe for Accurate Readings by Vedprakash Trilltight

I had to go through reviews to figure out the correct wiring as it came with no instructions. For those looking to connect to a Raspberry Pi - google the rest, but here's part of it. The latest version of Raspbian (Kernel 3.18) must be added to your /boot/config.txt file in order for the Pi to communicate with the DS18B20. To edit this file, run: $ sudo nano /boot/config.txt If the following line isn't already in this file (if it is, then most likely at the end of the file), add it and save the file. dtoverlay=w1-gpio.gpiopin=4 Reboot your Pi for the changes to take effect. $ sudo reboot To start the temperature sensor reading interface we need to run two commands. Go to the command line on your Pi or SSH into your Pi. Enter the following commands: $ sudo modprobe w1-gpio $ sudo modprobe w1-therm Your temperature sensor output will now be written to a file on your Pi. How to find this file: $ cd /sys/bus/w1/devices
