DS18B20+ One Wire Digital Temperature Sensor and the Raspberry Pi. Written by ModMyPi LTD in Tutorials on Apr all data is sent down one wire, which makes it great for microcontrollers such as the Raspberry Pi, as it only requires one GPIO pin for sensing. In addition to this, most 1-Wire sensors will come with a unique serial code (more on

ocumentation gpio GPIO. A powerful feature of the Raspberry Pi is the row of GPIO (general-purpose input/output) pins along the top edge of the board. A 40-pin GPIO header is found on all current Raspberry Pi boards (unpopulated on Pi Zero and Pi Zero W). Prior to the Pi 1 Model B+ (2014), boards comprised a shorter 26-pin header.

WIRE Raspberry Pi GPIO pinout

The Raspberry Pi has several different serial buses exposed on its GPIO (General Purpose Input/Output) pins, including SPI and I2C but there is no 1-Wire interface. In modern Linux Kernels there is a driver module for 'bit-banging' a 1-Wire interface using a single GPIO pin.

Raspberry Pi interface to 1-Wire. There are three primary ways to interface to the 1-Wire protocol devices on the Raspberry Pi: W1-gpio kernel: This module provides bit bashing of a GPIO port to support the 1-Wire protocol. Because this module is not recommended for multidrop 1-Wire Microlans, we will not consider it further.
