Welcome to the OneWireTemperatureSensor wiki!

Introduction

The goal of this project is to serve as an example for how you can use the OneWireIO library to read sensor values off of sensors using the 1-Wire protocol.

OneWireIO uses the Raspberry Pi 1-WIRE bus interface. You need to enable the interface by adding the following line to Raspberry Pi /boot/config.txt file, before rebooting your Pi:

dtoverlay=w1-gpio,gpiopin=x

, where x is is GPIO number used to connect the sensors.

The OneWireTemperatureSensor app is can be read unlimited number of sensors from the Raspberry Pi 1-WIRE bus. Temperature sensors should be connected to Raspberry Pi like is shown in the following diagram:

Here you can see the photo example how the sensors are connected using test breadboard:

After sensors connected and you should list the sensors that your Raspberry Pi has discovered via all 1-Wire buses, using command ls /sys/bus/w1/devices/, like is shown in the example screenshot:

This is a preview of what the OneWireTemperatureSensor GUI looks like:
