PROJECT DESCRIPTION

created by Jesse Davids.

This project features multiple ds18b20 temperature sensors, all on a one wire bus. All sensors are identified by their unique serial number, accompanied by their sensor value. This data is sent to a web server, posted as JSON on a webpage. You can retrieve the data sent to the webpage into your network management software, graph it out and boom. Done.

What you need to consider

This repo supports only the DS18B20, other sensors have not yet been tested. You can feel free to do so.
You will need a pull-up resistor, i used a 5K ohm resistor.
Alter code to use up to 18 sensors.
