I’m working on a project to improve the control of temperature between wood boiler (built in house) - 500 liter tank - solar collector-intercooler from the exhaust of the boiler temperature and other controls that have need of a lot of temperature sensors .The project starts from the lessons learned from differduino by nateful.com
I had to add an electromechanical bypass the wood boiler (inarestabile with fire lit) for frequent failure sensors DS18B20. The system works so incredible solves the problem of hot water and heating a house of 150 square meters with climate of northern Italy
I tried everything found to solve the problem and now I got to the end of my confidence, and I want to try and 2wire i2c sensors LM75 arriving from China in a month.
If anyone has knowledge of these sensors placed parallel on 2wire thank him for the time you’ll want to devote.
