I follow ‘Speak to the Geek’ on YouTube and one of his projects was to control the speed of a fan based on temperature, this blog is how mine ended up.
Full credit goes to ‘Speak to the Geek’ and his homepage where a full description of parts and build are HERE.
The reason this tweaked my interest was to try and maintain a steady temperature in my home IT cabinet and it works with Home Assistant.
My current cooling arrangement has fans which simply trigger on high temperature, hopefully this will smooth out the ‘on – offs’.
I had a spare ‘Room Sensor Enclosure‘ which I bought from The Pi Hut which everything managed to fit inside.
The 120mm fan will turn on at 28oC at a preconfigured speed of 25%, as the temperature increases, so will the fan speed, reaching full speed at 31oC.
So far it is working perfectly 🙂
