I’d like to share a very simple yet interesring project with you: BigClown for homebrewing.
Brewing beer is composed of many steps which require precise temperature control. And as everyone knows, what you cannot measure you cannot control.
I already have a tool for measuring and controlling temperature during mashing phase of the homebrewing but what I lacked so far was measurement of temperature during fermentation. The precise temperature during fermentation is crucial for the success. It affects the flavor of the beer as well as the amount of alcohol in it. And the ranges for the temperature are quite small. For my favourite IPA style is between 20 - 25 degrees Celsius.
I used DS18B20 as the temperature probe. It’s positioned approximately in the middle of the worth. The wiring goes through a hole in the cover. The hole is hermetically sealed so that the beer is not infected. See the pictures yourself:

Temperature development. See the peek at 4pm: This one was actionable because the temperature was growing to high. So I placed the beer to a different room
And after two days
I hope you find this usage of BigClown interesting and hopefully inspiring.
