It's do-able, but technically speaking, it might not be do-able for everyone.

I'd personally make it from scratch because im good with electronics.

I'd just make a massive computer like board, with all the sensors needed, and run it off the mains (Obviously with a trasnformer)

You just need a thyristor and a humidity sensor and a 555 chip, and the rest if done with timers that you can buy from a shop. Obviously you'd need the right resistors, capacitors and transistors but it can be done.

Theres a few PCB (Printed Circuit Board) design programs out there to download.
LIP Reviewed by LIP on . build ur own climate controller, is it possible? I was pricing out climate controllers online and it really seems to be a pretty basic device. I was wondering if anyone has ever tried to build their own and if it was doable? I'm no mechanical engineer but I know we have a lot of McGuiver's on this board so i figured i'd ask. All it really needs to do is turn on/off certain plugs (fan, c02, humidifier) based on the temp/humidity. thanks for ur input :pimp: Rating: 5
