Hello everyone,

Ask ko lang if can someone point me where i can find a DIY for temperature contoller that can turn on off my cooling fans? Lalo na ngayon malamig panahon and i think sobra malamig tank ko. Still have to buy a thermometer but isip ko baka meron na puwede isabay ang contoller.

TIA

I asked him about that before. He said it automatically turns on and off depending on your preferences

Di ba overkill kung gamit ko yan for cooling fans ko lang hehehe. La ako chiller.

Kaya hanap ko diy lang baka puwde mag control na mag off kung sobra lamig na. Para iwas temp swings din.

May nahanap ako net puro may adruino. La ako alam sa adruino programming at panu iassemble.

Thanks sir roland and leica for your replies.

pwede ka gumamit ng comparator lang.. may mga simple diy circuits na pwede gawin.. kailangan mo ng temp probe.. pwede sigruo lm35 kaso dapat maayos pag kaka waterproof.. tingin ka na lang thermostat sa mga aircon stores if ever.. or manual mo na lang patayin.. alam mo naman kung kailan malamig or hindi eh.

Best go with Leica's suggestion. Pero di ko sure kung may thermal switch na may sensitivity ng 30C or lower. Sa purpose mo kasi para sa cooling fans eh. Sa DIY LEDs kasi namin, 60C sensitivity nung switch so kapag umabot sa ganung init yung LEDs (for example, nagfail yung fans), shutoff totally yung ilaw. $3 lang yun. mahal pa yun sa lagay na yun.

Anyway, another option would be to use timers instead.

concern ko dn to, lagi naka-on un fan ko
pwede kayang maglagay n lang ng heater? para malimit un temp swing.
mas madali solusyon.
