hello everyone!!
i want to make hardware system which is to control AC fan based on temperature..i used lm 35 sensor..is it someone have the coding about that?i want to do some experiment..
thanks for helping... :-/

thanks richard!!very helpfull..

this is the specification of the AC fan..

model:AVS-1238
size:120mmx120mmx38mm
230v~AC50/60Hz 0.13A..

I would use a SSR (Solid State Relay) to control the fan. hey have an optical isolated input so that means if any mains gets mixed into your arduino it's your fault.

SSR is probably BETTER, and NOT HARD, but if you want something even simpler, more new-person-friendly, there are also relays....

Be very, very careful with the 240v (or 110v, for other readers) side of things. Best to have what you plan to do checked by someone who knows the "tricks" it can get up to before you start to build something which might need re-design to avoid real... and not "obvious"... possibilities for fires or deaths. (That warning applied even if you use an SSR)

so..is there need any coding to control and solve the problem..i am sorry because i'm really new..hope u all can help..

Do you need to program the Arduino to read a temperature sensor and turn a fan on and off?

Yes.

See....

... for a course in Arduino programming.

Turning a fan on and off is just the same as turning an LED on and off as far as the programming is concerned. It is just a matter of setting a pin high or low.

so..is it the coding to control the fan whether on or off is same the coding to turn the led on and off Grumpy_Mike?
