Temperature Controlled Dc Fan || Heat Sensor

i use a heat sensor to sense the heat around it and use its values to control a opamp which will run a powerfull dc fan

By the way your videos very supeerb because you understand in right way

[@AmitSharma-pu1lz]

Very very nice video fantastic video

[@enesbilge1646]

Hello sir. As far as i understand you set a temperature by using potentiometer and fan tries to cool down the thermistor to that temperature level. What is the temperature range in your project? And what should i do if i want to change the temperature range? It will be super appreciated if you answer sir.

Is it possible to use a BJT transistor instead of the mosfet transistor?

[@Aatikslab]

Yes!!

[@powerelectronics8568]

we can use bjt transistor against irfz44 ?

[@gurpreetsingh3737]

Hi, I have a question, as per your circuit diagram you have connected the pin-2 of LM358 to the thermistor, but as per your soldering layout you have connected it to pin-3. What is the correct one?

[@gurpreetsingh3737]

Also when powered on the LM358 is heating up a lot, any reason why?

[@johnsonnicholaus1874]

What if I need to design automatic design of fan detecting human body followed by temperature controlled circuit?

[@irannahanjagi6584]

Can I use 741 Op-amp instead of lm 358 op-amp. ?

[@mihaichiriac2959]

the speed of the fan is variable ? \

[@khokonmiha5855]

I need circuit diagram

[@dhikasaifulariansyah7326]

what is the function of mosfet

[@konainhaider2397]

Which value did you use the thermistor

[@Aatikslab]

it dosent matter whatever value you use

I need the circuit Diagram please

[@deankay4434]

Click on the “Up-Down” arrow on the right lower corner of the video. In Blue, it will have a link to the basic diagram with the components, pins and other points. I am a retired auto tech and want to control the temperature of a transmission cooler with dc fan on it.
R2 and Thermistor act as a voltage divider input to 2 on OP Amp. With pot on 3, the ability to adjust a small voltage to turn on above or below adjusted point.
Best of luck. Sweet little circuit.
