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 CIRCUIT DIAGRAM===easyeda.com/Aa...
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.
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?
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.
By the way your videos very supeerb because you understand in right way
Very very nice video fantastic video

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

Also when powered on the LM358 is heating up a lot, any reason why?
What if I need to design automatic design of fan detecting human body followed by temperature controlled circuit?
we can use bjt transistor against irfz44 ?
Can I use 741 Op-amp instead of lm 358 op-amp. ?
I need circuit diagram
the speed of the fan is variable ? \
what is the function of mosfet
Which value did you use the thermistor
it dosent matter whatever value you use
I need the circuit Diagram please

Circuit diagram send plz
its in the video description
@@Aatikslab tnx you ❤️
can you please send the connection details
its in the video description
Can u plz give me the circuit?
Suhail atmose audio its in the video description
@@Aatikslab oooh yes
Thank you
