Oh mY God, I've never seen such a detailed explanation of this kind of projects. Thanks a lot for sharing a million dollor concept. Thanks Thanks ..thanks a lot Sir 🙏 From India
Thank you for your heartfelt feedback. My channel objective is to ensure sure that topics are explained clearly for everyone to understand with ease. I'm glad you found it helpful 😌 Stay tuned.
Thank you for you detailed explanation. Is it possible to make this bidirectional by adding PTC to the circuit ? in other words if temperature is above 36c turn small miniature motor ( 500ma power) in one direction and if temperature is below 34c turn miniature motor motor in other direction. Also is it possible to use 1M ohms NTC to save power for battery powered setup? I am trying to build little foam window cover to open/or close window for air circulation with air temperature. Thanks
Hi Kosmada, thank you for your feedback, much appreciated. Yes you may use a 1M NTC, all you need is the datasheet information to check its characteristics and start playing with resistor values. Remember PTC are mostly use for over temperature protection, because its automatically limit the current going into the device as the temperature increase its resistance increase. For driving 2 Motors the way you describe it, it does add some complexity in your circuit, you will probably need to you another MOSFET maybe a P Channel. But It will be much simpler to achieve this with an H-Bridge circuit using only one motor, then you can make use of an Arduino to read your NTC and send the appropriate signal depending on the temperature value and which direction you want to run. Let me know, how you gonna go about it.
@@CMTEQ Thank you for your quick reply. With your help I built a circuit simulator with 1 motor , 1 NTC, 1 resistor and 4 MOSFETs ( 2 NPN and 2 PNP) to create a H-bridge.The voltage divider feed all 4 gates and it seems to be working. The change in temp changes direction of the motor. Is it right way of doing it?
Well there's many ways to do it, for an H Bridge to work with an NTC voltage divider point its a bit complicated, send me the schematic you have and I will see it can be improved. Check this demo: th-cam.com/video/qo0tWGgCFb0/w-d-xo.html If you have a twitter account you can dm me the details on @CMTEQ1 or via my Facebook page CMTEQ.

@@CMTEQ I just sent you image via Twitter.
Okay, I will check it out.
can u please share the project file ?
Which project files are you referring to ?
