Thermistor for measuring/controlling temperature

[@RimstarOrg]

Thanks. Yes, it's a 3 amp, 240 VAC variac which I bought brand new from a local store many years ago.

I don't think it's a rectangular hyperbola since it looks like when it's near freezing the graph isn't parallel to that axis. I don't know what the fact that it's a curve means. Maybe it's something to do with the molecules or the bonds between them, but looking online I couldn't find any insight. And thanks! Glad you're still enjoying the videos.

[@RimstarOrg]

Hmmm... Now you've got me wondering what's inside those. I'll have to find one and see. I'm glad you enjoyed the video! Thanks!

I just opened up with only PC power supply I have (outside of a computer) and it has SCK 054, an NTC thermistor. I don't want leave this power supply intact though in case I ever need it as such. At least I now know where to find them. Thanks!

[@RimstarOrg]

According to the graph, cold water won't boil sooner than room temp water. Cold water will have a faster heat transfer rate while it is still cold, but once the cold water reaches room temp, the heat transfer rate will be the rate it should be for room temp water. So once the cold water reaches room temp it will take the same time from then on as room temp water does.

[@RimstarOrg]

Thanks again Dan! I've done likewise with your recent solar key making video. I love how it's something so practical.

This week's video is an electronics one all about using thermistors, what they are and how use them to measure and control temperature. I especially had fun doing the simple circuit where I heat up the thermistor with a hair dryer until that causes the fan to turn on. And then the fan cools off the thermistor, causing the fan to turn off!

Super cool. Content is clearly understood even after 7 years and am sure that my statement will hold good after another 7 years too.!!!

[@RimstarOrg]

The only way I know to do that is create moving positive ions. It'd be atoms that are ions with positive protons and neutral neutrons in the nucleus and negative electrons surrounding the nucleus but there would be less electrons than protons, and so they'd be positively charged. In fact, I've done it in my "How to Make/Build a Lifter or Ionocraft" video. The positive wire electrode strips electrons from atoms in the air to create positive ions, which flow down to the negatively charged foil.

[@user-be4yc2vr5c]

Comrade thank you, I can't believe I couldn't find anything online when I typed in "thermal protection resistors" or "thermistor" even only came back with typical temp. measuring therms, not resistance regulating ones.

[@RimstarOrg]

Good point. Though I don't know how much mine can handle since I couldn't find any specs on it at all.

[@RimstarOrg]

This sensor is for attaching to the cooling system in a particular model of car, so you'd have to make your own mounting system. To turn on a fan below 100C you can do what I did in the video. But it probably won't turn on at 100C. For that you'd need to add a resistor so that the total resistance adds up to something that would result in the right current for the fan. You also have to consider what temperature the fan should turn off at. Search google for "pexsupply snap disc" for a better way.

[@RimstarOrg]

An IR gun, one of those handheld infrared guns that you point at things and then the temperature is shown on a digital display would work.

[@Slider2732]

That was fun :) Just grabbed what I thought to be one off an old PC power supply and had a little look. Green disc 'SCK 2R55A'. Thought may as well try it. Only 2.7ohms at 80F room temp. Held in hand it went to 2.5ohms, in front of a small fan, up to 3.3 ohms. At 10x those figures it would be similar to your automotive one...did a search and it is one, but nothing like as variable as that one you show. Still, I now know something more about them, cheers.

No need to do the setup with common resistor. I just connected a 1 kohm, 2 watt resistor to my meter and put the same hair drier on it for 1 minute, twice as long as I did in the video, and the resistance increased by only 8 ohms. Common resistors aren't affected by temp. as much as thermistors. The VARIAC is a 3 amp, 240VAC one which I bought off-the-shelf. I'd recommend higher amperage for more usefulness. Maybe salvage from old power supplies but usually buy second hand since they're costly.

[@DerLeeker]

Great explanations... and was this red thing ,which you switched on, a variac?

[@RimstarOrg]

It isn't a capacitor symbol, though I can see the resemblance. It's supposed to be like two walls facing each other. When they're close together they restrict the flow of electrons i.e. high resistance. When they're farther apart they allow more flow i.e. low resistance. Oh well.

[@DigGil3]

Speaker and Microphone, LDR and LED, Fan and Thermistor: feedback systems galore! You could have mentioned that most common resistors also behave somewhat like thermistors. Interested on repeating that setup and comparing the curves? Also, I've been noticing your nifty-looking autotransformer. Do you mind giving details about it? Might it be salvaged from something I could get my hands on?

Thank you for your video! I have an off road buggy and the fan isn't switching on to cool the engine. It looks like it's the same type of thermistor so I'm going to check the resistance now and see if its working!

[@Slider2732]

Found a great one just now. Take a look for small green bulb type devices attached to back of large heatsinks. Got one from another PC power supply, it was 7.3K at rest in approx 80F. Blew on it for 30 seconds and it went to over 8K, warmed it between fingers and it went down to 6.5K. Can only imagine fridge and sun values...pretty good temp sensor for free, once calibrated. Perhaps to keep an unpowered eye on transistors or other circuits, or part of indoors/outdoors actual temp sensor :)

Is there a way to directly measure the temperature of the thermistor to know how much heat/resistance it requires to allow current to the fan?

[@oreidjm]

[@samerawaragi3041]

Thank you for making this video. A small question is how to know if a thermistor is malfunctioning? In my car A/C, the compressor cycles soo much and especially in cold weather. When I jumped the connection; it stayed ON. It is trying to control the temperature to 4 degC but it seems too sensitive. Is thermistor can go bad or is it a design flaw in the circuit? thank you for your video.

[@RimstarOrg]

I guess you'd have to isolate the thermistor from the rest of the circuit and then create a setup like I have in the video. Then set up a test circuit like I do in the video and see if it works. Or if you can't remove it enough from the circuit then try heating it with a hair drier.

[@RimstarOrg]

And I'm glad to hear you liked my video. Thanks for watching.

[@phaniraja9104]

which sensors are used in mobile phones for temperature detection ??

[@sachinsherry8175]

Can you please tell me the specifications of the thermistor featured in this video

[@RimstarOrg]

I don't have any of the specifications for this thermistor since it's embedded in the automotive sensor. The info for the sensor is BWD 020-7913-8 WT691 but that probably won't help you much.

[@sachinsherry8175]

+RimstarOrg I just wanted to make a project on a thermally controlled fan just like you did for fun

[@iadt5047]

hey, the idea is just awesome...but upto wat temperature does this system works or upto wat temperature will it sense the temp/.....

[@RimstarOrg]

+iADT I don't know. There's no data on the box that it came in and I wasn't able to find a datasheet for it online when I looked before. Maybe you'll have better luck. It's a BWD part and the part numbers on the box are 020-7913-8 and WT691. It's normally used for car engine systems somewhere. But if you have a non-automotive thermistor, one that isn't in the brass casing like mine, then you can probably look up some numbers online.

[@riccardogiuffrida9632]

very good! but I have a question: what temperature reach the thermistor 1 k ohm when you apply 12 volt? it is very hot (about 85 C) and isn't dangerous if you put it in a fuel tank to have a low sensor that light a bulb? sorry for my poor English. Ciao.

[@RimstarOrg]

I don't know the answer for your first question. For 85C, search for the "ignition temperature" of your fuel.

[@tastyfish4890]

Does the thermistor have a maximum current limit to it ? How much current can it handle before it breaksdown ?.

[@RimstarOrg]

+Tasty Fish Mine didn't have anything written on it, probably because it's an automotive sensor intended for certain cars. Looking at some datasheets doesn't help much either. From en.wikipedia.org/wiki/Thermistor "If the current is large enough to generate more heat than the device can lose to its surroundings, the device heats up, causing its resistance to increase. This creates a self-reinforcing effect that drives the resistance upwards, therefore limiting the current." So it sounds like the answer is no.

[@tastyfish4890]

+RimstarOrg Thank you mr scientist .

[@Beykoz1]

I have a question for you , i gotta remote controlled car motor and i would like to place my custom fan for cooling which would be controlled by a NTC Thermistor. But i am a little bit confused about the temperature that i want it to turn on. Do you mind to help? I was thinking to M35 or 5D-11 would work. the heat goes on those brushless motors pretty high sometimes. I would like to find the right thermistor that it would turn on the fan around 150-175F. which model thermistor should i use do you think?

[@RimstarOrg]

I couldn't find any data on the M35. The 5D-11 has the temperature range.

[@GlobalAwareness2525]

My Whirlpool gas dryer isn't getting hot enough and the clothes never get dry, the gas flame works, it's just shutting the heat off too soon, so I bought what is called a thermistor in a sealed plastic case that screws onto the exiting chamber after the blower. This did not solve the problem. When I remove the thermistor as to not allow it to sense any warm temperature and left it plugged in the flame stays on endlessly. At first I assumed that even though the encased thermistor was new in the package that it might be defective straight from the manufacturer, but now that I see this video there are a few of these disc-like thermistors attached inside the dryers wiring harness, they are not seemingly positioned in any specific spot as if to sense temperature, but just part of the wiring, I always thought these were perhaps some sort of resistor, but instead they are identical to what you call a thermistor. When I was at a dead end on what to do next then this video helped me to decide that the next thing I should try is to replace the short harness sections that contain these thermistors. Thanks for making this video.

Very good video

I want to build a circuit to trigger a buzzer if the temperature in my fridge gets too high. I lost a bunch of groceries after an electrical snafu in my home and wanted to prevent that from happening again. Do you have any other videos which might help me understand how to design a battery supply which only began to feed power to something should another power source fail? I suppose I just want to learn how to design a portable back up battery. Portable as in I can easily carry it from one place to another and portable as in it could be easily adjusted for use with most DC supplied electronics.

Have you done a vid on esp8266 12e to 10K Thermistor?

[@RimstarOrg]

No, I've never even worked with the esp8266, though I should someday. It's very popular.

[@Batman-ft9nk]

thank you for the help

great video.

[@neilmac991]

Very thorough

[@jv1zz]

Does anyone know where i can get a temp sensor that turns on fan at 95 degrees no matter wat

[@botin818]

very good theory

Hi Thank you for your great help. I have a dishwasher thermistor on which T120K carved. I do not know how to find resistance vs temperature. Would you please help me?

[@RimstarOrg]

Hi You can use the technique I show in this video. Alternatively, you'd need a part number for it and then to search online for that part number and hope you can find a specification sheet with a resistance vs temperature chart.

If you're going to use a thermistor to control more than small power then use it to control a power transistor (a FET or Darlington) that the power flows through.

[@orionarts8478]

I would like to use something like this to turn on and off an electric pvc sprinkler valve. On at 65 F, off at 75F do you have any suggestions?

[@orionarts8478]

or visa versa

[@RimstarOrg]

+Jonathon Shafer You could use a circuit with a thermistor, that's in the right range. Or you could try looking for a snap disk (rimstar.org/equip/temp_control_circuit.htm), though those temperatures are a little low for that.

[@orionarts8478]

+RimstarOrg it is to regulate water temperature inside a large tank for fish...if that helps with ideas. I want to recycle the water from an underground collection tank also using the home hot water to balance temperatures.

[@Ex-fk4nr]

how do you set a threshold for example when the thermistor reaches a certain amount of temperature the fan gets turn on....thank you?

[@RimstarOrg]

That's up to the thermistor. When you shop around for one, you look at the specifications to see what temperatures it works with.
