00:00Hey everyone, welcome back to the channel.
00:03If you're building anything with an Arduino, ESP32, or Raspberry Pi that needs to read
00:08temperature, you already know NTC thermistors are the cheapest way to do it.
00:12But with so many options out there, it's easy to grab a dud with a bad B value or sloppy
00:17tolerance.
00:18So today I've done the digging for you, and I found the top 5 NTC thermistors for temperature
00:23sensor projects all dirt cheap, all highly rated, and all linked below. Let's get into it.
00:30Kicking things off at number 1 is this Precision Epoxy Thermistor, and honestly, the name says
00:35it all. You get your choice of B values, 3950, 3435, or 3470, plus resistance values from 5K
00:44all the way up to 100K, and a generous 500mm lead length, which is huge when your sensor
00:49needs to reach into an enclosure or across a 3D printer bed. At just $0.62, with nearly
00:555000 sold and a 4.9 rating, this is the one I'd call the safe bet. Precision plus flexibility
01:02at this price? Easy win.
01:05Number 2 is the budget champion of the bunch.
01:09For only 48 cents, you get an epoxy resin head probe with tin leads and an XH 2.54 plug,
01:15meaning you can plug this straight into a header without any soldering.
01:18It comes in 5K to 100K values with 4 different B value options, so you can match it exactly
01:24to your project's curve. The 4.5 rating is slightly lower than the others, but with almost
01:305000 sold, it's clearly doing its job for a ton of builders.
01:34If you want plug-and-play on a shoestring budget, this is it.
01:38Coming in at number 3, this one's for the tinkerers who like options on hand.
01:43You get 10 pieces of MF52 wired thermistors with 1% tolerance, 10cm leads, and your pick
01:49of 10K or 100K with 3435 or 3950 B values, all for $3.15, which works out to about 31
01:58cents
01:59per sensor. And with a perfect 5-star rating across nearly 4,900 sales, buyers are clearly
02:05happy. Having a pack like this means when one lead snaps mid-project, you just grab the
02:11next one and keep going.
02:13Number 4 is the value pack that makes the most sense for classrooms, prototypes, or anyone
02:18who breaks things like I do. For just 74 cents, you get 20 pieces of MF52 with thermistors
02:24at 1% tolerance, spanning an insane range, 1K up to 100K, all with a 3950 B value. That's
02:32under 4 cents per thermistor, which is honestly hard to believe. Nearly 4,900 sold and a flawless
02:385-star rating back it up. If you're experimenting with different resistance values to dial in your
02:44readings, this pack lets you do it without thinking twice.
02:48And finally, number 5 is the maximalist pick. This 10-pack of MF52 with thermistors covers more
02:55resistance values than any other option here, from 1K all the way to 100K, including oddballs
03:00like 2.2K, 2.7K, and 3.3K, all at 1% tolerance with a 4250 B value. At $4
03:08.88 it's the priciest
03:10on the list, but you're getting 10 precise sensors and basically every value you'd ever need in
03:15one drawer. Perfect 5-star rating, thousands sold, this is the buy once, never worry again
03:21option. And that's my top 5 NTC thermistors for temperature sensor projects. Whether you
03:27need one precision probe or a whole drawer of spares, there's something here under 5 bucks.
