5 temperature sensors for arduino projects

If you are thinking about a project that needs to know the temperature, then I've got 5 common sensors that work easily with the arduino ecosystem.

Wanna know more?

This isn't the only way to do it.
It's probably not the best way to do it.

But it's how I do it.

Nice demonstration. I like this format of providing a number of common options available and doing a little comparison. Thanks Kent. Take care.

Fun stuff. My mom has been wanting something to measure the temperature of her house when she travels. I may have to dig through my bins and work something up. Thanks for sharing.

I like the LM35 for temperature at the moment, and the BME280 for temp/humidity/pressure. That was a nice survey of alternatives - thanks Mr Stuff! 👍😀

i was trying to fix a dehumidifier laying arround in my house i was able to read the humidity sensor, the water tank senor except for the temperature sensor which was on the cooling pipes, i was not able to read any data but i came across this vid and it help me out soo well and i could actually read the temps now, thanks once again and i just subbed

Kent love your work buddy.. keep up the awesome content mate.. 🤙🏼🇦🇺

Beer fridge monitor, finally a practical use for Arduino.

Onecircuit mentioned your channel so I came for a look, subscribed and reakky enjoying your videos.👍

A while back I 'instrumented' my waste-water heat exchanger (google GFX gravity film heat exchanger) with one-wire sensors. Four sensors for potable-water in/out and waste-water in/out. Kind of freaked kids out because after reviewing the logs, I could tell that someone got up at 1:40AM and flushed a toilet one night. lol

But seriously, these sort of sensors are great for monitoring whatever you like around the house. I'm thinking about putting some thermocouples on my furnace and hot-water heater flue so I can monitor those next.

Thanks for sharing your information.

For a k type thermocouple you also need cold junction compensation to get an accurate reading. I expect that the chip had that built in? Just had a quick look at the max6672 and it does have the cold junction compensation built in. You also need to remember that if you extend the wires if there is dissimilar metals extra thermal voltages will be added to your signal.

thanks for the links, randomnerds ... looks good

I know this was just the basics, but later you should show using diodes as temperature sensors. Makes for an interesting project.

[jstro-hobbytech]

It's funny how many there are. For 3d printers there's like a page worth of them listed in the marlin source file.

I'm waiting for a bosch BNO055 imu sensor. It cost more than I've ever paid for any one sensor. Adafruit charge over 100cad for their's on Amazon. I slowboated it for around 45 lol

You gotta be careful with some of those sensors that have fiberglass protecting the wires. I got some before where the fiberglass was breaking and the pain that resulted from not noticing and getting the fibers in my hand was brutal, and took days to go away. You could barely tell it was breaking other than the pain that resulted after handling.

[skytaz]

What sensor would you recommend for reading up to 30vdc most of the ones I have seen are only 24v

[matambale]

Time to put some fresh AAA's in the Kaiweets? (Edit: asking for my eyes)

[nertia]

Why does no one talk about the DHT20 sensor? Is there something wrong with it?

[peterferguson]

A friend gave me 3 adafruit trinket..
Has anyone ever did anything interesting with them or found good use for them ?

[AM-jwlo]

Adafruit, dude you need to switch to circuit python and ditch that awful ide. VsCode PyCharm... once you get the repl working you can test the lines of code you want to run (yes on the device) without having to build and export. Watch Scott Hanselman "Hacking an AdaFruit M4 Matrix Display" for someone who tried it for the first time. But thanks you reminded me i have a bunch of one wire temp sensors that i had in a long string and will work great with the esp32 where ever i have one.
