Dude youre not part of Marvels or DC Comics but just know this, YOU ARE A SUPER HERO

[@sodapop.cigarettes91]

Explanation was straight to the point.Thanks for the useful tutorial! Sensor works :)

[@dphair3805]

Once I changed Thonny from micropython to python3 everything worked like you said. Thanks for the code and explanation.

[@raysrcsandtech]

The only tutorial that worked and was explained correctly :)

[@izzyanalytics4145]

glad to hear!

I already have a Raspbery Pi near the attic from another project (Piaware SDR) and wanted to add another project to it. I was curious to compare attic temperature vs outside. Thanks for producing the straight forward tutorial. It was easy follow.

[@izzyanalytics4145]

Glad it was helpful.

[@yugendravenkatadurgamruthk7797]

Everything worked like a charm. Thanks for a wonderful Video .

[@izzyanalytics4145]

Great to hear!

[@Amine-gz7gq]

Thanks from Tunisia

[@espukiberdy]

Wow thank you so much, fast and understandable

[@sokoloft3]

This would be great to monitor my well house temperature.

[@charleslandis8313]

Thanks! Great info! Have mine up and running. Thanks!

[@izzyanalytics4145]

Glad it helped!

hello what can i do, because whenever i typed cd /sys/bus/w1/devices (enter) then ls the value showed is 00-200000000000? pls help me

[@crashhhhhhh3068]

I have the same problem, and when I type in those numbers in the next step it says no such file or directory. Did you find a solution to this problem?

[@crabsodyinblue]

thanks, fab info.

[@ObsesiontecnologicaBlogspot]

thanks a lot. It's work perfectly.

[@izzyanalytics4145]

You're welcome!

[@Yaswanth_Rayana]

Hello Izzy, the sensor which I am using is not getting registered on the PI. everytime there is a different device name in the "/sys/bus/w1/devices"

[@robertreimann1846]

There was no explanation for the resistor.

[@danielrdugan]

Great video man!

[@izzyanalytics4145]

Thanks!

[@AcvaristulLenes]

Can you connect it to rpi without extension board?

[@osmankhalid2005]

I want to collect temperature and switch off a relay on certain temperature limit. What should be next steps.

[@pubanz8]

Hi, thank you for the video. I would be interested in connecting upto 50 devices in a chain. Is that possible? Will there be congestion on the bus? The conversion time is ~90 ms (upto ~800 ms depending on the bit resolution). Does it mean the cycle time for the whole bus would be 50 times 90ms? Or is there a way to send some kind of strobe / sync signal, so that they would all start their measurement at the same time and than read them out sequentially? Thank you.

[@bonefletch2010]

Can I ask a tutorial on how to incorporate it to Spreadsheet then to SMS for a threshold alert?

[@netsfear4227]

hi there, does its need to be a 4.7ohm resistor or could I use a 10k one instead? (Great video)

[@izzyanalytics4145]

10k should work

[@bonefletch2010]

How can I send notifications to my SMS if the temperature surpasses the threshold? Can you help me sir? :(

[@sfrooze]

Hello, good video, what if i want to connect two sensors for two diferent ambients, is it possible?

[@synonymiumone1003]

I am sending a weatherballon into the statosphere and want to use two sensors to measure the temperature inside and outside of the payload-box :D i just tried soldering the necessary wires and resistors and since it was my first time soldering at all it turned out to be a complete abomination xD But hey, as long as it works

[@izzyanalytics4145]

How it turn out?

[@Jamesb1735]

can this be done with 13 temp sensors?

[@izzudinihsanm.2445]

i can't find w1_slave :(

[@guilhermefranco2386]

Hello, First of all I would like to thank you for the video, it was a great help for my college work. How would I be able to export all temperature readings to a log file, instantly? It could be .csv or .txt. Would you have a code like that?

[@izzyanalytics4145]

Let me know if this is what you're looking for. If not, there are many ways to do this; I can probably put together a few other examples of needed.

[@guilhermefranco2386]

@@izzyanalytics4145 Yes, that's what I'm looking for, but in the video you capture the internal readings of the raspberry, right? I look for how to insert the DS18b20 temperature readings into the open file. thank you for your attention

[@izzyanalytics4145]

It's been a while since I've looked at this, but I believe I did something like that here: github.com/israel-dryer/Raspberry-Pi-Sensors/blob/master/ds18b20_logger.py

[@izzyanalytics4145]

I'm using f-string formatting, so you'll need to have python 3.6+. Otherwise, all you'd need to do is change the f-string formatting to the `format()` method.

[@karejonsson8264]

Is this done with Raspberry 3? Will 3B+ work this way?

[@izzyanalytics4145]

I used the 3b. Should work fine on the b+
