learn how to use DS18B20 temperature sensor with Arduino mega/UNO/NANO.
The DS18B20 temperature sensor is a 1-wire digital temperature sensor. This means that you can read the temperature with a very simple circuit setup. It communicates on common bus, which means that you can connect several devices and read their values using just one digital pin of the Arduino.

hiee bro i need your help. I am using this sensor, for the first time it worked perfectly but after that, I had cut the wire to solder jumper wires but after soldering it is showing -126 degree celcius only. How to resolve this??

[ali_youtube_user_]

I dont understand, why do we connect the resistor terminals from the Vcc to the data line ? Why not from the arduino gpio pin to the data line ?

Hi Guys, i unable to get the result....it still on
-127.00 C -196.60 F
-127.00 C -196.60 F
any idea?
I had try to get to changed all the cable and resistor...

[tugasakhirhendro]

what is the difference between sensor DS18B20, DS18S20, DS1822, DS1820?

[topfundus]

Sehr gut! Funktioniert alles. Vielen Dank!

[tamgaming]

Thanks a lot for your video! Why do you need a resistor and how do you calculated how high he has to be? Thanks in advance :-)

[beebzyful]

Is there a way to use this sensor with an arduino one wifi rev 2 board? I could really use help with this

[gameeducation]

Hello.
you putted data wire into digital output pin....
but data wire should be connected with analog input...!!!

[arthurberkouwer]

The video looks nice, but where can I download the code?

[abanjhfj]

But if i use a grove arduino and not a breadboard where i connect the resistor ? please

[KhianVictoryDCalderon]

Bro is the resistor between positive and analog pin?

[SashiRockzz]

How many temperature sensor can be connect to this arduino????

[muhammadalfian]

can help me, how to make this with two multi sensors? please..

[emilep.]

Thank you very much for this tutorial, it helped me a lot !!

[ivanmartinez-omlq]

Hi, I´m running the code, and it´s working, but my temperature began at 50 C, and is increasing, without heat... my environmental heat is 18 C. Can it be the resistor? The sensor is heating increasingly. Thank you!

I have been using Arduino 1.8.5 for Windows 8 for years now without any problems.

I followed the instructions in this video and that's the last thing I ever did with Arduino, now it won't start whatever I do.

I even tried uninstalling completely and re-installing the exact same version of arduino for IDE but the problem persists.
Is anybody else having the same problem?

Because of the problems I am having with arduino right now, I say be careful, make sure you can backtrack to the current
state where you computer is at before trying.
When I run arduino_debug what I am getting is shown below:

C:\Program Files (x86)\Arduino>arduino_debug

[warrenwalter]

your code is full of mistakes - not including { and therafter using } etc. frustrated now cause im trying to learn !

[choichifaijasonccf]

It keeps showing -127.00 C and -196.60 F
any suggestion?

How to on off light with arduino when temp high low For incubator can u show that???

[rajipanicker]

Hi If its is aurdino mega
how do i connect the wires
