How to use DS18B20 Temperature sensor with arduino

DS18B20 is one of the popular temperature sensors because it is cheap, easy to use, and also waterproof. It is a very cheap waterproof temperature sensor we can get from the market.
In this video, we will learn how to use it with Arduino.

I've check the code you gave that is so detailed, to be a primer I learned a lot from it, I'll be guilty if I dont hit a like on this video.

what all u said worked out perfect.first i thought my display had prob then changed contast and wroked perfect. never thought i will be able to something llike this for my school project. thanks man

[toscgoro]

thanks a lot for the tutorial sir, could u also make the one wire version tutorial of this sensor? thanks!

[Alshafi]

Thanks for the vid. i would only recommend installing the OneWire library since it is actually required in the example.

[AirisSafiyyah-nd]

Hi, can you list all the things that you use for making this temperature sensors?

[ajith]

Thank you so much for this video👍
Is it possible to add an battery voltage sensor along with the temperature sensor in the same Arduino, How can we combine the both programs

[Earthstoriesbydev]

have u done this with a battery? What battery it might need do u know?

[rafaellouish.odrada]

good day would like to ask why my serial monitor shows the device cannot be found that show error results

[mikevez]

If people are getting strange results disconnect the power line to the sensor if using parasitic power from the arduino. just run 5v thro the resistor to the signal wire in yellow. This is what the datasheet says

Valeu amigo. Ótimo vídeo
Único vídeo que encontrei na internet que realmente explica como faz. Parabéns e Obrigado. Ganhou meu like 👏

I was looking for polarity and colours, can it die if I confuse yellow and red?

[shijumax]

Hi, I am your new subscriber, can u make a video or explain to build a SMD reflow with Nextion display?

[GaneshPawar-gsee]

can we add more than one DS18B20 sensor wire on same bus/pin

[gernandoregobionejunior]

Hi, i'm having some problems with this sensor when i try to heat the water until it evaporates, my sensor can't read a temperature above 100°C or equal. My programation sketch is similar

[BerndJTHIEL]

how much of this sensors you can use parallel on a androinu? i need a system with 8-16

[AneeshPradeep]

What is the purpose of the register
Can the sensor be connected directly to the board ?

[jyaniharshil]

Hey brother can you tell me the code for my project . ds18b20 temperature sensor, LCD 16×2, arduino UNO & fan, all connected .

As the temperature rises, fan goes fast or Start rotating and if temperature goes low, fan slows or stops down...

Thank you for the wonderful programs for Arduino for beginners.

[arthurmarcolan]

thank you so much for the help, you saved me

[syukorburger]

hey, why my (tempC != DEVICE_DISCONNECTED_C) at line 56 is error, it said "'DEVICE_DISCONNECTED_C' was not declared in this scope" i hope u can help me with that
