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.

[@miliohm]

Thanks!

[@shogunvanrepi3555]

​@@miliohm what happens if no resistor is added to the circuit?

[@maxwellvinimax68]

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

[@Alshafi]

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

[@josielsoaresfarias1760]

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

[@mikevez6639]

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

[@rafaellouish.odrada4183]

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

[@user-cf4vo3yv9y]

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

[@gasko2762]

Thank you for the wonderful programs for Arduino for beginners.

[@ajith6840]

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

[@tosc4goro711]

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

[@arthurmarcolan9722]

thank you so much for the help, you saved me

[@Bianchi77]

Nice video, thanks :)

[@GaneshPawar-gs6ee]

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

[@gernandoregobionejunior3794]

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

[@shijumax1]

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

[@Earthstoriesbydev]

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

[@FraLin]

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

[@syukorburger9699]

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

[@raajnivas2550]

Thank you.

[@bradley9856]

good video, but all i get is this in the serial monitor: Locating devices...Found 0 devices. Parasite power is: OFF Unable to find address for Device 0 Device 0 Address: 0000000000000000 Device 0 Resolution: 0 Requesting temperatures...DONE Error: Could not read temperature data

[@jyaniharshil5585]

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...

[@KonselorSekolah1407]

Looks like better than lm35

[@hondat7435]

Hello, can you do one with the VISA LabVIEW?

[@sheenamarietongol4367]

what type of jumoer wire sis you use?

[@chojix6394]

What to do if temperature data cannot be read?

[@BerndJTHIEL]

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

[@spakxd9834]

why on my PC not showing the COM2 window?

[@shogunvanrepi3555]

what happens if no resistor is added to the circuit?

[@battlecampkhimmay2981]

Do you guys have same method on raspberry pi pls

[@raphaelnazareth486]

nice video

[@mend17]

i have an adruino mega were do i place the SDA & de SCL of ic2? couze the A4 & a5 dont work

[@miliohm]

SDA - 20 SCL - 21

[@gouthamas7265]

Hey. I tried the code ,it is working on serial monitor, but when I copy pasted your other coder for LCD ,lcd Is on but not showing anything, need help !!!!

[@AnimeTv-us8gk]

Where did you ordered the tools bro?

[@chandra7734]

is it accurate to measure a room temperature below -10 to -25 degrees Celcius?

[@christophercabanbanalvarad2241]

i followed your diagram and download the code you have posted but still my lcd 168b20 doesn't display anything except for block bars. pls help.....

[@chrisheaps9893]

You may need to adjust the contrast on the back of the display.

[@pearlydanahambayen3939]

My ds18b20 is not giving me results it only shows -127.00c and -196.6f it is not changing even if I put it on hot water can you please help me?

[@jovanadiyatma_6934]

Use resistor

[@TheWareek]

The first sketch worked on my set up but in the serial monitor I got the temperature about every 1/10 of a second. any ideas.

[@mikevez6639]

add delay(1000); to the loop

[@AneeshPradeep]

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

[@miliohm]

What register? The breadboard just help us to put the resistor

[@AneeshPradeep]

@@miliohm Sorry . i meant resistor

[@miliohm]

@@AneeshPradeep it's pull up resistor. It's from datasheet.

[@williampowell7518]

the temperature values that I am getting is not accurate. my room is abou5 celcius but I am seeing 85 degrees Celsius

[@miliohm]

Did it change?

[@TopOneTime]

Can you type the name of the display screen please?

[@pew1472]

im new to to arduino project. why dos it have an error LiquidCrystal_I2C.h: No such file or directory . pls help :)

[@miliohm]

You need to download the library first, watch again carefully

[@chris9yearsago698]

Can you use it for water temperature? Like dip the sensor in it?

[@miliohm]

You should watch at 5:29

[@chris9yearsago698]

@@miliohm thanks man I didn''t actually watch it all

[@Myb.pranoto]

What is the type of the lcd?

[@miliohm]

it's 20x4 LCD

[@wisnuindrawan6496]

how about accuracy is better than themocouple ?

[@miliohm]

Make thermocouple accurate is sometimes complex since it has so small signal. So I think this sensor can be more accurate but, thermocouple has wider range. It can measure up to thousands degrees of celcius.

[@wisnuindrawan6496]

@@miliohm thank you for the answer

[@Imaangrycat]

can i use a 4.7k resistor also i am getting -127° reading what can be my solution

[@miliohm]

It should works, check your wiring again.

[@axel_72]

i have same -127°... but ho to resolved it ?

[@Imaangrycat]

@@axel_72 Check your wiring and make sure that it’s getting proper power supply When I connect this to my esp32 it was not working properly for me but Aurdino uno board gave me proper output

[@xarek24g]

Why u use this resistor with the temp. Sensor i need this one?

[@miliohm]

It's for pull up

[@Saini_Ayush07]

It is a 4.7k ohm resistor

[@chickenz4604]

is the temperature sensor robust for 1 year usage?

[@lovarajukommoju1896]

YES

[@musicalmusician8019]

Is it possible to do this without a breadboard?

[@miliohm]

Sure

[@musicalmusician8019]

@@miliohm Does it require calibration?

[@miliohm]

@@musicalmusician8019 it is factory calibrared. But if you still need adjusment you can also calibrate it.

Can you give me the code of it??plz I need urgent.
