DS18B20 Temperature Sensor Tutorial

DS18B20 Temperature Sensor Tutorial.

In this video we are learning about DS18B20 temperature sensors. ds18b20 is a temperature sensor with a decent temperature range and Accuracy.

Amazing Device for data logging.

Measures temperatures from –55°C to +125°C (–67°F to +257°F)
±0.5°C accuracy from –10°C to +85°C

Unique 1-Wire® interface requires only one port pin for communication. Each device has a unique 64-bit serial code stored in an onboard ROM.

Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system

Thanks for the Info. got my new DS18B90 up and running in less than 20 minutes. Had to watch your video a lot you are very fast.

I have being all over Youtube looking for the most simplest DS18B20 Celsius to Fahrenheit conversion code ever for a beginner like me, without having to go to Canada via the UAE coming from the South Pole. Thanks for you video

Thanks Dude, you made this super easy to understand.

Been looking for a description like this all day.

Hi,

I've been trying to get this to work for ages. Many many thanks.

straight to the point and helpful. liked 3 times

thanks . i also showed how to get data from ds18b20 using normal usb ttl adapter, without using any microcontroller. may be that might be of your interest.

The display of negative temperature is not treated.

Please make video on, how to connect 10 (ten numbers) humidity and temperature sensors with Respberri Pi or Ardiuno. And important is these sensors having 150 meters lengthy cables. Please make detailed video thanks in advance.

Nice Vid! But I'm worried about the resistor leads touching the other pins. (0:37)

Hey super helpful video! So I am trying to use DS18B20 to create a breathing monitor. Where do you think is the best placement for the DS18B20 sensor to measure temperature change when breathing?

[DrewyJin]

Is it reliable to use this temperature sensor to measure body temperature from the finger tips? Im working on a portable health monitoring system and ease of temperature taking is one of the concerns...

This sensor will give us result only when it is in contact with air or
else it will give us reading in hot or cold water also??
Does this sensor requires some initial readings to display temperature on dashboard ???( like minimum temp is -55 and max is +125 so in-between of this it will calculate all the readings ? )

hi, i wanna ask you, what do you mean by pull data down or up when you answer one of these questions, and what we mean by interface wire using in that sensor?

[BGLENN-dptx]

It is not very good electronics protocol to jumper the 4.7k resister across the top of the breakout board. Put the resistor to an empty breadboard hole and use an insulated wire. As can be seen in the video image @ 1:10, the resistor wire is dangerously close to shorting out D12 to both D11 and D10 - all together -- not to mention shorting A4 to Vcc on the other side of the board. If you must route a resistor in this way, strip a section of insulated wire and use the insulation over the wires of the resistor. These precautions will save hours of frustrating software troubleshooting on a board that has a couple of bad/zapped pins due to momentary misconnections/shorts.

Hi there, Could you please let me know how to connect the DS18B20 to a BeagleBone Black and get the temperature reading please?

[ErdosainNueve]

Hi. i see a lot of diagram with gnd and vcc together to GND and the resistor on data, from there one to data and other to 5v. Can you tell me why?? (i dont speak english)... why you connect resistor between vcc and data?? its because the lenght of the cable?? like 1m. I know that is possible doing in anyway, in both ways. but why?
Thanks and sorry about my bad english.

DS18B20 Temperature Sensor is not IP6, right?? Can we use it under water or under very harsh corrosive environment filled with gases?

[arunpatil]

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??

[docturek]

Hi, when I want to use three waterproof DS18B20 sensors, which resistor should I use? Thank you
