- Hello guys, Welcome to Robocraze! In this tutorial, we'll show you how to use the DS18B20 temperature sensor with the ESP32. We'll cover the basics of the sensor and how it works, then guide you through setting up the ESP32 and connecting it to the sensor. We'll also walk you through the code, including how to read temperature data and display it on the screen. With this tutorial, you'll be equipped to start creating your own temperature monitoring projects.

the only one works, thanks!
Hello,
Glad you liked our video! please subscribe to our channel for more interesting and innovative videos.
What is the maximum length from sensor to nodemcu for it to work properly??
Hello,
Longer cables experience voltage drop due to resistance. Ensure sufficient voltage at the sensor. So cable length can be tested by seeing if there is any voltage drops.
Please, how do you connect the DS18B20 sensor cable with the source cable?
Hello,
DS18B20 ESP32
-------------------------
VCC (Red) -> 3.3V
GND (Black) -> GND
Data (Yellow) -> any gpio
4.7k Ohm Resistor between Data (GPIO) and 3.3V
Thank you!
is it possible to get the code for the setup but we are using the arduino uno wifi r2
Hi,
The code is avaialble here: github.com/Robocraze/DS18B20
At 5:40 can’t you use the 5v pin of the ESP32 Itself, rather than bringing a whole another microcontroller ?
Hello,
The ESP-32 module does not have a dedicated 5V pin. Instead, it operates at 3.3V.
How to key in temperature on thingspeak and act on the set temperature?
Could you please clarify? You want ThingSpeak to act on it, or the ESP32 itself?
Is it possible to not use Arduino Uno Board, just the esp32?
Yes, it is possible to use the ESP32 board without an Arduino Uno. The ESP32 is a standalone microcontroller board that can be programmed using the Arduino framework.
@@Robocraze yeah I'm confused, why did you connect an arduino to it instead of just using the ESP32 ?
so how come you went to the Math website?
What was it used for in this instance?
Hi!
ThingSpeak is an IoT platform built by MathWorks. We are using it to upload the values/readings from our Temperature Sensor to their Cloud.
@@Robocraze I'm not sure it's integration was displayed within the video though
Hey, can i do this on esp32?
Hello,
Yes, this is done with an ESP32.
eska code do na
You can find the code in our blog, link to which is given in the description. You can also find the code hosted on our github repo here: github.com/Robocraze/DS18B20
