ESP8266 Temperature Sensor with DS18b20

I use a ESP8266 and DS18b20 to output the temperature to the serial output on the ESP8266.

Could explain something to me... How do the ESP82XX modules work? More specifically, say you're outside the range of wifi, does the module create its own wifi signal that you can then connect to, or does it connect to a network and work that way? I'm so confused by this because I see people doing range tests and stuff in what appears to be the middle of nowhere which leads me to believe they're showing the range at which you can pick up the network the ESP module is creating, but then again they could be using a 4G network card/stick or mobile hotspot which would mean the range is directly impacted by the range of the wifi.

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.

Hello
Very tempting, can you share a copy of your basic arduino IDE sketch that get the "reading" from your D1 GPIO pin connected to the data of the probe and injects the value into serial ?

What is the 4.7k ohm resistor between the data and vcc for?

Hi there,

Did you ever produce any videos on how to integrate this into Home Assistant?

[chardos]

Awesome video, such a simple set up. thanks mate

Hi I am new to all this and wanting to have a go at doing same as this for my fish pond but to be able to have linked to my phone is this do able any help appreciate thanks

[glynnmason]

your code doesnt work getting error messages when trying to complie it

[augmentedman]

How would one go about doing this with micropython?

Hi how to publish the data in mqtt server?? Please

Your DS18B20 sensor is too close to the WIFI module, that is the reason why it's warm in the room ;) Move it away as far as possible on the breadboard and you will get more accurate readings.

How do you get 5v from the Vcin of the nodemcu ?
