- In this video you will learn how to Interface DS18B20 Temperature Sensor with NodeMCU. Also we will be building NodeMCU as a web server to display the sensor data. This is a useful and effective project. It is easy to build and can be used at home. You can modify this as per your need.
Parts list:
-------------------------
DS18B20 Temperature sensor (amzn.to/2DeTyma)
NodeMCU (amzn.to/2O0PTus)
Resistor 4.7KΩ x 1
Jumper cables (amzn.to/31QxFUf)
Breadboard (amzn.to/2AHjiqx)
Any Mobile charger 5V/1A as power supply

Just what I was looking for, great tips in the comments below, see Paul Elliott's reply. Thanks for the video.
Nice
Do you tell me Is it possible to control AC FAN dimmer (with zero cross detection) both By two Physical push BUttons (for speed increasing and decreasing) manually and also By Blynk app slider button for controlling speed through wifi.only zero cross detected esp8266 and blynk app slider button based fan dimmer code is available in internet but those are not manually controllable at all when wifi is not available. I ask the question because facing very difficulties to write the code for integrating push button function with only wifi controlled code (By blunk app slider button) . do you know is it possible or not ?
Sir i’ve followed the steps but why it is said that it cant read temperature from my ds18b20?
I followed the step in the the video, but when i try to get the temperature, i'm getting the mensage "Unable to read from sensor".
Sir I'm getting -127 error continuously. I checked all the connections and also resoldered them, but no change.
Only thing is I didn't use breadboard.
Please help me
Hope the sensor data pin is connected to gpio 4 which is D2 of nodemcu

Soldering is the one which makes me to get -127,but when I removed soldering and connected normally
It's giving readings
This does not work the code is bad !! as soon as you access the ip address in a browser the nodemcu crashes with a "panic core_esp8266_main.cpp:137 __Yield" googling says calling the yield function direct is not allowed.. any one know how to correct this please ? this is over my head to resolve.. thank you
paul
Resolved this by installing an old version of dallas temprature library
@@paulelliott2459 Followed your lead and it worked perfect. I want all the hours troubleshooting back. Thank you.
@@jimclark7125 tell me about it... I still don't know what made me try that as a solution 😂
How to fix the output is ......?
Generic board esp8266 error
Plz help
Please share the complete error
Plz check your instagram
Cood danlode nhi ho raha please koi hall baty
Code ko kahan download kar rahe hai?
@@IoTStarters mobile me
@@IoTStarters file bana chta ho
Aapko laptop ya computer pe copy karna hoga, fir mobile pe send kar sakte hai.

Please check the connection properly. The sensor is not connected it seems
