- Learn Sensor Monitoring using Blynk Mobile App and NodeMCU ESP826. In this lesson, we’ll interface the LM35 analog temperature sensor with ESP8266 NodeMCU. And later on, through blynk web dashboard, we’ll create a template. This template is further used to create blynk mobile app for monitoring live temperature sensor data. This step-by-step tutorial will work even when you have a different microcontroller.
0:52 Create blynk template
6:05 Write program for NodeMCU
9:04 Setup temperature sensor circuit
12:40 Monitor sensor in web dashboard
14:40 Create and modify blynk App
17:10 Monitor temperature live

Another great tutorial from you, thank you. 👍
Thank you! Cheers!
Plz do a tutorial if we have multiple sensor, and we start them individually for data visualization.
Hi Muhammad, sure I'll be making some video lesson on how to interface multiple sensors to ESP8266 NodeMCU to send data to Blynk IoT Platform. It may take some time as creating quality content takes a lot of time and effort. I hope you understand. Good luck and best wishes!
Hey Great Video just wondering why there is a now a delay for the LED on/off function, wasn't happening on previous video.
Hi Subrata, If i understand your question correctly then Blynk server sometimes response late. As they have to handle lot of traffic on IoT server that cause delay. I hope this help. Have a good day!
superb and thanks
Most welcome Madhusha!
Have a beautiful day😊
Great tutorial, Just wants to know how to record this data
Hi Tarun, in Blynk IoT Cloud platform. You can store historical data in database but I guess it can only available in paid plan for Blynk. Check their website for more details. I hope this may find useful. Thanks
Please do a tutorial on how to monitor a reed switch, I can't figure it out myself.
Yes sure, I'll try to cover reed switch using Blynk App and dashboard
@@BINARYUPDATES thank you so much 😁
is there a way to use digital pins intead of the analog? I use dth11 temp sensor
Hi Oscar, I'd suggest use of virtual pin functionality supported by Blynk IoT Platform. But yes, you can sue digital as well. And this is because in the end, DHT11 is a digital temperature and humidity sensor. Good luck and best wishes!
is there any need of cloud or internet to the iot device for this type of connectivity
Yes using Cloud platform like Blynk, let you control devices from anywhere in the world. if you want just to control in local network then you can avoid using public cloud platform for your IoT Projects!
Can you do the same tutorial using esp32 please?
Yes will do in near future presently we're focusing on ESP8266 NodeMCU. Once this series over then we'll start ESP32. Thanks for your patience
How's the esp8266 connected with mobile application
Can u explain?
In this example project, we used Blynk IoT platform to establish communication between NodeMCU ESp8266 with Mobile App created with Blynk Platform itself. The Blynk platform takes care communication protocol and everything. And we have to insert WiFi creadentials into the arduino code which we upload in ESP8266 Microcontroller. Good luck and best wishes!
Bhai Android phone se programming kaise hogi new blynk 2.0 ki plz make video
Hi Sandeep, please understand Blynk is an IoT Platform which provide you mobile app and web dashboard to connect devices like NodeMCU, Arduino etc. You don't need to program Android Phone. You can build Android App using Blynk2.0 to use on your Android Phone. I hope this may help you. Good luck!
Sir is there any way i can contact you?
Yes, you'll find our email address on our website or feel free to leave your question here. I usually answer every comment. Good luck!
Bro can you send me the library of this code.
Hi the code is provided in the description. Its an GitHub link where you can download entire blynk project of NodeMCU ESP8266. Good luck and best wishes!
