Blynk ioT | Temperature and Humidity Monitoring using DHT11 Sensor and Blynk IoT

In this video, I'll be showing you how to monitor DHT11 sensor data through the Blynk IoT platform. The DHT11 sensor is a low-cost, temperature and humidity sensor that can be used in a wide range of applications. With the Blynk IoT platform, we can easily collect, monitor and visualize the data from the DHT11 sensor in real-time.
In this tutorial, we will be using an eap8266 NodeMcu board and the Blynk app to build a simple IoT project. We'll walk you through the step-by-step process of connecting the DHT11 sensor to the esp8266 nodemcu board, configuring the Blynk app, and setting up the Blynk server to receive and display the sensor data.
We'll also show you how to customize the Blynk app to create a user-friendly interface to monitor the sensor data in real-time. You'll be able to see the temperature and humidity readings on your smartphone or tablet, and get alerts when the readings go outside a set threshold.
This video is perfect for anyone who wants to get started with IoT and learn how to use the Blynk platform to collect and monitor sensor data. No prior experience with IoT or programming is required, as we'll guide you through the entire process.
So, grab your Esp8266 board, DHT11 sensor, and your smartphone or tablet, and let's get started!

hi bro,can we monitor the data value on phone from a far distance?

[@PotatoNachoIT]

as long as ur wifi connects

[@tfkioT]

Anywhere from the world

[@ahmadirfannurudin5679]

Your video is good brother, thankyou.. but can you give me library DHT.h brother?

[@tfkioT]

Search "dht" on library manager & install dht by adafruit

[@faridayeasmin1864]

Good

[@tfkioT]

Thanks ❤️

Bhai please
Google control 4 light par video banaiye
Jise kahi se bhi control kar le

[@tfkioT]

With blynk ?

[@PriyankaKumari-mk5pm]

@@tfkioT yes

[@PriyankaKumari-mk5pm]

Any place control it

[@tfkioT]

Okay I will make a video soon

Your humidity data might be confidential to girls, make sure to blur it next time.
