I keep disconnected on Blynk

Need Help With My Project
1

i am new to blynk application i tried using multiple dht22 sensor and it keeps disconnecting but if i use only 1 sensor its usable can some one help me

sorry for my english

You have a number of issues.
First of all, your choice of GPIO pins for your sensors (GPIO 0-5) is not great…

The ESP8266 doesn’t really have 6 pins that are suitable for this. You should read this:

and don’t forget that the “D” numbers screen-printed onto a NodeMCU or Wemos D1 Mini are not GPIO numbers.

You are also doing the equivalent of 15 Blynk.virtualWrite operations one after another (the Blynk.Notify and LED.on/off commands are effectively the same as Blynk.virtualWrites). This is going to cause you problems…

Also, please don’t use Blynk notifications in this way, write the data to a value widget or similar, and save the notifications for unusual events.
