I currently can't find the notification option in the template that I can use in this case?
So many thanks!!!!
Your welcome
well explain..thank you
Your welcome
@@sritu_hobby I got a doubt.. Can I make a circuit using nodemcu n send SMS using blynk???
and can add dht11(temperature sensor) and read the value in the lcd???
i am sorry to bother you but the new Blynk app doesn,t have the features that you show us.Can you help me to fix it
Hello, I did everything the same but blynk is saying device is offline. I tried it with a different code with just turning on and off the led and it worked it said the device was online so I am sure the auth code and credentials are correct. Is there anyway I can fix this?
We can use mq135
can i know the connection if i using esp32?
Is it safe to connect itu directly cuz it working voltage is 5v
Does the code use an algorithm?
I have problem.
When i turn of first time,and I set the button to on.Notification and buzzer working normally.
But when Nodemcu restart (Power outage),notification and buzzer not working.I must set the button to off and to on again for normally notification and buzzer.
Do you know how to fix it?
Automaticly normally notification and buzzer after restart
Which power supply you use for this and please tell me about its output rating is that 5v 500maph
You can use a 9v battery
New blynk app vr kru shakto ka apn please reply me sir
I can't find the new project section !!please can you sent me the servion you used
my nodemcu keep restarting when i put my mq2 sensor on the pin. i need to connect to my voltage regulator and also my usb on my laptop. if i remove the usb from my laptop (just using my voltage regulator my nodemcu restart. i did my voltage regulator by using 12v input and 5v output and i have another 2 sensor (digital signal) that works fine without mq 2 by using the same code..i dont know what is the problem.. i need your thought on this..do u have any idea??
I think this is sensor issue..please replace the mq2 sensor and try again
@@sritu_hobby i already did change the sensor.. but still same.. i dont think it is sensor issue because when i use 2 supply that is form my voltage regulator and from then usb cable at the same time.. its works very well.. the snesor can detect and then activate the relay.. and all my sensor also works well.. but it just happen when i unplug the usb cable (just using my voltage regulator.) the nodemcu keep on restarting..

Can I use MQ6 instead, sir?
yes of course

Is this gonna work without lcd ?
yah
pless TELL ME NAME OF THE SONG
Brother my arduino ide says Liqiuid crystal is may not be supported to your esp8266 could you plz help me
@@sritu_hobby bro i didn't have I2C module but I've 16x2 lcd display so i didn't no how to connect it to the bread board
Can you share me code for without lcd plz this is my 1st IOT experiment 😬😬
@@sritu_hobby bro could you plz make a video on it 😐😕
@@sritu_hobby what is the meaning of "connect it pin row"?

You can use old Blynk app.
@@sritu_hobby bro can we use same code for blynk iot which we used for blynk legacy?
as i have created gas level monitoring system by using blynk app as you showed in one of your video , now as blynk legacy is gone , i can't complete my project , please help what i should do?
do you have any other video on gas leakage detector using blynk iot
@@sritu_hobby if yes than please reply, my whole project is under way, i have completed all stages of this video, but now blynk legacy is no more and there is blynk iot instead and my mentor is saying it will not work now as code was for blynk app
