Detailed & helpful video

[@SMEDehradun]

🙏

[@lukemarkg.carino5861]

Nice, very good video

[@SMEDehradun]

Thanks Luke

[@SMEDehradun]

Hello guys,
Code updated for NodeMCU.
You can download it from my guthub repository. Link is available in the video description.

[@user-ds4hu5xm6l]

many thanks, very useful , i need to receive notification when gases reached to threshold how can i make that

[@SMEDehradun]

Hi,
You can create custom notifications to receive the alert in app as well as in gmail.
This video can help you.

[@MegamindCreation]

Is it important to open the app in phone while using this project? Or we can just see the result in web?

[@SMEDehradun]

You can see the live results in web and Mobile app independently.

@@SMEDehradun okay thanks buddy😁

[@a_rahul_krishnan_2003]

Sir what is the ppm range for smoke (from incence stick) and LPG gas(lighter)if detected sir?

[@SMEDehradun]

Hi,
You can get it in the data sheet of the sensor.

[@pritish1337]

Hello, is it safe to connect the sensor to 5v because in some other video i saw connecting the mq135 to 5v can damage the board

[@SMEDehradun]

It’s depend on the property of the sensor, few sensor works on 5V & few on 3.3V. But All sensor of MQ series works on 5V.

[@pritish1337]

Esp32 or Esp8266 which one is better for use

[@SMEDehradun]

Both are good, depend on application.

[@pritish1337]

Last question can we connect multiple mq sensors to an esp32.

[@SMEDehradun]

Yes. You can connect.

[@user-kg8du8kq2g]

sir my esp8266 board is unable to connect to the cloud. it is just showing connecting to cloud in the serial monitor.

[@SMEDehradun]

Hi,
You need to check your blynk credentials & Wifi name & password.

[@user-kg8du8kq2g]

@@SMEDehradun all these things are correct but i am still not able to connect

[@SMEDehradun]

There is some issue with your credentials or wifi name or password.
You can do one more thins. Delete your old template and create new as per shown in the video.
& please follow each & every steps.
And even after it, not working, then let me know.

[@user-kg8du8kq2g]

@@SMEDehradun sir i have already tried it but it is not working

[@SMEDehradun]

K. Mail me your query at [e-mail]
I will look on it.
