How to make a GAS-level monitoring system with ESP32 board

This video includes how to make a GAS level monitoring system with an ESP32 board. For that, I mainly used the MQ2 GAS detection sensor. With this system, we can monitor these values on our smartphones or computers from anywhere in the world.

Sir, can I get the reading on LCD when wifi is not available ?

[@kiel9303]

I tried doing this tutorial. I am using MQ135 and it works on detecting the gas. However, my buzzer doesn't make a sound when it sense a gas. I am using the same buzzer like on your tutorial but it didn't work. Pls help me fix it sir

[@gojosatoru7836]

Sir, what's the unit of your reading

[@tanvitikam3968]

Sir does gas gets trapped in the sensor ? As with 0 gas leak it still shows 19-20 fluctuating values on screen

pliss , I want a request to make an automatic door lock using nodemcu esp8266 with additional lc. You have previously made use of Arduino

[@carlosangellotti5710]

Hi Sir, I have a question, the sensor is powered at 5V and the analog pin of the ESP32 supports up to 3.3V, how do you resolve this issue? Is it an error in the circuit or a lack of concept on my part?

[@zharkynomarov9545]

Why doesn't my buzzer make a sound? if you connect to +, then there is sound, but if you connect simultaneously with mq-6, the buzzer will stop working

[@emmanuelbulacio1283]

Hi, great video
Just one doubt. The esp32 input pins support up to 3.3v. but the MQ2 run on 5v
How is it possible?

[@sritu_hobby]

Its ok

[@emmanuelbulacio1283]

@@sritu_hobby I mean, you say it's ok to put the 5v analog range in a 3.3v analog range?
I you put 5v in the analog input, even if it doesn't break, don't believe it's gonna be a faithful data

[@jaikrish50]

Sir please help me I need same project but instead of gas detector I'm going to use DHT11 sensor and instead of buzzer I will use 2 channel relay. So whenever the temperature reaches above 35° one of the relay to be on state . Please help me sir
