mine only achieved until 28-29ppm. is it possible to increase the number of ppm? because idk how. already tried with other brand of MQ7 sensor. yet the result still the same. if possible, can you tell me how?
Sir Great Video 😭 Can you just please the make same video just this time displaying sensor data on 0.96 OLED display 🙏🏻 Can you provide source code for this ESP 8266- MQ135 - 0.96 Oled
the sensor you are using requires 15 volt DC input !!! And I think the board you are using can only supply 5 volt DC !! How can we use this sensor with a 5 Volt board ?
Excelente video, muchas gracias, saludos desde Colombia.
Thank you team.
Educational and useful video. very nice. I really like.
Good project, add an alarm to detect gas leak like buzzer.
Make next time on the similar video.
Did u preheat the sensor before connecting? Also how did you calibrate it.
Using Perfume as Gas is Awesome.
Nice tutorial

Hello, How to Electronics, do you know how to connect the MQ131 sensor to the ESP32, or do you have a video demonstrating it?
Sir, whether we can connect gas level monitoring over internet using ESP8266 with gas leakage detector using gsm module and Arduino with sms alert
why cant i see the graph in thinkspeak?
Please tell how can u include the lcd in this same thing
how to preheat the sensor? can u explain ASAP.
Why i have no graphic from thingspeak private view
In intro How To Lectronics nice.
can't you see the big letter E on left side??
Sir can we use same code for MQ7 gas sensor??
Why in serial monitor it said
Conneting to.....
(My wifi name)
It repeat more and more. Can i know why?
Can we use Mq2 instead of Mq5 ?
MQ6 sensor work ?
How to simulte the esp32?
Good sir, can add more than 2 sensors and a buzzer
why (client.stop();) not declare ?
is this output is PPM or ?
pls help
'WiFiClient' does not name a type
Sir I did step by step how u teached like that only I did finally i got output
how can we do this for petrol?
graph is blank in the thingspeak..
Bro how can we Install esp8266libraries??
In my case, entry is recored in thinspeak but data is not uploading. What should I do?
same here do you get solution?
You need to apply a delay of 20s
I need to connect mq9 and mq135 sensors to nodemcu pls suggest any analog extender
Use Analog multiplexer IC 74HC4067 or 74HC4051.
please help me. I didn't get any values
Good job
Man what we have to take the value if h
Can u suggest me...from where u get the program of this project...
Visit the link in description from PC.
why you connect it to Vin pin? why u didn't use pin 3.3V ?
Bcoz gas sensor requires 5V.
@@HowtoElectronics ah ok :)
@@HowtoElectronics why i cant use Vin pin in my node mcu? so i decide to use VU pin
Sir Great Video 😭
Can you just please the make same video just this time displaying sensor data on 0.96 OLED display 🙏🏻
Can you provide source code for this
ESP 8266- MQ135 - 0.96 Oled
Sir. Why the thinspeak had the entries, but it's dont plot the graph????.
sama bro :OO
@@amirsaahal2425 gua dah dapat solution bro. Tapi coding lain skit laaa .
@@badrulaminbinmdnayanb2330 bro boleh share coding tak ? apa ig bro? nt sy dm no
@@amirsaahal2425 nayanbadrul
@@badrulaminbinmdnayanb2330 bro bisa bantu saya ?
Is it possible to do this without using Arduino Uno board?
You can use any microcontroller
@@HowtoElectronics U didn't use any microcontroller right?.and one more.. is Node mcu esp 8266 is same as esp 8266 12E
MQxxx sensors must be calibrated. Otherwise, meaningless numbers are read.
the sensor you are using requires 15 volt DC input !!! And I think the board you are using can only supply 5 volt DC !! How can we use this sensor with a 5 Volt board ?
The sensor works at 5v not at 15v.
Hiii...what is the unit for gas level here?
It is in ppm
@@Alpha-eh3ol thank you
Can u explain the code sir
