Greetings. I have a problem with the configuration of the mq135. it gives me PPM readings too high in an environment with good air quality. it has a 1k resistor to regulate the voltage going into pin 34.
@@uploadideaswithitamar if we connect both dht11 and MQ135 sensors simultaneously will the display show both levels from the sensor is it possible. and just give me a basic idea on how to write the code . please reply immediately day after tomorrow is my project review
Very good my friend i love this stufs don't stop brother.
Thanks, will do!
Can three mq135 sensors be used for esp32?
Yes
Brother can we do this project with the help of ESP8266 ??
Yes
Does the program differ ??
class LiquidCrystal_I2C' has no member named 'init'
i have this error,please help
Write begin
@@uploadideaswithitamar thank you sir, i made a project just like you,fully same to same and it is working properly, thank you sooo much sir💝💝💝💝

Why did you connect this 1K ?
Can we put a dht11 sensor to this circuit?
Yes

Hello bro, can i change MQ135 to MQ-2?
Yes, you can
@@uploadideaswithitamarit's still the same, nothing will change in coding?
why you choose the threshold 300
You can choose another one it’s the best for me
Why blnkt not working plesse give me code or template
Did you get the code in the description?
how can i get the circuit diagram
😆
I can't?
it doesn't work,the data can not display in blynk and i2c board, it always show 0
Sorry, man!
@@uploadideaswithitamar Is your phone's wifi the same as esp32's?
I tried this but it's not working 😢
What are you doing wrong ?
