Lecture-V ESP32 & the MQ 135 Air Quality Sensor

The MQ-135 needs to be stabilize for the correct readings. Leave it in open air for 5-6 hours. To understand the units of PPM and AQI index check out the video here:
• Air Quality Index (AQI)

Awesome Sir 👌

[@prakharsodhiya8408]

Very nice 👌

[@denise4ever242]

Can we add dht11 sensor to this circuit? If yes what pins of esp32 should we use and what is code?
I'm a complete beginner and would definitely appreciate any help 😢

[@RandomGuy-df1oy]

Do I have to use breadboard and jumper wires for connecting esp32 to sensors?

[@denise4ever242]

Please reply sir. Why do I get readings at 560 and its unstable decreasing and increasing

[@yilberrojas8306]

Why don't you use a 5 volt power supply? Why are you using a voltage divider? Does that pin supply 5 volts?
