Lecture-V ESP32 & the MQ 135 Air Quality Sensor

Didn't work with this schema

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

Very nice 👌

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

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

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 😢

Awesome Sir 👌
