Lecture-V ESP32 & the MQ 135 Air Quality Sensor

[@RandomGuy-df1oy]

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

[@yilberrojas8306]

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

[@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 😢
