To add five DHT22 sensors you’ll need, for each sensor:
  • A DHT22 part (3 pins: VCC, DATA, GND)
  • A 4.7 kΩ pull-up resistor on the DATA line
  • Wire VCC to +3V3, GND to GND, DATA to a unique ESP32 GPIO
Which five ESP32 GPIO pins would you like to use for the DHT22 DATA lines? (e.g. IO4, IO16, IO17, IO21, IO22)
Assign GPIO pins
Specify pin assignment

I'm choosing IO4, IO16, IO17, IO21, and IO22 for the sensor data pins. What's next for setting up the pull-ups?
