# Wiring instructions:
# Connect DHT22 data pin to ESP32 GPIO 21 (or any other GPIO pin you prefer)
# Connect anode (longer leg) of LED to ESP32 GPIO 25 (or any other GPIO pin you prefer)
# Connect cathode (shorter leg) of LED to a current-limiting resistor (e.g., 220Ω)
# Connect the other end of the resistor to ESP32 GND (ground)
