MicroPython IoT Weather Station Example for Wokwi.com

Now click on the DHT22 sensor in the simulation,
change the temperature/humidity, and you should see
LEDs change color like:
Izquierdo (Temperatura)
 AZUL  = temperature < 0
 VERDE = temperature >= 0 and temperature < 30
 ROJO  = cualquier otro valor de temperatura

Derecho (Humedad)
 AZUL  = humedad < 25
 VERDE = humedad >= 25 and humedad < 80
 ROJO  = cualquier otro valor de humedad
