5. Recibe los datos del ESP en NodeRED con MQTT
La cosa ya se empieza a complicar...
TODO
- Explica MQTT
- Instalar plugin NodeRED dashboard
|
Tipo |
Descripción | Unidades | Topic MQTT |
| Sensor | Lectura sensor temperatura DHT11 | ºC | taller/tXX/sens/DHT11/temp |
| Sensor | Lectura sensor humedad relativa DHT11 | %rh | taller/tXX/sens/DHT11/hum |
| Sensor | Lectura sensor luminosidad LDR | Volts | taller/tXX/sens/LDR |
| Actuador LED | Indicador LED Verde | taller/tXX/leds/verde | |
| Actuador LED | Indicador LED Rojo | taller/tXX/leds/rojo |
NOTA: tXX será tu número de equipo. Es decir, en caso de que sea es el equipo número uno (equipo 1) deberás publicar los datos de temperatura en el topic taller/t01/sens/DHT11/temp

X. Ejercicio extra para los más valientes [OPCIONAL]
¿Te através a cambiar la luminosidad de los leds mediante el nodo Slider de la UI?
Esta vez sin pistas... y sin solución!
