Kilka dht22 na jednym module

[soren]

Cześć mam pytanko czy ktoś stworzył juz soft z kilkoma najlepiej z 5-6szt dht22 na jednym module najlepiej wemos?

Na Arduino ide na nowej rozwijanej wersji biblioteki jest przykład z dwoma dht. Dodanie kolejnych, to jedna dodatkowa linia kodu na czujnik.
Biblioteką jest tu https://github.com/klew/arduino

Dziękuję

Mała poprawka: tam był kiedyś przykład z dwoma DHT . Teraz widzę, że jest jeden.
Ale zmiana nadal jest prosta. Pod tymi liniami kodu:

Kod: Zaznacz cały

  // CHANNEL6 - DHT22 Sensor
  new Supla::Sensor::DHT(DHTPIN, DHTTYPE);

dodaj:

Kod: Zaznacz cały

  new Supla::Sensor::DHT(dht2pin, dht2type);
  new Supla::Sensor::DHT(dht3pin, dht3type);

pin i typ ustaw zgodnie z fizycznym podłączeniem.

To sie wgra tylko na arduino mega czy na wemosa też da radę?

Nie twierdzę, że DHT22 to złe czujniki, ale zapoznaj się z tym:

oraz:

Osobiście wolę BME280.

przykład wemos 3 X DHT22

Kod: Zaznacz cały
