DHT33 sensor

Berichtdoor jack » 18 feb 2015, 21:57

De tijd staat niet stil. Ik heb inmiddels de DHT33 sensor (equivalent met de RHT04) aangeschaft.
Deze DHT33 sensor is nauwkeuriger dan de DHT22. In deze DHT33 sensor zit de Dallas DS18B20 geïntegreerd. Alleen krijg ik deze DHT33 met de Nodo nog niet aan de praat.
Ik heb zowel de plugin_006 als de plugin_005 uitgeprobeerd. Maar helaas, geen meetwaarden van de DHT33 te zien. Ook het toevoegen van een 4,7kOhm weerstand tussen de Vcc en de Data geeft geen resultaat.

Datasheet DHT33:

Zou mooi zijn als we de bestaande plugin hierop kunnen aanpassen. Maar ik weet dat de auteur van die plugin zijn handen vol heeft op dit moment. Bovendien is het lastig testen als je geen hardware hiervoor hebt... even geduld!

Misschien voor andere handige mensen, die het 'even' kunnen aanpassen als daar behoefte aan is....

Op arduino.cc las ik dat Rob Tillaart zowel voor de DHT33 als de DHT44 testcode beschikbaar heeft
al is die laatste wel in een andere (hele nette) behuizing Afbeelding





Voor de programmeurs:

Hans,

Ik heb Paul een DHT33 beschikbaar gesteld om te testen.

Heren,

De DHT-33 is volledig compatibel met de DHT-22. Nu heb ik van Jack een DHT-33 toegezonden gekregen en een proefopstelling gemaakt en guess what: werkt gewoon.

Ik heb een kleine aanpassing aan de plugin gemaakt zodat je ook de 33 kunt opgeven, maar je kunt in je config bij de _CORE kun je 22 gebruiken.

Als de DHT-44 net zo makkelijk gaat.... :lol:
Groeten Paul
