Fonctionne très bien et à un prix avantageux

J'ai utilisé certains de ces capteurs DHT22 pour ajouter des affichages de température et d'humidité à mes caméras Web Raspberry Pi. Rien de plus simple, juste trois fils et la bibliothèque DHT22 Python d'Adafruit. La plupart des fournisseurs facturent 8 $ à 10 $ pour le capteur nu, mais ceux-ci sont fournis sur un PCB avec des trous de montage et un connecteur câblé. Le PCB a une résistance de rappel I2C et un capuchon de découplage, ce qui en fait une solution très propre.

Very accurate and has single decimal point accuracy

I ordered 2 of these and now find that I need more to complete my projects. The ones I have now, have been working for quite a while without any issue. The accuracy is excellent. Also, the library for Arduino are not huge and don't take up too much memory. I'm ordering more now.
