Sur le SHT3x de la photo, ce condensateur est déjà sur le circuit imprimé (petit carré jaune) il n'est donc pas utile d'en rajouter. La résistance de 4,7k n'a rien à voir, elle sert de tirage au plus 5V pour le bus One Wire si la sortie du microcontrôleur est à collecteur ouvert.
Sensor de umidade digital e de ultrabaixa potência SHTC3 O sensor de umidade digital e de ultrabaixa potência SHTC3 da Sensirion foi construído com base no sucesso do sensor SHTC1 com uma faixa de tensão de alimentação mais ampla (1,62 a 3,6V) e maior precisão (±2% de umidade relativa, ±0,2°C), permitindo maior flexibilidade.
The SHT3x, SHTCx, and SGPx are available in the Arduino Shield form factor as well. The SHTCx digital humidity sensors are designed especially for high-volume consumer electronics applications. These sensors are designed to overcome conventional limits for size, power consumption, and price-performance ratio, in order to fulfill the current and ...
