DHT22数字温湿度传感器精度较高,可以替代昂贵的进口SHT10温湿度传感器。在对环境温度与湿度测量要求较高的情况下使用,该产品具有极高的可靠性和出色的稳定性。 与Arduino专用传感器扩展板结合使用,可以非常容易地实现与温度和与湿度感知相关的互动效果。 注意:DHT22的传感器接线是模拟--数字转换线。 产品参数 供电电压...
首先，我们需要包含DHT库，该库可从Arduino的官方网站上找到，然后定义传感器所连接的引脚，并创建一个DHT...

Arduino library for DHT11 and DHT22 with automatic sensor type recognition.DescriptionDHTNEW is stable for both ARM and AVR. It is based upon the well tested DHTlib code.HistoryDHTNEW has some new features compared to the DHTlib code.
I also recommend cross-checking the DHT22 with an Arduino separately. You can follow this code here for the testing purposes: https://www.theengineeringprojects.com/ ... dht22.html 35p32fan Posts:12 Joined:Wed Oct 11, 2023 1:12 pm ...
