For each reading it sends 2 bytes: the integer value and the fractional value. So any NAN must be the result of your code. When developing code to read from devices, the first step is to print the raw data it is sending, and then you can see if that makes sense, according to the data sheet. – Weather Vane. csdn已为您找到关于dht.h库文件相关内容,包含dht.h库文件相关文档代码介绍、相关教程视频课程,以及相关dht.h库文件问答内容。为您解决当下相关问题,如果想了解更详细dht.h库文件内容,请点击详情链接进行了解,或者注册账号与客服人员联系给您提供相关内容的帮助,以下是为您准备的相关内容。. In practice, this instance usually has a data structure in common with other instances, but the values stored in the instances are separate. Changing the values in one instance will then not interfere with the values of some other instance. A compute instance can be software or hardware which can run code, for example a CPU, GPU or a virtual. Both are also fairly sluggish, in that you can't query them more than once every second or two, so sensor readings can be up to 2 seconds old (1 second with the DHT22) 智能手机一部 + app(Blynk) 4 napa paint gun kit, Tandy Leather, Inc Device E was selected as the best of the six I originally started with DHT11, DHT22 and AM2302.
