we will set an asynchronous HTTP server. AsyncTCP is another library that we will be incorporating as a dependency for the ESPAsyncWebServer library. This library will not be used directly inside our program code and only acts as the base for the first library. ...

腾讯举办的AIoT应用创新大赛也开始有一个月时间了,大伙们都该入门的入门了,该折腾IDE的各种倒腾,这个用不习惯就换另一个。也有部分人平时工作,没啥时间瞎捣鼓的,比如我,我就直接用官方的IDE,不顺手,但是能用,省事是比较重要的。那么接下来我就记录一下,基于i.MX R
使用DHT sensor library库(需自己安装,安装教程在上面的ESP8266开发环境搭建教程中)来直接读取DHT11的数据。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #include <DHT.h> //调用DHT库 DHT dht(D1,DHT11); //设置Data引脚所接IO口和传感器类型 void setup(){ //初始化函数,只在程序开始时运行一次...
DHT传感器引脚:代码注释中提到了Feather HUZZAH ESP8266开发板的引脚使用,确保你使用的开发板和引脚连接正确。 NMEA句子格式:在sendTempData()函数中,生成的NMEA句子格式为$TD "Hum:<humidity>,Temp:<temperature>"*<checksum>。确保这种格式是TILE设备所期望的。
你好，我也开始学习DHT22，仿照DHT11的程序，仅仅是把DHT11的时序延迟时间更改了一下，可能显示精度不够...
So, will the 8266 recognize "#define DHTPIN D2" if it is coded per se OR do I need to add "#define ESP8266_RAW_PIN_ORDER" at the beginning of the sketch for this to work? Re: ESP8266 DHT22 "Failed to read from DHT sensor!" #71372 By icons - Sun Oct 29, 2017 7:12 pm...
