Learn how to display temperature and humidity readings on a web server using the ESP32 or ESP8266 boards: ESP32 DHT11/DHT22 Web Server using Arduino IDE ESP8266 DHT11/DHT22 Web Server using Arduino IDE DHT11 and DHT22 Temperature and Humidity Sensors The DHT11 and DHT22 sensors are used...
In this tutorial we’re going to show you how to build a web server with the ESP32 that controls the shaft’s position of a servo motor using a slider. First, we’ll take a quick look on how to control a servo with the ESP32, and then we’ll build the web server. ...
ESP32 发送板连接到 DHT22 温湿度传感器。数据引脚连接到通用IO 4(D4端口).您可以选择任何其他合适的 GPIO(阅读 ESP32 引脚分配指南)。按照下图对电路进行接线。 5. ESP32 接收器 (ESP-NOW + Web Server) ESP32 接收板接收来自发送板的数据包,并托管一个 Web 服务器以显示最新接收到的读数。 将以下代码上...
有两个步进电机驱动器,可控制两个双极步进电机。I2C总线也已断开,可用于APDS9960或LCD等组件。为了读取温度,需要断开连接到DHT22传感器的引脚以及用于读取环境光水平的光敏电阻。板上有一个模拟灯带,该模拟灯带具有三个MOSFET。步骤2:PCB我首先通过在Eagle中创建原理图开始了PCB设...
然后,将 Web 服务器设置为端口 80。 // Set web server port number to 80 WiFiServer server(80); 以下行创建一个变量来存储 HTTP 请求的标头: String header; setup() 在函数 setup() 里面,我们以 115200 的波特率开始串行通信以进行调试。 Serial.begin(115200); 您检查 BME280 传感器是否已成功初始化。
