esp32与DHT11的连接: DHT11和DHT22传感器有3针,有4针两种,用到的只有3个针,分别是+,数据传输针和地,分别对应esp32的vcc,pin和GND。连接如图所示。 连接好后,打开arduino ide,新建一个文件,选择自己的端口和esp32的类型,我这里是端口3和NodeMCU-32s。 /** ESP32 + DHT11 Example for eyeglasses https:/...

In this tutorial, we will learn to interface DHT11 and DHT22 sensors with ESP32 using Arduino IDE. We will create a DHT11/DHT22 web server with ESP32 to display temperature and relative humidity values on a Web page. In this project, we will create two types of DHT11 and DHT22 web ...

I have been able to interface with other things while the camera is enabled, specifically the DHT11 Temperature/Humidity sensor. That works fine. It's almost like when the camera is in use the ESP32Cam is not able to do PWM (maybe the camera module is using up all of the available sy...
