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:/...
Inside the DHT_reader_task() function, first the GPIO pin connected with the data pin is set using setDHTgpio() function. This function takes in a single parameter which is the ESP32 GPIO pin number that will output the sensor data. Then inside an infinite while loop, we will start rea...
In this ESP32 tutorial, we will check how to get temperature measurements on the Arduino core running on the ESP32, using a DHT22 temperature and humidity sensor.
Note: ESP32/ESP8266 boards will be used in station mode to connect these boards to your local WiFi network. But you can also create a soft access point web server with ESP32/ESP8266. DHT11/DHT22 Introduction The DHT11/DHT22 is a sensor which measures relative humidity and temperature sen...
