打开~/Documents/Arduino/libraries目录,可以看到我们已经把DHT的库下载下来了: 2.2 移植到新路径 前面咱们不是改了库的路径嘛,那么我们在编译的时候肯定会显示找不到头文件: $ arduino-cli compile --fqbn esp32:esp32:nodemcu-32s DHT11_demo /Users/reus/workspace/my_work/virtual-sensor/libs/arduino/exampl...

Arduino IF Statement Code Examplesby Lewis LoflinVideo for this page: Arduino Comparison IF OperatorsThink of a micro-controller as a box full of basic logic circuits, gates, etc. To control the "box" we have to tell it what hardware to use. We must tell the "box" how to manipulate ...
DHTNEW has some new features compared to the DHTlib code. The constructor has a pin number, so the one sensor - one object paradigm is chosen. So you can now make a DHTNEW object bathroom(4), kitchen(3), etc. Theread()function now reads both DHT11 and DHT22 sensors and selects ...
Here, I've included the files given by the ESP32-Examples.#include "DHT.h" #define DHT11PIN 16 #define LIGHT_SENSOR_PIN 36 #include <Adafruit_MPU6050.h> #include <Adafruit_Sensor.h> #include <Wire.h> #include <Wire.h> #include <Adafruit_GFX.h> #include ...
This Arduino project idea is rather practical because it features indoor and outdoor temperature and humidity measurement. It is based on theDHT11/ DHT22 sensor, theNRF24L01 transceiver modulefor the wireless communication and theDS3231 RTC. For the display we can either use16×2 character LCD...
然后,定义您正在使用的 DHT 传感器类型。如果您使用的是 DHT11,则无需更改代码上的任何内容。如果您使用的是其他传感器,只需取消注释您正在使用的传感器并注释其他传感器即可。 #define DHTTYPE DHT11 // DHT 11 //#define DHTTYPE DHT22 // DHT 22 (AM2302) //#define DHTTYPE DHT21 // DHT 21 (AM230...

If you want to redirect to another page, you just have to modify the User Code with the number of the page. Our second page will display data from the DHT11 temperature and humidity sensor. We have several labels to hold the temperature in Celsius, the temperature in Fahrenheit, and the...
