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。 #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 Serial.begin(115200); //设置串口波特率 dht.begin...
使用DHT sensor library库来直接读取DHT22的数据。 代码语言:javascript 复制 #include <DHT.h> //调用DHT库 DHT dht(D1,DHT22); //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 Serial.begin(115200); //设置串口波特率 dht.begin(); } //https://blog.zerun...
This is an Arduino library for the calibrated AM2302/AM2303 digital temperature and relative humidity sensor on a DHT22 breakout PCB.Library featuresRead 16-bit temperature (synchronous blocking) Read 16-bit relative humidity (synchronous blocking) Configurable number of read retries when a read ...
(0.3.2) Added setSuppressError() and getSuppressError() so the library will not output -999 but the last known valid value for temperature and humidity. This flag is useful to suppress 'negative spikes' in graphs or logs. Default the error values are not suppressed to be backwards compatib...
DHT-sensor-library, 用于DHT11DHT22的Arduino库,等温度湿度传感器 这是一个用于DHT系列低成本温度/湿度传感器的Arduino库。教程:https://learn.adafruit.com/dht下载。点击右上角的下载按钮,将未压缩的文件夹重命名为 DHT 。 检查DHT文件夹是否包含 DHT.cp
The easiest way to install the library is via the Arduino IDE library manager. To open it, go to Sketch -> Include library -> Manage libraries and the library manager should appear. There, type “DHT22” on the search bar and install the one named “DHT sensor library for ESPx“, as...
Arduino library for DHT sensors which can be easily used to get values of temperature and humidity only by calling two lines of functions. We will see later on how to do it. Now let’s see how to install the DHT library in Arduino. This library is provided by Adafruit. Follow these ...
Refer toHow to install libraryfor Arduino. Restart the Arduino IDE. Open “ DHTtester” example via the path:File → Examples → Grove_Humidity_Temperature_Sensor-master → DHTtester. Through this demo, we can read the temperature and relative humidity information of the environment. ...
Since we are now using two pins, we will also need to make changes in the libraries used. As an example, I modified the DHT-11 library from Adafruit. 1#ifndef DHT_H2#defineDHT_H3#ifARDUINO >= 1004#include"Arduino.h"5#else6#include"WProgram.h"7#endif89/*DHT library1011MIT license12...
