这篇博客介绍了如何使用Arduino与DHT11和DHT12传感器进行温湿度测量。 DHT11和DHT22传感器虽然规格不同，但工作原理相似，能提供数字信号。 内容包括硬件准备（Arduino UNO、面包板、传感器等）、软件准备（使用Arduino IDE和DHT库）以及代码实现。 DHT11和DHT22传感器用于测量温度和相对湿度。 这些在制造商和电子爱好者中非常受欢迎。 DHT11和DHT12传感器包含一个芯片，该芯片进行模数转换，并随温度和湿度发出数字信号。 这使得它们非常易于与任 …

Arduino library for I2C DHT12 temperature and humidity sensor. The DHT12 is an I2C temperature and humidity sensor. The constructor is called only with a TwoWire object (Wire, Wire1 etc) as the device has a fixed address. The user should call Wire.begin () in setup before calling the begin () function.

The DHt12 is an upgraded version of the DHT11 humidity temperature sensor, it is fully downward compatible, more precise and most importantly it adds an I2C interface. Features: compact size

DHT10/DHT11/DHT12/DHT21/DHT22 for Esp32 using RMT - Digital-Output Relative Humidity & Temperature Sensor Module. IMPORTANT This implementation will only work on with ESP32. Don't use this implementation for those MCU. This implementation requires 2 pins. One is used to write to the sensor and the other is used to read the data using RMT.
