使用ESP8266 内核为 Arduino 读取传感器数据 我们有几种方法来读取数据并处理 DHT11 使用的专有单线通信协议: 盲循环:等待固定的时间,并假设 I/O 将在该固定延迟过去之前完成。此方法不适合我们读取传感器数据,因为 0s 和 1s 时序不同,您可能会失去同步,但我们将使用它来启动信号到 DHT,因为这是使 DHT11 从...
您可以使用任何传感器来代替DHT11温度传感器。可以参考使用LM35和Arduino读取温度。RTC模块DS3231使用I2C通信...
一般从网上买的 Arduino 传感器套件版本的 DHT11,会有一个带 LED 的焊好的板,上面有三个接线引脚,分别是 VCC, GND, DATA,接线时,只要将 VCC 接到 Arduino 5V上,GND 接到 Arduino GND 上,DATA 引脚接 Arduino Pin8上即可。 Arduino_KY-015_Keyes_Temperature_humidity_sensor_module_connection_diagram.png ...
