幸运的是,将DHT11或DHT22传感器连接到Arduino很简单。它们使用2.54mm间距的排针,因此您可以轻松地将它们插入任何面包板。用5V为传感器供电并将GND连接到地线。最后,将Data引脚连接到数字引脚#2。我们还需要在VCC和Data线之间放置一个10KΩ的上拉电阻,以保持它为高电平,以便传感器和MCU之间的正确通信。如果您碰巧有传感器的分线板,则无需添加任何外部上拉电阻...

OK,删除掉zip原文件后打开Arduino IDH,粘贴以下代码,来让DHT11温湿度传感器开工: #define dht_dpin A0 byte bGlobalErr; byte dht_dat[5]; void setup(){ InitDHT(); Serial.begin(9600); delay(300); Serial.println("Humidity and temperaturenn"); ...

Grove - DHT11 Temperature & Humidity Sensor is a high quality, low-cost digital temperature, and humidity sensor based on the DHT11 module. DHT11 is the most common temperature and humidity module for Arduino and Raspberry Pi. It is widely favored by ha
const int DHT_PIN = 15; //定义一个整形变量,目的是使用GPIO-15来接收来自传感器的数据 DHTesp dhtSensor; //定义一个DHT传感器 //arduino里的setup函数,执行一次 void setup() { Serial.begin(115200); //串口的速率 dhtSensor.setup(DHT_PIN, DHTesp::DHT11);//把DHT11与gpio第15号数字引脚关联。
The Arduino microcontroller, being the processing unit of the system, gets the sensor's measured value and compares it with the set threshold. The results are: when the measured room temperature is less than the minimum of the threshold value; then, the microcontroller turns on the heater. If...
