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...
that it can detect even the slightest changes in the environment, making it ideal for applications such as HVAC systems, dehumidifiers, and weather stations. **Ease of Integration and Use** The sensor's single-wire serial interface makes it incredibly easy to integrate into any Arduino or elect...
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。
printf("Sorry! Sensor dosent ans!\n"); databuf=0; } } return 0; } 4编译运行该代码,获得温湿度数据: 从结果可得: 温度为26.0摄氏度 湿度为44.0% 5。接下来是LCD显示数据: LCD显示模块led_dht11.pyd 参考了git上的Adafruit_CharLCD()代码,主要的功能是读取dht11的执行结果进行lcd显示 ...
Interface #include"dhtnew.h" Constructor DHTNEW(uint8_t pin)defines the dataPin of the sensor. void reset()might help to reset a sensor behaving badly. It resets the library internal settings to default, however it does not reset the sensor in a hardware way. ...

Each DHT11 sensor is calibrated in an extremely accurate humidity calibration chamber. The calibration coefficients are stored in the OTP memory as a program, and these calibration coefficients are called internally during the processing of the detection signal. The single-wire serial interface makes ...
