AHT10与Arduino UNO连接

基于Arduino UNO的AHT10代码

#include < Wire.h> // Library to establish I2C communication
#include < AHT10.h> // Library to use the AHT10 sensor

AHT10 myAHT10(0x38); //AHT10 instance, address 0x38

void setup ()
{
     Wire.begin(); //Function that initializes the Wire library.
     Serial.begin(9600); //initializes Serial communication.
     Serial.println("Initialising AHT10 Sensor");
     if(!myAHT10.begin()) //If communication with the sensor fails, an error message is printed
     {
       Serial.println ("Sensor error!");
       while(1);
     }
}

void loop()
{
  float temp = myAHT10.readTemperature(); //read temperature from sensor and store it in a variable.
  float hum = myAHT10.readHumidity(); //read humidity from sensor and store it in a variable.
  
  Serial.print("Temp: "); Serial.print(temp); Serial.print("°C  "); //print the temperature value.
  Serial.print("Humidity: "); Serial.print(hum); Serial.println(" %"); //print the humidity value.
  delay(1000);
