非常感謝，很需要這代碼

這個(gè)可以換成其他的I2C引腳嗎

A4.A5是IIC專用SCL和SDA

后悔沒有存代碼，現(xiàn)在我也在找這類材料

這個(gè)可以換成其他的I2C引腳嗎

這個(gè)傳感器就是個(gè)貴呀！

請(qǐng)參考/***************************************************
  This is an example for the SHT31-D Humidity & Temp Sensor

  Designed specifically to work with the SHT31-D sensor from Adafruit

  These sensors use I2C to communicate, 2 pins are required to  
  interface
  Hardware connections for Arduino Nano:
  VDD to 3.3V DC
  SDA to A4
  SCL to A5
  GND to common groud
****************************************************/

#include <Arduino.h>
#include <Wire.h>
#include "Adafruit_SHT31.h"
#include "LiquidCrystal_I2C.h"

Adafruit_SHT31 sht31 = Adafruit_SHT31();

#if defined(ARDUINO_ARCH_SAMD)
// for Zero, output on USB Serial console, remove line below if using programming port to program the Zero!
   #define Serial SerialUSB
#endif

void setup() {
//#ifndef ESP8266
// while (!Serial);     // will pause Zero, Leonardo, etc until serial console opens
//#endif
  Serial.begin(9600);
  Serial.println("SHT31 test");
  if (! sht31.begin(0x44)) {   // Set to 0x45 for alternate i2c addr
    Serial.println("Couldn't find SHT31");
    while (1)
    delay(1);
  }
}


void loop() {
  float t = sht31.readTemperature();
  float h = sht31.readHumidity();

  if (! isnan(t)) {  // check if 'is not a number'
    Serial.print("Temp *C = "); Serial.println(t);
  } else {
    Serial.println("Failed to read temperature");
  }
  
  if (! isnan(h)) {  // check if 'is not a number'
    Serial.print("Hum. % = "); Serial.println(h);
  } else {
    Serial.println("Failed to read humidity");
  }
  Serial.println();
  delay(5000);
}

各位網(wǎng)友，我在某寶購(gòu)買了sht30和sht31后，頁(yè)面會(huì)附上adafruit sht3xd材料的網(wǎng)址，其中的文件包就包含<adafruit sht3xd.h>,再在度娘上搜I2C_Lcd1602頭文件很方便，借鑒arduino+dht11的文章以及aruduino+I2C_Lcd1602 test等文章，修改一下就行。祝你們成功！有問題歡迎交流
