我的主要 arduino 文件中有此代码：
#include <HIH4030.h>
HIH4030 humiditySensor(0);
float humidity;
void setup() {
Serial.begin(9600);
}
void loop() {
delay(1000);
humidity = humiditySensor.sensorRH();
}
这是我的 HIH4030.h 文件内容：
#ifndef HIH4030_h
#define HIH4030_h
#include "Arduino.h"
class HIH4030{
public:
HIH4030(int pin);
float ratioHumidity();
float sensorRH();
float trueSensorRH(float temperature);
private:
int _pin;
float sample;
float temperature;
};
#endif
//data sheet https://www.sparkfun.com/datasheets/Sensors/Weather/SEN-09569-HIH-4030-datasheet.pdf
这是我的 HIH4030.cpp 文件内容：
#include <HIH4030.h>
HIH4030::HIH4030(int pin)
{
_pin = pin;
}
/*
gives humidity as a ratio of VDD
*/
float HIH4030::ratioHumidity(){
//poll analogue in
return analogRead(_pin);
}
/*
gives humidity as a percentage - numbers taken from datasheet
*/
float HIH4030::sensorRH(){
//poll analogue in
sample = analogRead(_pin)*5; //multiply by 5 as sample is a decimal of Vdd
return (sample-0.958)/0.0307;
}
/*
gives humidity adjusted for temperature (in degrees C) - numbers taken from datasheet
*/
float HIH4030::trueSensorRH(float temperature){
float rh = sensorRH();
temperature = temperature*0.00216;
return rh/(1.0546 - temperature);
}
当我编译我得到这个错误：

[Stino - Error while compiling.]
我是 arduino 的新手，我正在使用 Stino Sublime Text 2 插件。我已经将我为不同平台编写的更复杂的温度传感器库转换为 Arduino，它运行良好——我看不出这个库和其他库之间有什么区别，但我一定遗漏了一些东西。
据我所知，我已经完全按照如何制作自定义类 Arduino 教程进行操作......
