本文介绍了如何解决SHT1x温湿度传感器库文件在Arduino平台上编译失败的问题。具体报错为WProgram.h: No such file or directory和expected ',' or '...' before numeric constant。解决方法是将WProgram.h替换为Arduino.h，并检查代码中的常量定义。通过这些步骤，您可以快速解决问题，避免自行排查的时间成本。

我购买了一个SHT1x温湿度传感器，从DFRobot产品网页上（https://www.dfrobot.com.cn/index.php?route=product/product&filter_name=SHT1x&product_id=114）下载了库文件（http://www.dfrobot.com/image/data/DFR0066/SHT1x_Arduino.zip），解压后存放在Arduino安装目录下（D:\arduino-1.0.4\libraries），然后调用例程：D:\arduino-1.0.4\libraries\SHT1x\examples\ReadSHT1xValues，编译时失败，出现如下提示： In file included from ReadSHT1xValues.pde:11: D:\arduino-1.0.4\libraries\SHT1x/SHT1x.h:15:22: error: WProgram.h: No such file or directory In file included from ReadSHT1xValues.pde:16: D:\arduino-1.0.4\hardware\arduino\cores\arduino/Arduino.h:111: error: expected ',' or '...' before numeric constant D:\arduino-1.0.4\hardware\arduino\cores\arduino/Arduino.h:112: error: expected ',' or '...' before numeric constant 请问这是什么原因？如何解决？ 多谢！ |
与以太网盾连接后,已经可以正常实现网络访问获取温湿度
可是，我使用新的库文件和其附带的例程，虽然可以编译了，却得到如下运行结果：
Starting up
Temperature: -40.0099983215C / -40.0180015563F. Humidity: -4.44%
Temperature: -40.0099983215C / -40.0180015563F. Humidity: -4.44%
Temperature: -40.0099983215C / -40.0180015563F. Humidity: -4.44%
Temperature: -40.0099983215C / -40.0180015563F. Humidity: -4.44%
这样的结果明显和实际情况不符。
请帮忙看看有什么问题，多谢！
例程如下：[code]/**
* ReadSHT1xValues
*
* Read temperature and humidity values from an SHT1x-series (SHT10,
* SHT11, SHT15) sensor.

#include
// Specify data and clock connections and instantiate SHT1x object
#define dataPin 10
#define clockPin 11
SHT1x sht1x(dataPin, clockPin);
void setup()
{
Serial.begin(38400); // Open serial connection to report values to host
Serial.println("Starting up");
}
void loop()
{
float temp_c;
float temp_f;
float humidity;
// Read values from the sensor
temp_c = sht1x.readTemperatureC();
temp_f = sht1x.readTemperatureF();
humidity = sht1x.readHumidity();
// Print the values to the serial port
Serial.print("Temperature: ");
Serial.print(temp_c, DEC);
Serial.print("C / ");
Serial.print(temp_f, DEC);
Serial.print("F. Humidity: ");
Serial.print(humidity);
Serial.println("%");
delay(2000);
}[/code]电路连接按照产品库中的图例连接的。
