有沒有哪位大神幫我看看我這個代碼哪里有問題 dht11函數庫也導入了 代碼在下面：
#include<dht11.h>
dht11 DHT11;
#define DHT11PIN 2
double dewPiont(double celsius, double humidity)
{
double A0 = 373.15 / (273.15 + celsius);
double SUM = -7.90298 * (A0 - 1);
SUM += 5.02808 * log10(A0);
SUM += -1.3816e-7 * (pow(10, (11.344 * (1 - 1 / A0))) - 1);
SUM += 8.1328e-3 * (pow(10, (-3.49149 * (A0 - 1))) - 1);
SUM += log10(1013.246);
double VP = pow(10, SUM - 3) * humidity;
double T = log(VP / 0.61078);
return (241.88 * T) / (17.558 - T);
}
double dewPointFast(double celsius, double humidity)
{
double a = 17.271;
double b = 237.7;
double temp = (a * celsius) / (b + celsius) + log(humidity / 100);
double Td = (b * temp) / (a - temp);
return Td;
}
void loop()
{
if (DHT11.temperature >= 40 || hc == 'w')
{
for (int i = 0; i < 5; i++)
{
digitalWrite(SC, HIGH);
Serial.println("Warning For Temperature");
delay(5000);
digitalWrite(SC, LOW);
Serial.println("Warning For Temperature");
delay(5000);
}
}
if (DHT11.humidity <= 20 || hc == 'r')
{
for (int i = 0; i < 5; i++)
{
digitalWrite(RED, HIGH);
Serial.println("Warning For Humidity");
delay(3000);
digitalWrite(RED, LOW);
Serial.println("Warning For Humidity");
delay(3000);
}
}
}
