【arduino】温湿度检测模块检测

#include<dht11.h>
dht11 DHT11;
#define DHT11PIN 2
void setup()
{
Serial.begin(9600);
Serial.print("My name is : ZhongZiJie");
}
void loop()
{
Serial.println("\n");
int chk = DHT11.read(DHT11PIN);
Serial.print("Read sensor:");
switch(chk)
{
case DHTLIB_OK:
Serial.println("OK");
break;
case DHTLIB_ERROR_CHECKSUM:
Serial.println("Checksum error");
break;
case DHTLIB_ERROR_TIMEOUT:
Serial.println("Time out error");
break;
default:
Serial.println("Unknown error");
}
Serial.print("Humidity(%):");
Serial.println(DHT11.humidity);
Serial.print("Temperature(oC):");
Serial.println(DHT11.temperature);
delay(1000);
}

就想问下如果环境湿度高于58，LED灯闪烁，否则LED灯熄灭,那我还要加什么?
