如下图串口通信显示，温湿度总是显示169%和-13.6这两个明显错误的数字。
不知道有没有小伙伴出过类似问题的，求解答，程序如下。#define BLINKER_WIFI
#include <Blinker.h>
#include <DHT.h>
char auth[] = "";
char ssid[] = "";
char pswd[] = "";
BlinkerNumber HUMI("num-ec7");
BlinkerNumber TEMP("num-mio");
#define DHTPIN 2
#define DHTTYPE DHT11 // DHT 11
DHT dht(DHTPIN, DHTTYPE);
float humi_read = 0, temp_read = 0;
void heartbeat()
{
HUMI.print(humi_read);
TEMP.print(temp_read);
}
void setup()
{
Serial.begin(115200);
BLINKER_DEBUG.stream(Serial);
BLINKER_DEBUG.debugAll();
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, LOW);
Blinker.begin(auth, ssid, pswd);
Blinker.attachHeartbeat(heartbeat);
dht.begin();
}
void loop()
{
Blinker.run();
float h = dht.readHumidity();
float t = dht.readTemperature();
if (isnan(h) || isnan(t))
{
BLINKER_LOG("Failed to read from DHT sensor!");
}
else
{
BLINKER_LOG("Humidity: ", h, " %");
BLINKER_LOG("Temperature: ", t, " *C");
humi_read = h;
temp_read = t;
}
Blinker.delay(2000);
}
