DHT11接入小爱后经常查询不到温度,湿度查询不到,求解
DHT11接入小爱同学后,偶尔能查询到温度,多数时候提示与设备沟通失败,blinker APP中显示是正常的。湿度信息从来没有查询到过,请教问题所在代码如下:
#define BLINKER_WIFI
#define BLINKER_MIOT_SENSOR
#define BLINKER_DUEROS_SENSOR
#define BLINKER_ALIGENIE_SENSOR
#define BLINKER_ESP_SMARTCONFIG
#include <Blinker.h>
#include <DHT.h>
char auth[] = "e3f1db5684864"; // Blinker APP中添加设备时生成的Secret Key
BlinkerNumber HUMI("humi");
BlinkerNumber TEMP("temp");
#define DHTPIN 5
#define DHTTYPE DHT11 // DHT 11
DHT dht(DHTPIN, DHTTYPE);
uint32_t read_time = 0;
int humi_read = 0;
float temp_read = 0;
void heartbeat()
{
HUMI.print(humi_read);
TEMP.print(temp_read);
}
void miotQuery(int32_t queryCode)
{
BLINKER_LOG("MIOT Query codes: ", queryCode);
switch (queryCode)
{
case BLINKER_CMD_QUERY_ALL_NUMBER :
BLINKER_LOG("MIOT Query All");
BlinkerMIOT.temp(temp_read);
BlinkerMIOT.humi(humi_read);
BlinkerMIOT.print();
break;
default :
BlinkerMIOT.temp(20);
BlinkerMIOT.humi(20);
BlinkerMIOT.print();
break;
}
}
void dataStorage()
{
Blinker.dataStorage("temp", temp_read);
Blinker.dataStorage("humi", humi_read);
}
void duerQuery(int32_t queryCode)
{

break;

BlinkerDuerOS.temp(temp_read);
BlinkerDuerOS.print();
break;

BlinkerDuerOS.humi(20);
BlinkerDuerOS.print();
break;
}
}
void aligenieQuery(int32_t queryCode)
{
BLINKER_LOG("AliGenie Query codes: ", queryCode);
switch (queryCode)
{
case BLINKER_CMD_QUERY_ALL_NUMBER :
BLINKER_LOG("AliGenie Query All");
BlinkerAliGenie.temp(temp_read);
BlinkerAliGenie.humi(humi_read);
BlinkerAliGenie.print();
break;
default :
BlinkerAliGenie.temp(20);
BlinkerAliGenie.humi(20);
BlinkerAliGenie.print();
break;
}
}
void dataRead(const String & data)
{
BLINKER_LOG("Blinker readString: ", data);
Blinker.vibrate();
uint32_t BlinkerTime = millis();
Blinker.print("millis", BlinkerTime);
}
void setup()
{
Serial.begin(115200);
BLINKER_DEBUG.stream(Serial);
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, LOW);
Blinker.begin(auth);
Blinker.attachData(dataRead);
Blinker.attachHeartbeat(heartbeat);
Blinker.attachDataStorage(dataStorage);
BlinkerMIOT.attachQuery(miotQuery);
BlinkerDuerOS.attachQuery(duerQuery);
BlinkerAliGenie.attachQuery(aligenieQuery);
dht.begin();
}
void loop()
{
Blinker.run();
if (read_time == 0 || (millis() - read_time) >= 2000)
{
read_time = millis();
float h = dht.readHumidity();
float t = dht.readTemperature();
if (isnan(h) || isnan(t)) {
BLINKER_LOG("Failed to read from DHT sensor!");
return;
}
float hic = dht.computeHeatIndex(t, h, false);
humi_read = h;
temp_read = t;
BLINKER_LOG("Humidity: ", h, " %");
BLINKER_LOG("Temperature: ", t, " ℃");
BLINKER_LOG("Heat index: ", hic, " ℃");
}
}
float humi_read, temp_read; 也是不行 molun 发表于 2020-8-14 16:34
float humi_read, temp_read; 也是不行
换个dht11专用库试试 看串口调试信息 这个问题我也遇到了 楼主解决了吗
