获取BME280传感器数据并上传到云端

coloz

这是在之前的示例基础上更近一步，添加历史数据存储：

效果如图：


[mw_shl_code=cpp,true]#define BLINKER_WIFI
#include <Blinker.h>

char auth[] = "xxxxxxxxxxxx";
char ssid[] = "xxxxx";
char pswd[] = "xxxxxxxx";

BlinkerNumber TEMP("temp"); // Temperature
BlinkerNumber HUMI("humi"); // Humidity
BlinkerNumber PRES("pres"); // Pressure
BlinkerNumber ALTI("alti"); // Altitude

int tempValue;
int humiValue;
int presValue;
int altiValue;

// Download Adafruit-BMP085-Library library here:
// https://github.com/adafruit/Adafruit_BME280_Library
// https://github.com/adafruit/Adafruit_Sensor
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>

#define SEALEVELPRESSURE_HPA (1013.25)

Adafruit_BME280 bme;

void dataRead(const String &data)
{
    BLINKER_LOG("Blinker readString: ", data);

    Blinker.vibrate();

    uint32_t BlinkerTime = millis();

    Blinker.print("millis", BlinkerTime);
}

void dataStorage()
{
    readSensor();
    Blinker.dataStorage("temp", tempValue);
    Blinker.dataStorage("humi", humiValue);
    Blinker.dataStorage("pres", altiValue);
}

void heartbeat()
{
    readSensor();
    TEMP.print(tempValue);
    HUMI.print(humiValue);
    PRES.print(presValue);
    ALTI.print(altiValue);
}

void readSensor()
{
    tempValue = bme.readTemperature();
    humiValue = bme.readHumidity();
    presValue = bme.readPressure();
    altiValue = bme.readAltitude(SEALEVELPRESSURE_HPA);
}

void setup()
{
    Serial.begin(115200);
    BLINKER_DEBUG.stream(Serial);

    pinMode(LED_BUILTIN, OUTPUT);
    digitalWrite(LED_BUILTIN, LOW);

    Blinker.begin(auth, ssid, pswd);
    if (!bme.begin())
    {
        BLINKER_LOG("Could not find a valid BME280 sensor, check wiring!");
        while (1)
        {
            delay(100);
        }
    }
    readSensor();
    Blinker.attachData(dataRead);
    Blinker.attachHeartbeat(heartbeat);
    Blinker.attachDataStorage(dataStorage);

}

void loop()
{
    Blinker.run();
}[/mw_shl_code]

学习了，受益匪浅

轻轻海风

ESP8266 NodeMCU 连接3.3V的BME280连接图SCB引脚不需要接上拉10K电阻，因为片内已经有了上拉电阻了。
