Connect DHT11 Sensor to Internet/Adafruit IO Programming Tutorial

Описание: This video is an expansion to my IFTTT Applet contest submission that shows you how to connect an ESP8266 with a DHT11 sensor to Adafruit IO.

Paste this link into your preferences to add the ESP boards:

Here is the code for the sketch I wrote in the video. You still need the config.h file from the 00_publish example though:

NOTE: Angled brackets are not allowed in YouTube descriptions so look at the example for where you need to put them and what type. Here I've inserted "[angled bracket]" replacing the actual bracket.

/************************** Configuration ***********************************/

// edit the config.h tab and enter your Adafruit IO credentials
// and any additional configuration needed for WiFi, cellular,
// or ethernet clients.
#include "config.h"
#include "DHT.h"

#define DHTPIN 14
#define DHTTYPE DHT11
/************************ Example Starts Here *******************************/

// this int will hold the current count for our sketch
DHT dht(DHTPIN, DHTTYPE);

// set up the 'counter' feed
AdafruitIO_Feed *testtemp = io.feed("testtemp");

void setup() {

// start the serial connection
Serial.begin(115200);
Serial.println(F("DHTxx test!"));

dht.begin();

// wait for serial monitor to open
while(! Serial);

Serial.print("Connecting to Adafruit IO");

// connect to io.adafruit.com
io.connect();

// wait for a connection
while(io.status() [angled bracket] AIO_CONNECTED) {
Serial.print(".");
delay(500);
}

// we are connected
Serial.println();
Serial.println(io.statusText());

}

void loop() {

// io.run(); is required for all sketches.
// it should always be present at the top of your loop
// function. it keeps the client connected to
// io.adafruit.com, and processes any incoming data.
io.run();

float t = dht.readTemperature();

// save count to the 'counter' feed on Adafruit IO
Serial.print("sending -[angled bracket] ");
Serial.println(t);
testtemp-[angled bracket]save(t);

// Adafruit IO is rate limited for publishing, so a delay is required in
// between feed-[angled bracket]save events. In this example, we will wait three seconds
// (1000 milliseconds == 1 second) during each loop.
delay(5000);
