Topic: Pachube sensor client (Read 868 times) previous topic - next topic


Hallo zusammen
habe den Sketch "Pachube sensor client" ausprobiert, funktioniert super im Originalzustand.
Habe dann den Analog sensor an analog in 0 durch einen Dallas I2C ersetzt.
Die Werte werden auch auf Patchube angezeigt, jedoch läuft das Programm jetzt extrem langsam.
Es werden nur alle 3 Minuten Daten gesendet.
Habe auch schon mal drei Dallas montiert, ist das gleiche.
Wenn Seriel Monitor aktiviert, wird etwa ein Zeichen pro Sekunde ausgegeben.

Wo liegt der Fehler

Code: [Select]
  Pachube sensor client

This sketch connects an analog sensor to Pachube (http://www.pachube.com)
using a Wiznet Ethernet shield. You can use the Arduino Ethernet shield, or
the Adafruit Ethernet shield, either one will work, as long as it's got
a Wiznet Ethernet module on board.

This example has been updated to use version 2.0 of the Pachube.com API.
To make it work, create a feed with a datastream, and give it the ID
sensor1. Or change the code below to match your feed.

* Analog sensor attached to analog in 0
* Ethernet shield attached to pins 10, 11, 12, 13

// Newer Ethernet shields have a MAC address printed on a sticker on the shield
// fill in your address here:

// if you don't want to use DNS (and reduce your sketch size)

//char server[] = "api.pachube.com";   // name address for pachube API

unsigned long lastConnectionTime = 0;          // last time you connected to the server, in milliseconds
boolean lastConnected = false;                 // state of the connection last time through the main loop
const unsigned long postingInterval = 10*1000; //delay between updates to Pachube.com

void setup() {
// Open serial communications and wait for port to open:
   while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only

// start the Ethernet connection:
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    // DHCP failed, so use a fixed IP address:
    Ethernet.begin(mac, ip);

void loop() {
  // read the analog sensor:
     // int sensorReading = analogRead(A0); 
      int verd = sensors.getTempC(Verdampfer);

  // if there's incoming data from the net connection.
  // send it out the serial port.  This is for debugging
  // purposes only:
  if (client.available()) {
    char c = client.read();

  // if there's no net connection, but there was one last time
  // through the loop, then stop the client:
  if (!client.connected() && lastConnected) {

  // if you're not connected, and ten seconds have passed since
  // your last connection, then connect again and send data:
  if(!client.connected() && (millis() - lastConnectionTime > postingInterval)) {
  // store the state of the connection for next time through
  // the loop:
  lastConnected = client.connected();

// this method makes a HTTP connection to the server:
void sendData(int thisData) {
  // if there's a successful connection:
  if (client.connect(server, 80)) {
    // send the HTTP PUT request:
    client.print("PUT /v2/feeds/");
    client.println(".csv HTTP/1.1");
    client.println("Host: api.pachube.com");
    client.print("X-PachubeApiKey: ");
    client.print("User-Agent: ");
    client.print("Content-Length: ");

    // calculate the length of the sensor reading in bytes:
    // 8 bytes for "sensor1," + number of digits of the data:
       int thisLength = 8 + getLength(thisData);

    // last pieces of the HTTP PUT request:
    client.println("Content-Type: text/csv");
    client.println("Connection: close");

    // here's the actual content of the PUT request:

  else {
    // if you couldn't make a connection:
    Serial.println("connection failed");
   // note the time that the connection was made or attempted:
  lastConnectionTime = millis();

// This method calculates the number of digits in the
// sensor reading.  Since each digit of the ASCII decimal
// representation is a byte, the number of digits equals
// the number of bytes:

int getLength(int someValue)
  // there's at least one byte:
  int digits = 4;
  // continually divide the value by ten,
  // adding one to the digit count for each
  // time you divide, until you're at 0:
// int dividend = someValue /10;
// while (dividend > 0) {
  //  dividend = dividend /10;
   // digits++;
// }
  // return the number of digits:
  return digits;


War das nicht so, daß der digitale Sensor ca 1 Sekunde für die Messung braucht? und darum die Funktionen
      int verd = sensors.getTempC(Verdampfer);
so lange brauchen?
