blackwidow with temp sensor sht11 ???

hi i found this code for the classic over serial print with usb for my sensor SHT11(the same SHT15).

//Read temperature and humidity values from an SHT1x-series (SHT10,
//SHT11, SHT15) sensor.
#include <SHT1x.h>
// Specify data and clock connections and instantiate SHT1x object
#define dataPin  10
#define clockPin 11
SHT1x sht1x(dataPin, clockPin);

void setup()
{
   Serial.begin(38400); // Open serial connection to report values to host
   Serial.println("Starting up");
}

void loop()
{
  float temp_c;
  float temp_f;
  float humidity;

  // Read values from the sensor
  temp_c = sht1x.readTemperatureC();
  temp_f = sht1x.readTemperatureF();
  humidity = sht1x.readHumidity();

  // Print the values to the serial port
  Serial.print("Temperature: ");
  Serial.print(temp_c, DEC);
  Serial.print("C / ");
  Serial.print(temp_f, DEC);
  Serial.print("F. Humidity: ");
  Serial.print(humidity);
  Serial.println("%");

  delay(2000);
}

and i do this wifi with this code but it doesn't work. why?????????

}

but it doesn't work. why?????????

How are we supposed to know?

What doesn't work? What do you expect to happen? What does happen? What is the difference between what you want and what you get?

i m sorry.well.if i put the code for the wifi when i connect to this in my web browser i cannot see anything.the browser has a problem.If i put another sensor works well.why?

can you tell me if you know what do this code in my wifi session?

    WiServer.print(tempC, DEC);
           WiServer.println("</value> %</data>");
           WiServer.print("<data id=\"5\">\n<value>");

if i put the code for the wifi when i connect to this in my web browser i cannot see anything.the browser has a problem.

What kind of problem?

If i put another sensor works well.why?

Because you are reading the sensor correctly?

Without the wifi shield, are you able to read, and print to the serial monitor, good data from the temp sensor?

can you tell me if you know what do this code in my wifi session?

The first line sends the tempC value to the WiServer class, as a number (not as a string representation of a number). The 2nd and third lines close out some open tags in the html document and add some data to the page that is to be displayed in the browser.

Though, why you are trying to display the temperature followed by a % sign escapes me. As does the use of the DEC argument. Allowing the conversion of tempC to a string seems more reasonable to me.

  1. my browser sed me an error 101.bad connection and i see only this message.

2.in serial print via usb my sendor sht11 works fine.when i told the blackwidow to read the temperature and sent it in html value makes something wrong and i cannot see anything in my browser.only an error 101.bad connection.

why?

3.i copy these 3 lines from another project and i didn't change the % balue.now i write ^C.

Hey - I am not only new here, but am new to the Arduino, and as added insult, I do not yet have my BlackWidow.

With all those disclaimers, I did see some things that I think need tweaking on your HTML and output...

This line:
WiServer.print("

TEMP :

");

contains a close body tag. That's bad if you want anything else to be displayed on the web page. It needs to be the last thing you send, or the browser has a body that only contains your TEMP: text, and then a bunch of malformed HTML.

Combined with this sequence:
WiServer.println(" %");
WiServer.print("<data id="5">\n");

I think you should switch the use of println and print, making the println the LAST thing you do in terms of sending content to the browser, so it's throwing a newline at the end.

I don't know that the last bit really matters, but that tag needs to be the LAST tag you send, for sure.

Good luck ... I hope to be following along with this exercise soon, when my backordered BlackWidow arrives. :slight_smile:
