La crosse WS- 2300

I have a anemometer (wind speed sensor) from an La Crosse weather station (WS-2300) (up to 16 wind directions) and
Rain Gauge for WAS 2300-16-series. I’d like to connect it to my arduino.

It uses a standard RJ11 jack to transmit data. I opened it (wind speed sensor)- photo, up and saw that the RJ-11 pin-out is as followed:

1 - serial I / O
2 - VDD
3 - Regulator CE (Chip Enable)
4 - GND

Rain Gauge used Reed switch RJ-11 pin-out is as followed>

1 - DATA
4 - GND

How would I go about connecting it to my arudino, and then reading what’s being sent over the serial line?

thanks

You apparently did not search the forum, check - http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1286087094

Thanks,

but this does not help me much. If I look at other post is still anemometer connected to ovn pin, and wind vane to another. How is here?

tnx

1 - serial I / O 2 - VDD 3 - Regulator CE (Chip Enable) 4 - GND

There will be pulses from line 1, probably a square wave. You could use an interrupt routind to count these pulses. See - http://arduino.cc/en/Reference/AttachInterrupt

The minimal code should be like this

volatile unsigned long counter = 0;

void setup()
{
  Serial.begin(115200);
  attachInterrupt(0, wind, RISING);   // IRQ 0 == PIN 2
}

void loop()
{
  if (millis() - last > 1000)  // display counter once per second
  {
    Serial.println(counter);
    last = millis();
  }
}

void wind()
{
  counter++;
}
