I have a anemometer (wind speed sensor) from an old La Crosse weather station (WS-2317) I used to have. I'd like to connect it to my arduino.
It uses a standard RJ11 jack to transmit data. I opened it up and saw that the RJ-11 pin-out is as followed:
1 - serial I / O
2 - VCC
3 - Regulator CE (Chip Enable)
4 - GND
How would I go about connecting it to my arudino, and then reading what's being sent over the serial line?
thanks
I would start here:
That website shows how to connect the base station to a server. My base station is broken, so I was wondering if I could just connect the sensor directly.
Basically, I want to know what I should connect the four RJ11 pins to. And then how can I see what the sensor is sending over serial? Even if all I see are the 1's and 0's.
1 - serial I / O
2 - VCC
3 - Regulator CE (Chip Enable)
4 - GND
It's too bad the base station is broken else you could snoop on the 4 lines to see what was going on in normal operation.
If you have any test instruments I'd recommend powering it up by applying a voltage to VCC and GND (3.3V is probably safe to start with using a current-limited power supply) and keeping the Regulator CE line grounded. Then switch the CE line to 3.3V and see if the current draw changes or the serial I/O line starts to toggle.
If nothing happens at 3.3V then kick it up to 5V and hope for the best. There is the potential to damage things here so maybe a bit more research is warranted to see if someone has already figured this out.

Thanks! I'll try that.
Edit: Nothing seems to happen. I'm starting to think that it's broken as well. (Or maybe I fried it...)
I'm think I'm going to try and build my own anemometer with a magnet and a reed switch.
