Note, I said humidity sensor, not a humidistat.

I use a PLC to control my system and would like to add humidity control.   The humidistats I've seen merely call a humidifier at a setpoint.
I want the PLC to do the decisions and thus need a sensor.

Appropriate outputs would be 4-20mA, 0-10V, etc.

Thanks

This is what I use, from Hobby Boards:

Output is 1-wire technology.  Obviously you'd need a compatible reading/control instrument.

Thanks Dana, that newportus link was better than anything I'd uncovered to this point.
