Recommendation for microwave occupancy sensor

Recommendation for microwave occupancy sensor

Recommendation for microwave occupancy sensor

(OP)
Hi All -

I'm looking for a room occupancy sensor.  Needs to be small, and able to detect someone entering a room from a good 8m-10m away.  This is for simple interfacing to a microcontroller.

Siemens makes a really nice little microwave sensor, the KMY24, but it doesn't appear to be available from any of the usual US distributors.  Something like that would be ideal.

Any ideas ?

Thanks -

Dean.

RE: Recommendation for microwave occupancy sensor

Most home security motion sensors use a combination of microwave and PIR.  They generally use relay outputs, though.
