I have been looking for a good doppler velocity sensor and since Geotivity is gone I have not found one. I have a Sigma AV sensor and I am wondering if anyone knows how "smart" the sensor is. The wiring diagram looks to have 12V power with two pairs of send/receive wires. Has anyone used this with a Campbell datalogger and know if the signal is analog or digital?
If anyone knows of another good velocity sensor that will work I would love to know that as well.
Thanks.
