SAS-1 Passive Acoustic Detector (PAD)
The SAS-1 passive acoustic detection system is a very afforable and
easy to install alternative to "in pavement" magnetic loops.
The SAS-1 delivers reliable multi-lane vehicle detection and traffic flow measurements from a non-intrusive roadside mounting position. Each SAS-1 sensor head can accurately monitor up to five freeway or midblock lanes.
The SAS-1 passive acoustic detection system provides very low power operation and flexible communication modes critical for solar powered sensor stations. Wireless communication options are available for the SAS-1 eliminating the need to install long and expensive cable conduit runs.
