Dual Lane Vehicle Detector & Classifier
The AutoSense AS825 is available as AS-825-UDK-H, and AS825-EDK-H. The AS825 combines dual beams (i.e. two separate planes of detection) with an unsurpassed scanning rate of 360 scans per second per beam with angular resolution of 0.667 degrees and 60 degrees field of view. The classification parameters are fully configurable and can be defined in terms of vehicle length, vehicle height, vehicle width, profile and tow bar detection.
The AS825 is supplied in a Nitrogen-filled, hermetically sealed package, which ensures high reliability and long life time. The product is a Class-1 laser (Eye safe) and is equipped with window heater, which allows it to operate down to -40 degree C.
The AS825 communicates over RS-422 and can be set to communicate vehicle class and vehicle presence over a low speed serial interface or alternatively, range and intensity for every single pixel in real time over a high speed serial interface.
