DESCRIPTION:
The CS494000 WITSonar^TM Sensor is the lowest cost Ultrasonic sensor for distance measurements. This sensor can be used for any number of applications that require distance measurements between moving or stationary objects, such as robotics, security systems, or as a replacement for infrared sensors. It has an activity status LED and it uses only one I/O pin. The WITSonar^TM sensor measures distance using ultrasonic technology. An ultrasonic sound burst, well above the human hearing range, is transmitted from the unit and distance-to-target is determined by measuring the time required for an echo to return. The output from the WITSonar^TM sensor is a variable-width pulse that corresponds to the distance to the target. Interfacing to the C Stamp^TM microcontroller is easy: a single I/O pin is used to trigger the WITSonar sensor, and to receive its output pulse equivalent to the distance-to-target. An onboard header allows the WITSonar^TM to be plugged into a solderless breadboard or to be connected to its host through a standard three-pin servo extension cable. The sensor can be triggered using the PULSOUT command and its output can be received using the PULSIN command. The WITSonar^TM Sensor is compatible with the C Stamp microcomputer’s supplies and signal levels, and it has holes for easy bolt or screw based mounting.
