Point the laser beam and presto, ultrasonics calculate the distance. Also calculates the area and the volume. 3' to 60' range. 0.5% accuracy. Big 1/2" LCD readout. Operates on 9V battery (not included). Size 2-3/4" x 5-3/4". Weighs 5 pounds. Utilizes 1 mW class 2 laser. 130' laser range. These operate on a 670nm wavelength. RoHS compliant.

This pre-assembled sensitive ultrasonic motion detector circuit uses a quartz crystal to lock the detector frequency for maximum stability and reliability. It was originally designed for use as a parking distance detector. It provides a digital, analog and relay output. Features; Buzzer output: fast/slow/continuous. Distance indication with 3-LED-bar. Adjustable alarm distance. LED alarm indicator. Dry contact NO/NC relay. Applications: robot projects, object detection, distance measuring, parking aid, security systems, etc. Range: 0.66 to 8 ft. Frequency 40kHz. Operates on 12VDC/200ma.
