Overview
JRT DIY Digital Laser Meter Inspection Sensor 150 m Range Finder Measure Module with USB is a laser distance sensor module designed for OEM integration. This Laser Meter Inspection Sensor measures 0.03-150 m with +/-3 mm accuracy and 1 mm resolution, using a red Class II laser (620-690 nm, <1 mW). It supports meter/inch/feet units, offers USB/TTL digital output, and operates from a DC 2.0-3.3 V supply. Typical measuring time is 0.4-4 s at 3 Hz. The compact module measures 64 x 40 x 18 mm and weighs about 13 g. Certificates: ISO9001, CE, RoHS, FCC.
