Gravity - TRIG URM09 ultrasonic distance sensor - DFRobot SEN0388

Ultrasonic distance measuring module produced by DFRobot with integrated URM09 chip. It detects objects at a distance from 2 cm to 500 cm. The distance is determined with a resolution of 1 cm with an accuracy of 1%. The sensor can be powered from 3.3 V to 5.5 V DC. Small size, high measurement accuracy, Plug&Play support and wide measurement range make the module widely applicable in projects whose mission is to avoid obstacles, warn about crossing the safety line or applications such as car reversing signal.
