Product description: Gravity - TRIG URM09 ultrasonic distance sensor - DFRobot SEN0388
Ultrasonicdistance measuringmodule produced byDFRobotwith integratedURM09chip. It detects objects at a distancefrom 2 cm to 500 cm. The distance is determined with a resolution of1 cmwith an accuracy of1%. The sensor can be powered from3.3 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 a car reversing signal or a smart doorbell.
Compatible with Arduino and Raspberry Pi
The manufacturer has prepared a detaileduser guidewhich includes sample program code for Arduino IDE environment andURM09_Trig libraryfor MakeCode graphic editor.
