4-20HR-MaxSonar-WRMI - ultrasonic distance sensor MB7489 (50-500cm)

ST Microelectronics\' compact Time-of-Flight (TOF) sensor uses a 940 nm laser to precisely measure distances from 1 mm to 1.2 m with a resolution of 1 mm. It supports an I²C interface, has an XSHUT input for shutdown and a GPIO1 output for object detection, and is compatible with voltages from 2.6 to 5.5 V thanks to a built-in regulator and logic level converter.
