API for Grove Ultrasonic Ranger. More...
This Grove Ultrasonic sensor is a non-contact distance measurement module which is compatible with the Grove system. It is designed for easy modular project usage with industrial performance. Detection ranges from 3 cm (1.2") to 4 m (13'1.5") and works best when the object is within a 30 degree angle relative to the sensor.
