Gravity: URM09 Ultrasonic Sensor (I²C)

7 items left

DFRobot URM09 is an ultrasonic sensor specifically designed for fast ranging and obstacle avoidance applications. Its measuring frequency can reach up to 50Hz. The sensor adopts built-in temperature compensation and I2C communication. There are three measurement ranges designed for programs to select: 150cm, 300cm and 500cm. Please note that a shorter range will provide a shorter ranging cycle and lower sensitivity. You may need to set it according to your actual use. Besides, the sensor is equipped with on-board LDO, which is able to avoid performance attenuation within the power supply range.
