AED 59.00

Low stock


DFRobot URM09 is an ultrasonic sensor specifically designed for fast-ranging and obstacle avoidance application. 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 can avoid performance attenuation within the power supply range.
