Description
Unit Ultrasonic-IO is a GPIO interface ultrasonic distance measurement sensor. The hardware uses the RCWL-9620 ultrasonic distance measurement single-chip combined with a 16 mm probe, capable of achieving precise distance measurement within the range of 2 cm-450 cm (accuracy up to ±2%). After the controller sends a trigger signal, the sensor outputs a pulse duration corresponding to the sound wave reflection time, and the distance can be calculated from this data. The IO control method gives this sensor an extremely fast response speed, making it very suitable for applications such as robot obstacle avoidance and liquid level detection.
Note: When measuring distances greater than 3.5m, the distance measurement data response will be slightly delayed.
