Ultrasonic Distance Unit I/O (RCWL-9620) photo

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… (M5Stack U098-B2)
