This module features an RCWL-9620 ultrasonic distance measurement chip with a 16mm probe, achieving a ranging accuracy of 2cm to 450cm (accuracy up to ±2%). This sensor determines the distance to a target by measuring time lapses between the transmitting and receiving of the pulse signal, allowing users to directly obtain the distance value through IO control mode. It is ideal for applications in robotics obstacle avoidance, fluid level detection, and other scenarios that require precise measurements.
