Features: GY-56 is an ranging sensors module based on VL53L1X chip, which has the characteristics of precise and fast response, and is suitable for various distance measurement applications. 2. This module can accurately measure distances within a ranges of 0.03meters to 2meters, with a measurement error of less than ± 3%. Its working frequency can reach 50Hz, suitable for real-time measurement and dynamic. The GY-56 module is designed to be compact and easy to integrate in projects. Its pin identification is clear, the layout is reasonable, and it is easy to wire and debug. Compared to other types of ultrasonic ranging modules, GY-56 utilizes ranging technology, which is not affected by lighting and environmental noise, has strong adaptability, and highly measurement accuracy. GY-56 is widely used in robot obstacle avoidance, liquid monitoring, object detection, security monitoring and other fields. Such as automatic door control, smart home devices.
