GY-53 VL53L0X Laser ToF Flight Time Range Sensor Module

GY-53 VL53L0X Laser ToF Flight Time Range Sensor Module integrates the sophisticated VL53L0X sensor from STMicroelectronics, providing precise, non-contact distance measurement up to two meters based on the Time-of-Flight (ToF) principle. This advanced module measures the time required for a laser pulse to travel to an object and return, offering significantly better absolute accuracy compared to traditional ultrasonic or infrared proximity sensors. Consequently, you can achieve millimeter-level precision regardless of the target’s surface reflectance, a major advantage over older technologies. Furthermore, its small footprint and I²C communication protocol make integration into compact embedded systems straightforward and quick. Therefore, engineers utilize this module widely for robotics, automated systems, and interactive displays requiring rapid and reliable ranging capabilities.

Key Features:

• Time-of-Flight (ToF) Principle: The sensor determines distance by measuring the time a laser pulse travels, delivering absolute range measurement independent of target color or texture.
• Integrated 940 nm VCSEL: This module uses an eye-safe, invisible Class 1 laser emitter, ensuring safe operation in consumer and industrial environments.
• High-Speed I²C Interface: The module communicates through a standard two-wire interface (I²C), simplifying connectivity with virtually all microcontrollers.
