GY-530 VL53L0X Time Of Flight Distance Measurement Sensor

GY-530 VL53L0X Time Of Flight Distance Measurement Sensor Module is a cutting-edge sensor solution that utilizes ST Microelectronics’ patented FlightSense™ Technology to accurately measure absolute distance regardless of the target’s reflectivity. Unlike traditional infrared sensors that rely on intensity, the VL53L0X calculates distance by measuring the time it takes for a laser pulse to travel to the target and return (Time-of-Flight or ToF). This method offers superior performance, speed, and reliability. Consequently, the GY-530 module eliminates common issues like cross-talk and ambient light interference. Furthermore, its small form factor and low power consumption make it ideal for use in mobile devices, robotics, and complex automation projects, giving your applications millimeter-accurate range detection.

Key Features:

• Time-of-Flight (ToF) Technology: Measures absolute distance in millimeters up to 2 meters, offering excellent accuracy independent of target color or surface.
• Integrated 2.8V Regulator: The GY-530 module incorporates a voltage regulator, allowing seamless operation from a wide range of host supply voltages (typically 3.3V to 5V).
• I²C Interface: Communicates through a simple, two-wire I²C interface, simplifying integration with microcontrollers like Arduino, Raspberry Pi, and ESP32.
• Integrated Laser: Uses a 940 nm VCSEL (Vertical Cavity Surface Emitting Laser) that is totally invisible to the human eye, ensuring Class 1 laser safety.
• Fast Ranging: Achieve measurement speeds up to 50 Hz, which allows for real-time tracking and control applications.
