GY56 VL53L0X Infrared Ranging Sensor Module Overview The GY56 VL53L0X is a compact digital infrared timeofflight ranging sensor module that provides direct distance output with low power consumption and easy installation. It measures the time between emitted infrared light and the reflected to calculate distance, then delivers the result via serial or I2C communication. Key benefits Accurate distance readings using timeofflight infrared measurement for reliable proximity detection. Low power operation at 3 to 5 volts for batterypowered and embedded projects. Small footprint and simple wiring for fast integration into prototypes and finished products. Flexible communication options with TTL UART and I2C interfaces, supporting common microcontrollers and development boards. Configurable alarms and outputs allow the module to act as a distancetriggered switch without constant external processing. Main features Sensor: VL53L0X timeofflight infrared ranging sensor. Supply voltage: 3 to 5 V. Communication modes: TTL UART (serial) and I2C (2wire). UART baud rates: 9600 bps and 115200 bps, configurable. Continuous output modes: two inquiry methods available; settings can be retained after power loss. Alarm outputs: settable upper and lower distance thresholds; module provides a digital output when an object is detected within the set range. I2C address configuration: internal address can be changed so multiple sensors can share the same bus. Technical and performance notes Distance measurement is calculated by emitting infrared light and timing the to the onboard MCU, which outputs the distance directly over the selected interface. Low power design makes the module suitable for portable and alwayson applications. Compact module size simplifies mounting in small enclosures or robotics platforms. UART and I2C modes give flexibility for both simple serial connections and multidevice I2C networks. Compatibility Works with standard 3 to 5 V microcontrollers and development boards. Compatible with common platforms that support TTL serial or I2C communication. I2C address change support enables multiple GY56 modules on a single bus for multipoint distance sensing. Practical applications Obstacle detection for small robots and autonomous vehicles, using the alarm output for immediate collision avoidance. Presence sensing and object counting at machine infeed or conveyor points, configured to trigger when objects enter a defined distance window. Range measurement for interactive installations or DIY projects where compact size and low power are required. What makes it stand out Direct distance output and dual communication options reduce firmware complexity and speed integration. Configurable alarms and addressable I2C support allow scalable multisensor systems without additional multiplexing hardware. Retained settings after power loss simplify deployment in devices that may be powered intermittently. Includes GY56 module with VL53L0X sensor and breakout circuitry for TTL UART and I2C connections. Note Follow standard wiring for 3 to 5 V power and connect UART or I2C lines to matching logic levels on your controller. Adjust UART baud rate or I2C address through the module configuration options as required.
