VL53L0X TOF Laser Distance Sensor Module - I2C Interface

The module accepts a wide input voltage range from 2.6V to 5.5V DC. It features an onboard 2.8V linear regulator that powers the sensor core, making it compatible with both 3.3V and 5V microcontroller logic levels without requiring an external level shifter.

Communication is via the I2C (Inter-Integrated Circuit) protocol. The module provides dedicated SDA (data) and SCL (clock) pins. The default I2C address is 0x29, but it can be changed programmatically if multiple sensors are used on the same bus. Standard Arduino Wire or platform-specific I2C libraries can be used.

The VL53L0X can measure absolute distances up to approximately 2 meters under optimal conditions. Actual maximum range can be influenced by target reflectance, ambient light, and cover glass material. For best performance on dark or highly reflective surfaces, refer to the sensor's timing budget configuration in the datasheet.

Yes. The module uses a 940nm Vertical-Cavity Surface-Emitting Laser (VCSEL) which is classified as a Class 1 laser product. This wavelength is invisible to the human eye and is considered eye-safe under normal operating conditions, requiring no special safety precautions during handling or integration.

While the VL53L0X includes internal IR filters for improved ambient light immunity, performance can degrade in direct, intense sunlight due to photon saturation of the SPAD receiver. It is best suited for indoor applications or shaded outdoor environments. For full-sun operation, consider sensors with higher ambient light rejection specifications.
