ToF Distance Sensor RAKwireless RAK12014 (ST VL53L0X)

RAKwireless RAK12014 is a compact Time-of-Flight (ToF) sensor module for WisBlock when you need reliable distance measurement without ultrasonic transducers or camera systems. It is based on the STMicroelectronics VL53L0X, a ToF laser-ranging module that reports absolute range.

The VL53L0X uses an invisible 940 nm VCSEL emitter along with internal infrared filtering. In practice, this improves robustness under changing ambient light and helps when the sensor is mounted behind cover glass (where optical crosstalk can otherwise degrade performance).

The provided specs mention both up to 1.5 m and up to 2 m. A store-accurate way to present this is: up to 2 m, typically ~1.5 m depending on target reflectivity and setup, which aligns with both statements.

Realistic use cases include:

Robotics and mobile platforms for obstacle distance detection and simple navigation/stop logic.

Industrial automation, measuring distance to parts/fixtures and detecting presence within a threshold.

Touchless proximity triggers for devices and interfaces.

Low-power IoT nodes, sampling distance periodically or using interrupts to reduce active time.

Integration is straightforward via I2C, with additional XSHUTDOWN (reset) and interrupt GPIO. The module operates from 2.6 V to 3.5 V and lists current consumption from 3 µA to 19 mA depending on sleep vs. active ranging.
