Description

The Garmin LIDAR-Lite v3 utilizes a 905 nm laser-based time-of-flight (ToF) principle for precise optical distance measurement. Its single-chip signal processing solution minimizes hardware complexity, resulting in a compact and lightweight sensor module ideal for space-constrained mobile applications. The sensor is highly configurable, allowing users to optimize the trade-off between measurement accuracy, maximum operating range, and acquisition speed to suit specific project requirements.

Designed for integration into drones, robotic platforms, and unmanned vehicles, the LIDAR-Lite v3 provides reliable proximity sensing and obstacle detection. It requires an external 5V power source and a microcontroller to operate, communicating seamlessly via I2C or PWM output. The sensor’s robust construction and consistent performance make it a foundational building block for advanced navigation and automation systems.

Frequently Asked Questions

What is the operating voltage and current requirement for the LIDAR-Lite v3?

The LIDAR-Lite v3 operates at a nominal 5V DC. During a distance acquisition, it typically draws approximately 105 mA. A stable 5V power supply is required for reliable operation and accurate measurements.

How do I communicate with the sensor, and what interfaces are supported?

The sensor supports two primary communication methods: I2C and PWM. The I2C interface allows for full configuration and data reading via a microcontroller. The PWM output provides a direct pulse-width signal proportional to the measured distance, which can be read by a microcontroller's input capture or timing functions.

Can the sensor's performance be adjusted for different applications?

Yes, the LIDAR-Lite v3 is user-configurable. You can adjust key parameters to balance performance. For example, you can prioritize faster measurement times (up to 500 Hz), extend the maximum detection range to 40 meters, or optimize for higher accuracy (±2.5 cm), depending on your specific needs for speed, range, or precision.

What is the minimum and maximum distance this sensor can measure?

The sensor has a specified measurement range from 5 centimeters (0.05 meters) up to a maximum of 40 meters. Reliable detection within this range depends on target reflectivity and environmental conditions. The minimum distance is critical for close-proximity object detection in robotics.
