The SparkFun Garmin LIDAR-Lite v4 Qwiic LED Distance Measurement Sensor sends out an infrared beam and measures the time it takes to be reflected. The LIDAR-Lite v4 utilizes LEDs rather than a laser for this iteration and is inherently eye-safe under normal usage.
The built-in nRF52840 microcontroller runs a pre-loaded “out of the box” application to calculate the distance between itself and an object in front of it. The equipped nRF52840 also allows developers to create custom applications to expand on the “out of the box” functionality or connect to an external micro-controller running a custom user application.
- 1cm Resolution
- Measurement repeatability:
- As measured indoors to a 90% reflective target
- 1cm is equivalent to one standard deviation
- Using “high accuracy” mode, with averaging:
- +/- 1cm to 2 meters
- +/- 2cm to 4 meters
- +/- 5cm to 10 meters
