SparkFun Qwiic 4m Distance Sensor with VL53L1X


SparkFun Distance Sensor Breakout - 4 Meter, VL53L1X (Qwiic) [SEN-14722]	SparkFun Distance Sensor - 1.3 Meter, VL53L4CD (Qwiic)[SEN-18993]

The VL53L1X is a Time Of Flight (ToF) sensor that use a VCSEL (vertical cavity surface emitting laser) to emit a class 1 IR laser and time the reflection to the target. What does all this mean? Using the VL53L1X, you can measure the distance to an object up to 4 meters away with millimeter resolution! That’s pretty incredible.

We’re far from done: The VL53L1X is a highly complex sensor with a multitude of options and configurations. We’ve written example sketches that allow you to read the distance, signal rate, and range status. Because STMicroelectronics has chosen not to release a complete datasheet we are forced to reverse engineer the interface from their example code and I2C data stream captures. If you’re into puzzles we could use your help to make the library better!

We’ve found the precision of VL53L1X sensor to be 1mm but the accuracy is around +/-5mm.

SparkFun labored with love to create this code. Feel like supporting open source hardware? Buy a breakout board from SparkFun!

Note: The VL53L4CD is the cousin of VL53L1X. Overall, the sensor functions the same except for a few differences in the specifications. We've also found the precision of VL53L4CD sensor to be 1mm but the accuracy is around +/-7mm (white target: 88%, indoor, no infrared).
