How it works

3 stages · Explore one step at a time

Step 1 / 3

Initialize and calibrate

Use ST’s API to initialize the sensor and apply required reference, offset and cover-glass calibration.

Step 2 / 3

Measure reflected light

The emitter and receiver collect timing information during the chosen measurement budget.

Step 3 / 3

Read distance and status

Wait for data-ready, read the result and clear the interrupt. Reject invalid or out-of-range samples.
