The VL6180x three-in-one optoelectronic module integrates an IR VSEL (vertical-cavity surface-emitting laser) infrared vertical cavity surface emitting laser source, proximity sensor, and ambient light sensor (ALS).
The VL6180X module implements a proximity sensor using the time-of-flight (ToF) measurement principle; the VL6180X includes a SPAD (Single Photon Avalanche Diode) detector array that detects the time at which a single photon is transmitted from the target to the target and back to the module, calculated in conjunction with the signal amplitude. The actual distance, independent of the reflectivity of the object, this actual distance measurement capability can also produce simple but reliable one-dimensional gesture control.
The ambient light sensor also has high sensitivity and precision under ultra-low light, wide sensing dynamic range, and ambient light (Lux) corrected output.
