DESCRIPTION

The VCNL4010 is a fully integrated proximity and ambient

light sensor. Fully integrated means that the infrared emitter

is included in the package. It has 16 bit resolution. It

includes a signal processing IC and features standard I2C

communication interface. It features an interrupt function.

APPLICATIONS
