The VCNL4010, VCNL4020, and VCNL4020X01 are fully integrated proximity and ambient light sensors. Fully integrated means they contain the infrared emitter and photo detector for proximity, an ambient light sensor, a signal processing IC, and I2C communication interface. VCNL4020X01 is qualified for automotive applications. It has a maximum operating temperature of 105 ˚C. The VCNL3020 supports only proximity sensing; it does not contain an ambient light sensor. With full 16-bit resolution for both the proximity and ambient features, user-defined interrupt levels, and multiple packaging options, the VCNL portfolio will fulfill your requirements.
