VCNL4000 Proximity / Ambient Light Sensor
Fully integrated sensor including infrared emitter, ambient light sensor, proximity photo-diode and signal processing

The VCNL4000 is a fully integrated proximity and ambient light sensor. "Fully integrated" means the sensor not only includes a PIN photodiode for proximity, an ambient light sensor, and signal processing IC, it also includes an infrared emitter. Having all the components in one package greatly simplifies the design process.

  • No mechanical barriers required; no crosstalk concerns
  • Proximity range up to 20 cm (7.9 in)
  • Programmable LED drive current: 10 mA to 200 mA in 10 mA steps
  • Programmable measurement rate from 1 Hz to 250 Hz
  • 16 bit resolution with I2C interface
  • Ambient light sensing from 0 klx to 13 klx with 0.33 lx resolution
  • Determine presence of an object to turn on / off display
  • Measure ambient light to optimize display brightness
  • Smart phones, digital cameras, tablet PCs, LCD displays, event-driven industrial controls
