Mouser offers proximity and ambient light sensor from Vishay

Distributor Mouser Electronics is now stocking a proximity and ambient light sensor from Vishay. The VCNL4100 combines a high-power infra red (IR) emitter, photo detectors for proximity and ambient light, a signal-processing IC, and an 8-/16bit ADC for proximity and presence detection up to 1m for smart home, robotics, lighting control, and vehicle detection applications.

The sensor offers a five-fold increase in proximity detection over previous-generation devices, says the company. The integrated long-distance proximity sensor, ambient light sensor, and 940nm IR-emitting diode eliminates the need for additional light barriers and optical alignment of the IR emitter and photo diode. The device’s small outline saves space and offers more options as to where and how the sensor can be located.

The 16bit, high-resolution ambient light sensor can be used in dark or high-transparency lens design. They offer individual programmable high- and low-threshold interrupt features. For the 8bit proximity-sensing function, the sensor has a built-in intelligent cancellation scheme that eliminates background light issues. The device’s smart persistence scheme prevents false judgment of proximity sensing due to ambient light noise.

The VCNL4100 provides temperature compensation of -40 to +85 degree C to keep the output stable under changing temperature. Designers can operate proximity and ambient light sensor functions via the device’s I2C (SMBus-compatible) interface protocol. The device operates on a supply voltage range of 2.5 to 3.6V in a lead-free, RoHS-compliant 8.0 x 3.0 x 1.8mm package.
