VCNL4040 integrates a proximity sensor (PS), ambient light sensor (ALS), and a high power IRED into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. The 16-bit high resolution ALS offers excellent sensing capabilities with sufficient selections to fulfill most applications whether dark or high transparency lens design. High and low interrupt thresholds can be programmed for both ALS and PS, allowing the component to use a minimal amount of the microcontrollers resources. The proximity sensor features an intelligent cancellation scheme, so that cross talk phenomenon is eliminated effectively. To accelerate the PS response time, smart persistence prevents the misjudgment of proximity sensing but also keeps a fast response time. In active force mode, a single measurement can be requested, allowing another good approach for more design flexibility to fulfill different kinds of applications with more power saving. The patented Filtron TM technology achieves ambient light spectral sensitivity closest to real human eye response and offers the best background light cancellation capability (including sunlight) without utilizing the microcontrollers’ resources. VCNL4040 provides an excellent temperature compensation capability for keeping output stable under various temperature configurations. ALS and PS functions are easily set via the simple command format of I 2 C (SMBus compatible) interface protocol. Operating voltage ranges from 2.5 V to 3.6 V. VCNL4040 is packaged in a lead (Pb)-free 8-pin molding package, which offers the best market-proven reliability quality.

C++ Software Code for VCNL4010, VCNL4020, and VCNL3020

Designing the VCNL4040 Into an Application，The VCNL4040 is a fully integrated proximity and ambient light sensor. It combines an infrared emitter and photodiode for proximity measurement, ambient light sensor, and signal processing IC in a single package with a 16-bit ADC. The device provides ambient light sensing to support conventional backlight and display brightness auto-adjustment, and proximity sensing to minimize accidental touch input that can lead to call drops and camera launch.

The SensorXplorer TM is a demonstration kit designed to help evaluate Vishay’s digital sensors featured on Vishay’s sensor boards. These boards, along with their respective software modules, can be used to demonstrate and test each sensor’s functionalities, allowing the user to quickly understand how various settings affect the sensor’s results. The SensorXplorer board includes a USB to I 2 C interface chip, a 3.3 V regulator, several indication LEDs, as well as multiple GPIOs to control the functionality of each board and allow data to be read and displayed on a PC. To get an overview of available sensor boards, as well as to download the software modules and board design files, please visit: www.vishay.com/optoelectronics/SensorXplorer. Here you will also find a link next to each board showing its availability at each of our distributors. The following document covers what you get in the box and how to use the kit to explore our sensor products.

The ITR20001/T consist of an infrared emitting diode and an NPN silicon phototransistor, encased side-by-side on converging optical axis in a black thermoplastic housing. The phototransistor receives radiation from the IR only . This is the normal situation. But when an reflecting object close to ITR, phototransistor receives the reflecting radiation .For additional component information, please refer to IR and PT.
