Block Diagram

APDS-9960 device has Proximity sensing engine, Ambient light sensing engine, RGB color sensing engine, and gesture detection module. APDS-9960 is easy to interface with any microcontroller because it uses the I2C communication protocol.

This device has an LED which acts as a source for IR signal. When there is an obstacle or any gesture performed in front of the device, the IR signal generated by the LED or reflected back from the surface of the obstacle. This reflected light is sensed by the photodiodes present on APDS-9960. Based on the properties on this reflected light, factors such as ambient light intensity, the proximity of the object and gesture can be determined.

While using proximity sensing system the internal LED can be pulsed with rapidly switching currents which are greater than 100mA, causing an error. To avoid this certain precautions has to be considered while connecting APDS-9960.

While using APDS-9960 in a circuit, by connecting the quite analog supply to VDD and the noisy supply to the LED, power supply noise coupled back into the device during the LED pulses can be reduced.

To supply the current surge, a 1-?F low ESR- decoupling capacitor is placed as close as possible to the VDD pin. At the output of the LED voltage regulator, a bulk storage capacitor and another decoupling capacitor at LEDA pin are placed.

A 22? resistor is used in series with a VDD supply line while operating APDS-9960 from a single supply. To filter the power supply noise, a 1- ?F low ESR capacitor is used.

Where to use APDS9960?

APDS9960 is a multifunctional sensor that supports color detection, proximity measurement, and gesture detection through a single module. It can detect up to six gestures which include left, right, up, down, far and near. The range of detection is about 4 to 8 inches.

It has a very high sensitivity which makes it well-suited for operations behind dark glass. You can interface this sensor with Arduino, microcontrollers, etc to perform a variety of functions. You can use this sensor in remote controls for controlling robots and other devices.

APDS9960 Interfacing with Arduino

The hardware is simple and easy to use. The APDS9960 breakout board of the sensor operates on 3.3V due to the presence of an onboard voltage regulator.

APDS9960 consists of four photodiodes that are sensitive to different directions. Whenever an object within a detection range performs any gesture, the object reflects back the IR signal transmitted by the LED. The photodiodes detect that signal and that is how it obtains the information regarding velocity and distance of an object.

Using this information, the sensor detects the type of gesture. The sensor has different channels which detect light red, blue, green, and clear colors through IR and UV blocking filters and a data converter. The configurable interrupt controls the detect function and triggers the sensor to release the Infrared light or detect it.
