![]() Connecting APDS9960 Gesture sensor to Arduino. The measurement data is provided as 16-bit results. The color and ambient light sensing functionality uses an array of red / green / blue / clear filtered photodiodes with IR filters over them to minimize the impact of IR light. When an object is detected, the reading will approach 0 as the object moves closer and will read 0 at about 1″ distance from the sensor. With no object detected, the sensor will report 255 or something close to that reading. It has a maximum detection range of about 6″ depending on the surface and a minimum range of about 1″ Both the IR transmitter LED and photodiode detectors are located in the small black package. The proximity sensor uses reflected IR to determine the relative distance to an object. Gesture detection works best when the object passes within a distance of 1 to 2 inches from the sensor. The reflected IR by the photodiodes is converted to signals that are translated into basic up, down, left and right movements or gestures. The direction of movement of the object is determined by which photodiode the object first passes. These photodiodes are placed in such a way that an object moving from one direction to the opposite side will first approach one photodiode and then the other. This sensor has four photodiodes and an IR LED arranged as illustrated below.ĪPDS9960 Gesture detection is made possible using the four photodiodes that reflect IR radiation from the built-in IR LED. The APDS9960 sensor is used for detection of gestures, sensing proximity and detection of color and ambient light intensity. The jumper is also closed by default but in case you want to use external pull-up resistors then you can open it. I2C PU – This is a 3-way solder jumper used to connect the I2C 10K pull-up resistors to the SDA and SCL line on the board circuits.However, if the jumper is open, you have to provide separate power supplies for VCC (2.4 – 3.6V) and VL (3.0 – 4.5V). PS – This solder jumper comes closed by default and is used to connect the power supplies of the sensor and IR LED together therefore you only need to supply power to the VCC pin.The breakout board also has two solder jumper pads. Output is open-collector so requires pull-up resistor and is connected to an interrupt input of a microcontroller when used. VCC – Power supply connected to 3.3V of the microcontroller.GND – Connection to ground of a microcontroller.It is used when the PS jumper is removed and should have a voltage of 3.0 – 4.5V DC. VL – This an optional power supply for the IR LED.There are six header pin connections namely ![]()
