APDS9930 Class Reference

APDS9930 Digital Proximity and Ambient Light Sensor. More...

Detailed Description

• ID: apds9930
• Name: APDS9930 Digital Proximity and Ambient Light Sensor
• Category: light proximity
• Manufacturer: Avago Technologies
• Connection: iio i2c

This sensor provides digital ambient light sensing (ALS), IR LED and a complete proximity detection system.

    // Instantiate a Digital Proximity and Ambient Light sensor on iio device 4
    upm::APDS9930* light_proximity = new upm::APDS9930(4);

    // Kernel driver implement sleep 5000-5100us after enable illuminance sensor
    light_proximity->enableIlluminance(true);

    // Kernel driver implement sleep 5000-5100us after enable proximity sensor
    light_proximity->enableProximity(true);

    // Tested this value works. Please change it on your platform
    usleep(120000);

    while (shouldRun) {
        float lux = light_proximity->getAmbient();
        cout << "Luminance value is " << lux << endl;
        float proximity = light_proximity->getProximity();
        cout << "Proximity value is " << proximity << endl;
        sleep(1);
    }
    light_proximity->enableProximity(false);
    light_proximity->enableIlluminance(false);
