APDS9930 Class Reference

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

Detailed Description

• ID: apds9930
• Name: Digital Ambient Light and Proximity Sensor
• Category: light proximity
• Manufacturer: avago
• Connection: iio i2c
• Link: https://www.broadcom.com/products/optical-sensors/integrated-ambient-light-proximity-sensors/apds-9930

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(4);

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

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

    // Tested this value works. Please change it on your platform
    upm_delay_us(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;
        upm_delay(1);
    }
    light_proximity.enableProximity(false);
    light_proximity.enableIlluminance(false);
