[CNX-Software] - Light sensors add “lift and learn” feature to digital signage player

Light sensors are used to turn on/off lights, adjust the brightness of displays, and more. But I’ve come across a use case I never thought of: object presence detection. In the digital signage work, such features if called “lift and learn”, and light sensors are used to detect when an object is present and play a video or display information about the product. That concept came to my attention when I saw a photo of Mekotronics R29 digital signage player with several cables coming out of the device and attached to what looked like white hockey pucks and turned out to be light sensors. Apart from the light sensors, Mekotronics R29 specifications are pretty standard: SoC – Rockchip RK3399 hexa-core processor with 2x Cortex-A72 cores, 4x Cortex-A53 cores, Arm Mali-T860MP4 GPU, 4K VP9, H.264, H.265, and 1080p60 VC-1, MPEG-1/2/4, VP6/8 video decoder System Memory – 4GB DDR Storage – 64GB [...]
