    is there any idea about this? i also think about capacitor proximity sensors but these sensors detects everythings which are in front. but i want to detect only humans and animals.

    Hello,

    I do not know if the PIR sensor will work, as there is a glassplate on top of the table.
    It could be they used some light sensors as the reaction with the lamp above the table is heavy.
    There are a lot of light sensor types (area, angle, color).
    Here is a page from the EDUCYPEDIA on light sensors:
