An input/output automatic distinction counter device is provided to minimize power consumption by controlling an illumination system, an A/V, and a ventilation system automatically. An input/output automatic distinction counter device includes an input recovery sensor(10-a), an output recovery sensor(10-b), an input detection sensor IN1(101), an output detection sensor IN2(102), an input/output decision circuit(300), a counter circuit(301), and a display unit in order to perform a counting operation by distinguishing an input and an output from each other automatically. The input recovery sensor is formed to detect the input. The output recovery sensor is formed to detect the output. |
