What kind of switch socket is generally used in the corridor

What switch socket is generally used in the corridor, what kind of switch socket is the most energy-saving and environmentally friendly?

In fact, this problem has been solved in the product development of early remote control socket manufacturers. For example, our previous common voice control lamps, voice control lamps are actually using the sound as the "switch command" of the lamp, when there is sound control lamp The switch socket is connected to work. However, this may be because the noise will also light up the light.

Nowadays, most of us use the human body sensor switch socket, which can sense the movement of the human body. It is a passive human body detector. It can automatically control the light fixture by detecting the brightness of the surrounding environment and the movement of the human body (temperature change).

Quiet does not disturb others. Rest, the person in the detection range moves, the switch is opened, after the person leaves the detection range, the switch delays after several tens of seconds, which greatly facilitates the control and management of various public places, and achieves the purpose of energy saving.
