The Aso-As-10 AC 220V Photocell Automatic Light Sensor - Street Lamp Photocell is designed to automatically control outdoor lighting by detecting ambient light levels.
It is ideal for street lamps, garden lamps, and security lighting, turning lights on at dusk and off at dawn. It is installed with the blue side facing up. The light source should be mounted on top. If it sees the light directly, it turns it off again.
