Is there a timer?

Star Shower includes a light sensor to save electricity so it will only turn on in the dark. For more info about the projector timer check out our review page

This sensor is a photo sensitive spot so it stays on from dusk to dawn. But if you wanted to put it on a timer (remembering that the lights won’t show up during daytime) you could do so and cover the photocell spot with a black piece of tape, for example if you want to use it indoors.
