Depending on the model, some of our projectors (Star Shower) include a remote, while others have a light sensor that turns it on at dusk and turns it off in the morning. The only downside of the sensor models is that if you live near a street light it will turn off automatically due to the excess light, since it will think it is already dawn. You can easily surpass this problem if you blind the sensor with a dark tape, such as isolating tape.
