The motion sensor recognises when people move and turns on your connected light sources. The customer can choose if the lights should always turn on when the sensor is triggered by movement or only when it is dark. The customer can also choose if the lights should turn off after 1, 5 or 10 minutes. The motion sensor is powered by 2 CR2032 Lithium batteries and comes with a wall fitting that can be mounted with adhesive tape or screws. The motion sensor has a lifetime of at least 2 years before you have to change the batteries.
