The Yale Smart Home SR-PETPIR motion detector is suitable for an expansion for Yale smart Home alarm systems. Easily place the sensor in any desired place in the home with the adhesive strip. The motion detector registers if there's someone in the house. With an alarm, you receive a notification on your smartphone which allows you to jump into action immediately. Do you have pets? Not a problem, since the motion detector ignores the presence of pets up to 25kg.
