Bellman Mobile Phone Sensor connects the mobile phone or tablet to the Bellman Alarm Clock. It tells you when you receive a call or message, even if you are several rooms away. When the display lights up, the Mobile Phone Sensor notifies the client with sound, flashes or vibrations. When the phone rings or receives a message, the sensor is activated. The alarm clock (and pillow shaker, if you have one) will wake the person sleeping using sound, flashes and vibrations.
