This information is passed on wirelessly to the receiver unit which has a hooter attached to it. This buzzer is pulled high by the system to hoot and thus signifying a visitor at the door.The RF communication happens in a range of 9 metres in line of sight. When the button is pressed at the transmitter side it alters the signal that is continuously sent by the transmitter side to the receiver side. When this altered change in the signal is received at the receiver, its voltage level at the respective pin goes high this triggering the hooter or the buzzer attached to that pin.
