(57) The invention relates to security alarm devices and can be used as alarm device for
registration of touches or approaching to the protected object. The invention also
provides signal transmission to the computerized user device (smartphone, tablet computer
etc.) For achieving above said goals, proposed security alarm device with the function
of alarm signal transmission to the computerized user device, comprising the independent
current source, control, signaling, indicating unit, whose input port is connected
with process controller, safety sensor. According to the invention, process controller
has the form of Bluetooth LE microcontroller. At least one capacitance proximity sensor
with active shielding and make-break electrodes is used as the safety sensor, which
is connected with platen selector and Bluetooth LE microcontroller. Capacitance proximity
sensor is combined with control, signaling, indicating unit on the one printed circuit,
Bluetooth LE microcontroller and active shield, which has the form of printed circuit
track.
