Description
The Radar module has been developed to cater for majority of the
requirements which are meant for door openers, alarm and safety
systems, control of machines, sanitary rooms and up to games and
sport devices. The module is suitable for a wide variety of applications,
in which movement or presence has to be registered and based on
this, the switching process is to be affected. Unlike the passive infra-
red motion alarm unit, which only registers object at a temperature
difference with respect to the background, the radar module responds
to all movements in the direction of the sensor. With this, the move-
ment sensitivity is extremely high, even smallest movements nearly
up to the stand still state is recognized, because of which the modules
are also very well suitable for presence alarm units. Radar module
works through many materials, e.g. plastics, hence vandalism safe,
hidden installation is possible. The module supplies an unamplied
mixer signal, which must treated in a subsequent amplier, before it
can be evaluated by means of a comparator or a micro-controller. The
electronics module as HF-sub assembly is meant for assembling into
customised projects.
