Description
The radar module has been developed for the majority of demands
that are for door opening systems, alarm and safety equipment,
control of machines, sanitary rooms and going up to games and sports
devices. The module is suitable for a variety of applications, in which
movement or presence must be registered and based on this, the
switching process must be triggered.In comparison to passive infra-red
movement alarm units, which registers only objects with a tempe-
rature difference to the background, the Radar module reacts to all
movements in the direction of sensor. Because of this, the movement
sensitivity is extremely high, even smallest movements of almost
up to standstill condition is detected, therefore the modules are also
very well suitable for presence alarm units.Radar modules can sense
through many materials, like for example plastics, hence vandalism
safe, hidden mounting is possible.The stereo module has two I/Q
outputs at around 90° phase shift, and hence, this enables detection
of the movement direction. The module supplies an un-amplied
mixed signal as output, which must be processed in two subsequent
amplier circuit, before it can be evaluated by means of a comparator
or a micro-controller. The electronics module is meant for assembly
into customised projects as a HF-sub module.
Further application write-up and circuit examples are available on
request.
