Description
The motiondetectormoduleshouldfullmajorityoftherequirements
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 infrared motion alarm unit, which
only registers objects at a temperature difference with respect to the
background, the radar motion alarm unit responds to all movements
in the direction of the sensor. With this, the movement sensitivity is
extremely high, even smallest movements nearly up to the stand still
state are recognized, because of which the modules are also very
well suitable for presence alarm units. The sensitivity can be adjusted
for a wide range over a potentiometer. With this, the module can be
tuned as per the respective application. Radar motion alarm unit works
through many materials, e.g. plastics, hence vandalism safe, hidden
installation is possible. As the operating voltage is 8 ... 15 V, which is
stabilised on the module, the unit is also suitable for battery operation
in automotive applications or for living stock vans. The open collector
transistor output connects against ground on recognizing movement.
Because of the integrated free wheeling diode against VCC, the
module can directly trigger relays and is also compatible to CMOS or
TTL logic levels. The electronics module without housing is intended
for assembly into customized devices. As such, for moderate delivery
quantities, customized adaptations or special variants are possible.
